Hi all. Just wondering, is it possible to safely remove or plug bleeder (PRV) in an ESD valve? Not thinking of any special manufacturer here, only in general.

I am trying to determine the resistance coefficient, K, of a single-offset, butterfly style damper. Since, there is no readily available data for dampers I was going to utilize the K values of butterf

A valve that doesn't change the volume of the system on activation (i.e. which prevents hydraulic shock), can be operated remotely and has short activation time.

If you are responsible for leaks in peoples homes, helium may be usefull for those tough to find leaks, but I doubt the return on the investment for these small leaks will be worth it to a water purve

A valve to API 6A and NACE MR0175-2003. This valve has an internal part that is a nonpressure-containing (but pressure-controlling) component.

The oxygen flow rate is set by adjusting the air pressure (using a pressure regulator)on a pneumatically controlled diaphragm valve which moves a sliding gate in the oxygen supply line.

Butterfly plate shaft is at an angle to improve the sealing. It will be great help if any one could explain how it is achieved?

I am working in a valve factory. I have a question about the dimension for ball valve bore. The description of the valve is given as follow.
