Proportional clamping

Our machines use proportional clamping with the help of feedback circuits to clamp the valves. This is of particular importance in case of testing by clamping between faces where the clamping load may cause deformation on the valve seat. The system calculates the appropriate clamping force corresponding to the hydro pressure at the moment and applies accordingly thus protecting your valve by ensuring there is virtually no load acted on the valve during the testing process.
