  • stop valves (globe valves); 
  • check valves; 
  • butterfly gates; 
  • ball and plug valves. 

Tested unit connection type

  • flanged (according ASME B 16.5, GOST 12815, etc.); 
  • welded ends (according ASME B 16.25, GOST 16037, etc.).

  • 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. 
  • 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. 
  • 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. 
  • Fast clamping and centering of the tested valve is ensured due to synchronized travel of the clamps. Allows quick and precise testing of large number of serial manufactured valves.
