Valve test benches

Hi.
I am interested in finding Valve test benches designed for seat leakage and body testing of all kind of valves. It could be new or used.
Thanks in advance

RE: Valve test benches
As a point of interest, check the test times listed in either API 6D or ASME B16.34. Not very long.
If you are talking about testing PSV set points then most people try to test in place. For small valves install external valves. For large pilot operated valves buy a test kit for the valve.
For testing the flow capacity of PSVs I do not know anyone who performs this type of testing after it is in service.

Many Owner/Users make a practice of Testing ASME Sec. I, Boiler Valves (Drum & Superheater) in place utilzing Auxiliary Lift Devices. Such Equipment is very expensive and typically rented along with a qualified Technician to Operate it. However, the National Board of Boiler & Presure Vessel Inspectors administers a program for Pressure Relief Valve Repair (NBIC RA-2200, "VR" Stamp Program) which permits Owner User Testing of ASME Sec. VIII, Process Steam PRVs on Air. We have many clients who choose this option, including 10 Nuclear Plants, several Pharmaceutical Plants and numerous Petro Chemical Operations.
This Test Equipment can be utilzed for Pilot Operated Relief Valve Testing as well as Spring Loaded PRVs. The Liquid Test Bench is also capable of hydrostatically testing Manual Valves (Gates, Globes & Checks) as well as seat tightness testing.
I hope this information is helpful. The e-mail address is
