Universal test units for clamping, testing and stroking the trim of any globe-, camfex- or waver type control valve with double or single port, diaphragm or piston actuated in the range 1"- 24" / DN25 - 600 mm.

Test systems
Analogue, digital or semi-automatic (computerized) test systems for testing the body- & seat tightness. The test systems feature a combination of digital flow meters and a laser bubble counter for measuring the seat leakage according to the international standards.

Clamping systems
Horizontal and tilting clamping systems for clamping the valve on the inlet only or closing both ends.

Monitoring and registration
The CRS software program can not only be used for controlling the test procedure, reading the test values, printing a full size test- & repair report, but also for calculating the allowed seat leakage according to the international test standards.

'Stroking the trim'
The valve and its controls must work in strict harmony. The control valve reliability and overall performance is strongly influenced by the action and hysteresis of it's actuator and instrumentation. The Ventil test units for control valves are standard completed with a actuator test- & operation system for 'stroking the trim'.
