  • Adjustable valve testing position: valves intended to operate vertically are tested vertically, valves intended to use horizontally are tested horizontally;
  • Quicker valve mounting and centering because of three simultaneously moved claws
  • No airtraps during filling, the valve is filled vertically and then tilted to horizontal position
  • Possibility to observe sealing surface during leakage test (45 degrees tilted valve)
  • Clamping of tested valve is provided by hydraulic cylinder. Optionally test bench can be equipped with proportional clamping control system, which excludes axial compression applied to the valve body during clamping by hydraulic cylinder, during high pressure testing.
  • Two-sided gate sealing during tests does not require the tested valve rearrangement, which significantly reduces the test time.
  • The bench is equipped with the water-collection tray.
  • 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.
  • Increased-diameter hoses reduce the time of the valve filling with the test medium.
