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
