Needle Valves- How Are They Different From Flow Control

Needle valves are manufactures in India that have a narrow and tapering point at the end of the valve stem. This is the stem of the valve, which is lowered to block or restrict the flow.

The needle valve stem's delicate threading design, along with its huge seat area, ensures accurate resistance. These valves are used to control and check the flow of liquids and gases into the system's delicate gauges, which are vulnerable to harm if exposed to high pressure.

These valves are also seen in industrial machinery when the flow must be brought to a complete stop. They're also used in situations when a precise flow modification is required, or where a modest, regulated flow is required. These valves are versatile enough to be used as both on and off valves, as well as in a throttling system.

Difference between Needle Valves and Flow Control

Flow Controls and Needle Valves are used to slow actuator speed by reducing the rate of flow in a pneumatic circuit leg. Although both have the same basic function of flow restriction, the Needle Valve regulates flow in both directions (bi-directional) whereas the Flow Control Valve only regulates flow in one way (enabling free flow in the different direction).

A precisely threaded stem allows gradual adjustment of the amount of controlled flow passing through the valve in both the Flow Control and the Needle Valve. Flow enters the input port, passes through a tapered stem-sized aperture, and exits the output port. The Flow Control has a F2F by-pass check, which allows for rapid unrestricted flow from the valve.

There are two sorts of Flow Controls to consider, and their selection and location within a pneumatic circuit have a significant impact on an actuator's performance.

The flow to an actuator is restricted by a Meter-In Flow Control (also known as a Reverse Flow Control).

A Meter-Out valve, which regulates the exhaust flow from an actuator, is the most often utilized Flow Control.

It's critical to understand your flow rate requirements before choosing a Needle Valve or Flow Control for your pneumatic system. The related actuator's speed is determined by how rapidly it can be filled with air at the intake and expelled at the output.

Conclusion

Needle valves are used to ensure that the fluid travels through the valve and spins 90 degrees before passing through the seat orifice. A rod with a cone-shaped tip is included with this seat. The valves are used to control the flow of liquids and gases at low flow rates.

Stainless Steel Female Connector Tube Fittings

Everything is set up and maintained using the connection. Every part of human emotions, such as emotional ties, is intertwined with scientific aspects, such as electrical connections. It is vital to have a working relationship with the organizations that aid you or play a key role in your endeavors when it comes to any form of business or construction project.

Female connectors are one of the connecting pieces of any part's joint. Let's review some facts concerning female connector’s tube fittings to make sure you understand.

What are Female connector’s tube fittings?

Female Connector Tube Fittings are a type of industrial fitting that connects various types of tubes and fractional ports to a male parallel pipe thread. These Female Connector Tube Fitting are made from Round Bars and are forged.

Female connectors are used to send electrical, physical, or digital communications. A female connector has one or more holes into which the exposed plug-type conductor of a male connector can be inserted for a secure connection. Female connections can be identified by their physical characteristics. When the male connector is removed, the conductor of a female connector is not exposed like that of a male connector, therefore it cannot come into contact with items by accident.

Female connectors can be found in a variety of places, including regular outlets, phone jacks, and Ethernet jacks. The most common female connector is a two- or three-prong electrical outlet, sometimes known as a wall outlet. Common connectors include telephone jacks, headset jacks, coaxial cable chassis connectors, and D-shell connectors for computer serial and parallel ports.

Why Certain Tube Fittings Connection Are Better Than Others

Measurement and control are at the heart of instrumentation. The field of instrumentation engineering focuses on the design and configuration of process systems. Instruments are devices that are used to measure system properties in a process system. Valves, actuators, pressure gauges, and even IIoT-enabled valves are among the instruments and components that may sense and communicate data about the matter that passes through them as well as their surrounding situations.

 

Most instrumentation connections on the market, from tube fittings to process valves, do not match the rigorous standards that many applications demand. Tubing and tube fittings, often known as compression or instrumentation fittings, transport fluid between system components. Like instrumentation valve connections, their design can range from rolled to cut threads to single to multiple ferrules. Regardless of design, the connection will always fail if it is not properly installed.

