I have a customer that has put two back pressure regulators in parallel in a fluid application. They are using one as a primary and one as a back up in case the first one fails.

i am in the need and the urge to purchase a four way valve 10" 300# RF (it is for a bidirectional prover) but cannot find any non-US manufacturer or supplier.

Does any know if there is any guide for valve packing selection based on service and temperature?

My Client gave me a datasheet of a ball valve, in which an electroless nickel plating surface treatment (min. thk. 50 microns)is required for a standard (non corrosive) service.

Have a small ball valve (1" inch bore, 1.875" ball) and need to have a torque spec for sealing/seating the ball and seals with a retaining nut threaded in.

A supplier brought to my attention that I had an unusually high velocity going through a check valve in a PS design I was working on...

I'm looking at an oil export system that has two valves in parallel. Only one at a time should be controlling the flowrate in a cascade level onto flow control.
