TEST BENCHES FOR SHUT OFF VALVES DN 400…1400 MM

PURPOSE:• testing of the body part materials for strength and density (shell test);• gate tightness tests (leakage test);• environmental leakage tests (including gland seals), backseat test;• operation test (functional test).TESTED ITEMS:• gate valves;• ball valves;• butterfly valves;• check valves;• plug valves.TESTED UNIT CONNECTION TYPE:• flanged (according ASME B 16.5, ASME B 16.47,GOST 12815 etc.);• welded ends (according ASME B 16.25, GOST, etc.);*• set of sealing adapters available.*ADVANTAGES:- Clamping of tested valve provided by hydraulic cylinder,optionally test bench can be equipped with proportionalclamping control system, which excluding axialcompression applied to the valve body during clampingby hydraulic cylinder, during high pressure testing.*- Clamping unit can be provided with radial sealing type orself-sealing adapters.*- The two-sided gate sealing during tests do not require thetested valve rearrangement, which significantly reducesthe test time.- The bench is equipped with a special system for airremoval from the tested valve, which improves safety,productivity, reliability of the obtained data, and obviatesthe need for additional air drain.*-The bench is equipped with the water-collection tray withstainless steel tank.*– The test preparation time is significantly reduced by usingthe high-pressure quick-connect hoses.-The bench is quickly adjusted to face-to-face dimensionsof valve by using the hydraulically or electrically drivencross-head.- The patented design of the self-sealing adaptersexclude axial compression during the tests, whichensures the test reliability, protects the valves againstdeformation, and extends the valve life.*- All water-wetted parts are corrosion-proof.- The bench can be equipped with replaceable sealingadapters.*- Increased-diameter hoses reduce the time of the valvefilling with the test medium.- Test-bench can be equipped with valve lifting platformsfor valve positioning and support during testing.*