 

Single versus Double Ferrule

Single ferrule tube fittings are utilized in less critical applications than double ferrule fittings because they have a lower pressure rating. They do, however, have a popular advantage. Compression fittings with a single ferrule feature one less item, making them faster and easier to install, especially in small spaces. Despite this advantage, twin ferrule fittings have become the standard in the design of measuring and control systems.

 

Double ferrule tube fittings come in the same designs and sizes as single ferrule tube fittings. The double ferrule design consists of a front ferrule that is similar to the single ferrule but with a back ferrule ring that seats into the front ferrule when inserted, resulting in a tighter seal. Due to their strong mechanical hold on the tube, double ferrule compression fittings provide a superior connection. Furthermore, they are preferred for usage on the tubing of varying hardness levels and wall thicknesses.

 

Conclusion 

Instrumentation fittings with rolling threads are best for most applications, and double ferrule tube connections should be used for important operations for greater leak resistance and endurance under high pressure, temperature, and vibration. Threads that have been rolled have better physical properties, more precision, and a high degree of surface finish. They are uniformly produced at high rates of production with no material waste, resulting in cost savings. This should be a top priority when choosing fittings. Another factor to consider is whether to use double ferrule fittings, which have a stronger mechanical grip on the tube than single ferrule fittings.

 

Instrumentation tube fittings are utilized in a variety of industries, including oil and gas, aerospace, industrial, construction, and agricultural machinery.

What are Socket weld fittings?

The bottoming clearance in a socket weld is commonly used to alleviate residual stress at the weld's root that may occur during the weld metal's solidification, as well as to allow for differential expansion of the mating parts. Techtube is the best supplier and manufacturer of socket weld fittings. Let's go. 

 

What is a socket weld fitting? 

A socket weld is a pipe extension characteristic that pertains to injecting a pipe into a recession in a valve, fitting, or flange. Socket Weld fittings, in a contrast to buttweld fittings, are mostly used for tiny pipe diameters (Small Bore Piping), often piping with a nominal diameter of NPS 2 or less.

Fillet-type seal welds are obtained to link pipe to valves and other fittings, as well as to other regions of pipe. Where the benefits of excellent leakage integrity and structural strength are important design considerations, socket welded joints are a desirable solution.

Due to the use of fillet welds and abrupt fitting geometry, fatigue resistance is lower than that of butt-welded construction, but it is still better than that of typical mechanical joining.

 

Advantages and Disadvantages of Socket Weld fittings

Advantages

  1. For weld preparation, the pipe does not need to be beveled.
  2. Because the fitting assures good alignment, in theory, no temporary tack welding is required for alignment.
  3. The weld metal is unable to penetrate the pipe bore.
  4. They can be used instead of threaded fittings, reducing the danger of leaking.
  5. Because radiography is not possible on the fillet weld, proper fitting and welding are essential. Surface examination, magnetic particle (MP), and liquid penetrant (PT) inspection procedures can all be used to inspect the fillet weld.
  6. Because there are no stringent fit-up requirements and no special machining for butt weld end preparation, construction costs are lower than with butt-welded connections.

 

Disadvantages

  1. The welder should ensure an expansion gap of 1/16 inch (1.6 mm) between the pipe and the shoulder of the socket.
  2. The expansion gap and internal spaces vacated in socket welded networks facilitate deterioration and make them minorly suitable for corrosive or radioactive plasters where solids hype at the seams may result in operating or sustenance problems. Normally assign butt welds in all pipe sizes with exact weld penetration to the inner of the piping.
  3. Socket welding is incompatible with Ultrahigh Hydrostatic Pressure (UHP) in Food Industry applications since they do not allow full penetration and remove overspread and openings that are very hard to tidy up, developing basic leaks.

How to choose a 2 Way Manifold Valve?

