Pressure Relief Valves
The Cla-Val Model 750-01 is a hydraulically operated pilot actuated automatic control valve for pressure sustaining, relief and/or back pressure service. This pressure relief valve will control from no flow to full open flow without any chattering or slamming under low flow conditions. On a pump bypass system, the valve will allow flow back to the pump suction when pump discharge pressure exceeds the set point.
The 100-42 Roll Seal acts as the main valve, which consists of only two parts: a stainless steel body, and an elastomeric liner or control element. The Cla-Val CRL Pressure Relied Pilot controls the valve.
