Different types of Needle Valves?

The systems while construction or any industrial entities that deal with the inflow or outflow of liquids, gases, and steams, needs a strong and resistible operating system.

This is done by using a Needle Valve. For more detail, let's have a look at the different types of needle valves. 

Types of Needle Valves 

There are 2 different types of needle valves. Here they are: 

1. Motorized Needle Valve

These needle valves don’t have a hold for a physical system, but rather, obtain an electric or pneumatic actuator to relate to and whirl the plunger. These can be remotely regulated, utilized in a closed-loop structure, and put on a timer to properly supervise the tide rate remotely.

2. Angle Needle Valve

These needle valves whirl the outcome from the basin by 90 degrees rather than in-line. A similar system theory pertains, but the 90-degree curve can enable adequate system integration. 

How to select a needle valve? 

When you require a needle valve, you need to remember some of the features. They are: 

1. Material

When you decide to purchase needle valves you should be firstly acknowledged by the materials of which needle valves are being produced. Usually, the alloys are preferred for producing needle valves. The most common materials are copper and steel. 

a. Brass

The Brass is commonly used for the production of needle valves as are desirable for high-temperature applications hydraulic systems, gas piping, and drinking water. They are applicable for impartial and non-corrosive outlets, with the most ordinary execution existence for drinking water appeals.

b. Stainless steel

Stainless steel is usually known for its chemical obstruction. This makes it suitable for having a stainless steel needle valve. Stainless steel is a durable material for needle valves that can resist high pressures and temperature. 


2. Pressure

The standard unit for measuring pressure is psi. The pressure of a needle valve is being decided and produced by its uses such as when the high-performance needle valves are needed, it is generally of 10000 psi (689 bar) pressure at 100°F (38°C). This same is applicable in low pressures but it is specially designed on order. 

a. Port & orifice size

The ports usually consist of connection ends with differences such as male and female ends. The needle valves are in a large range of port and orifice sizes. You need to ensure the correct port size and orifice size that will secure profitable flow and system process with limited risks of damage and leakage.

b. Temperature

The most important thing to remember while selecting a needle valve is to be clear with the temperature at which you are going to use or operate the needle valve. This will help in the smooth flow and working of the needle valve for the desired period.