Have a 2 way manifold valve from Techtube but before that receive some insight and data viewing it. Let's go. 

 

What is a 2 way manifold valve? 

A two way manifold valve keeps the capsule's span from being outdone. It is also feasible to separate the transmitter from the technique circle. This system consists of two block valves, a high-pressure piece valve, and a low-pressure piece valve.

 

Shutting down the block valve and unlocking the drain valve is the method for measuring pressure on a pressure transmitter. You'll need to connect the drain valve to a pressure generator to test the pressure after you've cleared it. A two way manifold valve is also known as a block and bleed valve.

 

Things to be remembered while choosing a 2 way manifold valve

Everything needs to be checked before placing the order. Likewise, you can have the below-stated points while having your 2 way manifold valve. Let's begin. 

1. Material

Metal or plastic can be used to make a two-way manifold valve. However, because the resistivity of various materials varies, it's vital to know everything there is to know about the material in your two-way manifold. This will aid in the escape of any damage while fluids or gases are being distributed.

 

2. Port size

For the management valves and fittings required for an application, manifold valves provide a combination of intake and outcome refuge options. To speed up induction in the collector's production refuges, pick parts with similar thread diameters while creating your fluid control path.

3. Number of Stations

2 way Manifold valves are being recommended from two to ten stations for the collectors. But, you can operate the stations up to a certain limit only when assigned. 

4. Spacing

2 way Manifold valves should contain an accurate spacing between their reaction ports. This will help maintain your fluid and gas release operation operating smoothly. There should be no clashing or summit of your aspects with other units. 

5. Operating Pressure

The operating pressure of a two-way manifold valve is determined by the material used in it. The working pressure of your 2 way manifold valve should be determined by the manufacturer who is creating your 2 way manifold valve for you.  

6. Placement

When building a two-way manifold, you need to think about both the economical and physical aspects. As a collector or producer, you must work smartly and efficiently with limited resources rather than wastefully extending your resources

Manifold Valve- Uses, Types, Industries

To get the best manifold valve from the best manufacturer and supplier Techtube, let's take a look at its type and use. Let's get started. 

Uses of Manifold Valves

Depending on the need, manifolds are employed in my various fluid power applications. Manifolds can be used to mount valves or to consolidate pipework in both hydraulics and pneumatics. They are the contact between the valves and the ports to be piped into when they are used for installing valves.

 

Manifolds can also be used for purposes other than valving. To save on plumbing, a manifold might simply be a chamber with two or more ports connected in series. A return line manifold with six smaller ports connecting to one large tank port, for example, eliminates the need for a series of expensive together fittings, saving money and minimizing the risk of leakage.

 

A manifold can also be utilized in pressure lines, which cleans up the plumbing and improves the aesthetics. Now let's get to the types of manifold valves. 

Types of manifold valves

Manifold valves come in four different forms. They are as follows:

 

1. Inline or direct connect Valve for the manifold

Direct connect manifolds have female or male process connections and are also known as inline, block and bleed, and block and bleed manifolds. To connect this type of manifold to transmitters, male National Pipe Thread is used (NPT).

 

For these manifolds, only a 2-valve assembly with a 12" NPT process connection is available. Female process connections are normal on these manifolds, although male process connections are also available.

 

2. Coplanar Manifold valve

Valve Manifolds that are coplanar 3-valve assembly with direct process connection on a coplanar manifold Valve Manifolds that are coplanar 3-valve assembly with direct process connection on a coplanar manifold Valve Manifolds that are coplanar 3-valve assembly with direct process connection on a coplanar manifold Valve Manifolds that are coplanar 3-valve assembly with direct process connection on a coplanar

The process connection enters from the bottom of coplanar manifolds, obviating the requirement for a separate process connection.

 

3. Traditional Manifold valve

Traditional manifolds have a side connector. It's possible to get them with two or three valves. Some traditional manifolds require a flange, whereas others do not. These manifolds come with 12" and 14" process connectors.

