    Test units stationary and horizontal

Test unit for testing shut-off valves and control valves:
  • Test unit with horizontal hydraulic clamping system and 90 degree rotation for clamping the valve at both flanges between the test tables.
  • The Clamping system is able to test valves in a horizontal, vertical or inclined position.
  • Advantages of the rotating clamping system are: it is easier to load the valve with actuators inside the clamping system in the horizontal position. In a vertical position the evacuation of the air out of the valve is assured during filling with water.
  • For testing valves with butt-weld or socket-weld connections, special seal adapters are required
  • Test units are also available in combined version with two clamping devices of different design, working range or clamping force

Hydraulic clamping systems are available with clamping force of:

  • 30, 55 and 85 tons

Standard features:

  • Hydraulic clamping system
  • Hydrostatic test circuit
  • Air test circuit
  • Nitrogen test circuit
  • Bubble counter for leak test
