Functions of a 3 Way Manifold Valve

Have you heard about the amazing 3 way manifold valve? You must hear but you won't be able to understand it properly. 


To make you clear here is the best manufacturer and supplier of valves Techtube. Let's know about this and order it now for smooth functioning. 

Some information about 3 way manifold valve

A three-way manifold valve is a mechanism that prevents the capsule from being over-ranged. It also permits the transmitter to be separated from the process loop. It comprises two block valves, one for high pressure and the other for low pressure, as well as an equalizing valve.


Manifold valves are available in a variety of sizes, forms, and dimensions and are used to measure the pressure communicated. A three-way manifold valve, for example, is utilized to ensure that the block is not over-ranged. It includes two drain valves and two block valves. 

Functions of a 3 way manifold valve

  • These valves are frequently recommended by 3 way manifold valve manufacturers in India because they allow the transmitter to be isolated from the process loop.
  • A high-pressure block valve is one of the block valves in the 3 Way Manifold For Pressure Transmitter, whereas a low-pressure block valve is the other. To equalize the pressure on both sides, the drain or equalizing valve is inserted between these block valves.
  • The most important benefit of employing a remote-mounted 3 Way Valve Manifold Swagelok is that it protects the instrument from temperatures that are too high or too low by increasing or decreasing the process temperature. 3 Way H Type Manifold Valve is utilized in a variety of sectors, including petrochemical, chemical, and oil.

Incorporation of Three-Way Manifold Valving Transmitter into Operational Groupings

  1. Make sure all of the valves are shut.
  2. Open the equalization valve so that the pressures on both sides of the transducer are equal and the differential pressure is zero.
  3. Check for spillage from both the high and low-pressure sides of the transmitter as the High-Pressure block valve is gradually opened.
  4. Close the equalizing valve, and the pressure on both sides of the transmitter will be locked.
  5. Set the operating differential pressure by opening the low-pressure block valve and applying process pressure to the low-pressure side of the transmitter.
  6. Currently, the transmitter is in use.

Taking the Transmitter Out of the Benefit

These are some of the benefits such as : 

  • The low-pressure block valve should be closed.
  • Turn on the equalizer valve.
  • The high-pressure block valve should be closed