 

4. Conventional manifold valve

Conventional Manifolds are a type of manifold that has been around for a long time. A traditional manifold has a 3-valve arrangement. If you need a totalizer manifold on the side of a process flange rather than immediately on a pressure transmitter sensor, you'll need to use a typical manifold. Alternative and classic flanges are terms used to describe these flanges. Manifolds with two, three, or five valves are offered. On the instrument side, there is a 2 18" center-to-center connection.

How does a Ferrule Connector work?

In household and industrial wiring, twisted wires must be inserted into screw terminals or spring-loaded connectors. For industrial equipment, it may take hundreds or even thousands of these connections to automate a task. If even one of these wires comes loose or breaks, you're most likely expecting costly downtime. 

 

Each connection is therefore fundamental. While the flexibility of the braided wire allows for much easier routing than one would expect from a solid core wire, the ends tend to stick out. This makes the actual connection to a screw or spring-loaded connector a bit risky. In a perfect world, you would have thread woven in the middle and solid at the ends. 

What is a ferrule? 

The ferrule is the small equipment or tools that are very useful for joining, fastening, reinforcing, and sealing any number and type of joints. A ferrule is generally made up of metal and we proposed to the users in various shapes such as circular, narrow, etc. A ferrule can be of plastic but is less preferred due to its resistivity. They can be used in plumbing systems for sealing and ensuring complete prevention of fluid or gas leakage. A ferrule is deformable in that it can be made as per the desired and required situation. 

Working on ferrule connector

A ferrule connector is generally used with wires. With regards to wiring, a ferrule is a short deformable metal cylinder, by and large made from tin-plated copper. This short cylinder (or long ring) is put over a segment of abandoned wire reaching out from stripped protection, then compacted with a creasing instrument to keep the strands intact. Ferrules examined here additionally include an erupted segment toward one side, which effectively directs the strands into the principal pleated area and gives a push to the limit support. 
 

When folded, the group becomes what for practical purposes resembles the end of a strong central cable. Flaring the ferrule has a few advantages, including the strain relief mentioned above and the way each strand of a cable can now be embedded in a connector without fear of a pair being uprooted sideways after termination. Ferrules significantly reduce clogging of the contact between the cable and connector and even help reduce oxidation of the stranded wires because there is no air gap between them.

Order a ferrule connector from the best manufacturer and supplier Techtube. Enjoy the accuracy and perfection in your work!!

How to choose a Needle Valve? | TechTubes

 

Are you using a needle valve or are you ready to get started? We've put together a needle valve guide in case you come across an unfamiliar term while working on a project. 
 

The guide describes what they are, how they work, and some of the different ways they are commonly used. Reviewing the summary expands on the function and How to choose Needle Valves.

What is a needle valve? 

Needle valve: Definition, type, function, and application: Needle valves, sometimes referred to as spool valves, are pressure and flow control valves that help accurately control the pressure and flow of fluid flowing through the pipeline. The adjustment or operation of the Needle Valve is so delicate that it allows for very precise control of fluid flow. These valves are commonly used for low flow applications and high pressure drops from inlet to outlet. 
 

However, it can also be used to block or block the flow of liquid in the pipeline. Its actuation mechanism is similar to that of a piston check valve, except that the size of the piston used for the Needle Valve is relatively thin. This figure shows different parts of a generalized needle valve. 

The function of the Needle valve

The needle valve opens and closes the passage (orifice) between the inlet and outlet by the movement of a tapered needle perpendicular to the direction of flow. The needle is directly connected to the plunger or shaft. The handle is further connected to the handle and uses the fine internal thread of the hood to convert rotary motion into reciprocating motion. 
 

When the handle is given a rotational movement, a subtle up-and-down movement of the piston occurs, which opens and closes the opening. A locknut is also attached to the top of the attachment to prevent the plunger from completely disengaging from the female thread of the attachment. As the needle moves down, it contacts the valve seat and provides a leak-free block of fluid in the pipeline. 
 

