  • Clamping of tested valve provided by hydraulic cylinder, optionally test bench can be equipped with proportional clamping control system, which excluding axial compression applied to the valve body during clamping by hydraulic cylinder, during high pressure testing.* 
  • The two-sided gate sealing during tests do not require the tested valve rearrangement, which significantly reduces the test time. 
  • The bench is equipped with the water-collection tray with stainless steel tank.* 
  • The test preparation time is significantly reduced by using the high-pressure fast coupling hoses. 
  • The bench is quickly adjusted to face-to-face dimensions of valve by using the electrically driven cross-head. 
  • The patented design of the self-sealing adapters exclude axial compression during the tests, which ensures the test reliability, protects the valves against deformation, and extends the valve life.* 
  • All water-wetted parts are corrosion-proof. 
  • The bench can be equipped with replaceable sealing adapters.* 
  • Increased-diameter hoses reduce the time of the valve filling with the test medium. 
  • Turning upper cross-head is used to simplify the valve installation procedure before testing. 
  • The test preparation time is significantly reduced by using the high-pressure quick-connect hoses. 
  • Fast clamping and centering of the tested valve is ensured due to synchronized travel of the clamps. 
  • Test bench allows visual detection of seat leakage point.
