VALVE TESTING
PSV test benches and clamping units
Complete PSV test benches built in Singapore, combining a hydraulic clamping unit and test panel for set-pressure (pop) and seat leakage testing of flanged safety valves up to 12 inches. Liquid testing up to 15,000 psi (1,034 bar) and gas testing up to 10,000 psi (700 bar), for workshop or on-site use.

THE APPLICATION
Built for repeatable PSV testing
A PSV test bench holds the pressure safety valve securely and raises pressure in a controlled way until the valve lifts, so its set pressure can be verified and recorded. A hydraulic clamping unit makes it quick to mount and change valves without bolting each one to a test flange.
PS Technology supplies PSV test benches as a complete package: hydraulic clamping unit and test panel, designed and built at our workshop in Singapore for workshop or on-site recertification.

FAQ
Frequently asked questions
What size valves can the PSV clamping unit hold?
Flanged pressure safety valves up to 12 inches.
What test pressure can the PSV test bench reach?
Liquid testing up to 15,000 psi (1,034 bar) and gas testing up to 10,000 psi (700 bar), with separate low-pressure circuits up to 200 bar for lower set pressures.
Is the clamping unit supplied with a test panel?
Yes. We supply complete PSV test benches: a hydraulic clamping unit together with the test panel.
Can PSV testing be done on site?
Yes. Our PSV test benches are used both in workshops and on site.
Can the bench test seat leakage?
Yes. Our PSV test benches include a bubble counter for seat leakage (seat tightness) testing after the set-pressure test.
Can it test valves for gas and liquid service?
Yes. The bench has both gas and liquid test circuits, so it can test safety valves for gas and liquid service.
Do you supply PSV test benches overseas?
Yes. We have supplied PSV test benches to customers overseas, including in Portugal, with control panel labels in the customer's language.