The attachment is connected to the valve body via a screw system.

Valve activation can be controlled manually or automatically by rotating the handle. Automatic needle valves are generally operated electrically or hydraulically. The motor or hydraulic actuator precisely controls the position of the stem in the valve body (bonnet) according to external requirements. 

Applications of Needle valve 

The most common use of needle valves is to regulate the flow and protect the fragile gauge from damage from sudden pressure surges of liquids and gases. Needle valves are ideal for systems that use low flow, lightweight, and low viscosity materials. Needle valves are typically used in low-pressure hydraulic systems, chemical treatments, and other gas and liquid applications. 
 

Another feature of the needle valve is that its material also allows it to be used in high temperature and oxygen applications. Needle valves are usually made of stainless steel, bronze, or metal alloys. It is imperative to choose a needle valve made of the right material for the service you need. In this way, the longer service life of the valve is guaranteed and the system can operate smoothly and safely. 

Selection criteria of Needle valve 

 Needle valves can be selected based on four main criteria. Material, pressure, port and orifice sizes, and temperature. The most common materials used in the manufacture of needle valves are stainless steel and brass. Brass valves are suitable for non-corrosive applications such as drinking water flow systems. Stainless steel valves are commonly used for highly corrosive media such as seawater and acids, both materials can withstand the high temperatures of liquids, but stainless steel valves are durable and corrosion-resistant. Is better than brass needle valves.
 

The valve can be selected according to the pressure rating. The rugged needle valve can withstand pressures up to 415 bar. However, some needle valves can handle pressures up to 690 bar. Needle valves are available in a variety of port and orifice sizes. Typical needle valve connection sizes range from 2mm to 12mm.
 

Proper port and orifice sizes can increase flow efficiency and prevent system leaks. Needle valves are suitable for a variety of temperature applications. It can easily handle both very low and high temperatures, depending on the resistance of the sealant. Teflon sealant can withstand temperatures from 54°C to 232°C. In contrast, the sealant polyetheretherketone (PEEK)  can reach temperatures up to 315°C.

Types of  Needle valves 

There are basically two types of needle valves, which are explained below.

 1. In-line needle valve: (type of needle valve) 

These valves have inlet and outlet openings aligned. These valves can usually be mounted on straight flow systems.
 

 2. Angle needle valve: (type of needle valve) 

These valves have inlets and outlets at specific angles. A 90-degree elbow is typically installed between the entrance and exit to improve system integration. This type of valve is used where the pipe is bent.
 

We have briefly described the components of the needle valve here, but there is not enough space to describe all of the configuration variations offered by the various Needle Valves Manufacturers available. 
 

There are so many choices and variations, so be sure to work with a company that is familiar with all the options available. If you are looking for a Needle Valves Supplier, then Techtubes will be the best option for you!!

These double ferrule fittings fittings are available in both metric and fractional tube sizes. Wrapping the union nut around the tube will stain the ferrule and create a strong seal. Double ferrule compression fittings provide a leak-free connection to all tolerances in the tube outer wall, thickness, diameter, and material hardness.

About Double Ferrule Fittings

Double ferrule compression fittings are the most common equipment fittings. They are regularly used in process measurement and control systems in the aerospace, defense, chemical processing plants, medical devices, oil and gas industries. The compression fitting consists of three components: nut, body, and ferrule (single or double). This design creates a sequential grip on the tube. Instrumentation tube fittings are U.N.E.F. or (United National Extra Fine) threads, the size of which is determined by the outer diameter of the tube used. 
 

The ferrule becomes a coin and is compressed into the tube, providing a firm grip on the surface of the tube. The male side of the Double Ferrule Instrument Fitting has a hole that matches the outer diameter-OD of the tube. In addition, an inner cone is used. The seal is between the front ferrule and the cone. Hold the tube in place by tightening the nut and letting the front and rear ferrules swage into the tube to secure it firmly. This allows flared-free tubes to be used with these connectors.
