Parker pressure relief valves are designed such that when upstream pressure exceeds the closing force exerted by the spring, the lower stem opens, permitting flow through the valve.
Parker’s pilot operated relief valves are designed for continuous duty applications, featuring great stability with low pressure drop; working with pressures up to 420 bar (6000 psi) and flows up to 400 litres/minute.
The range includes the following valves series: DSDU | R06M | R4V | R4V (OBE) | R4V*P2 | R5V*P2 | R6V | R6V (OBE) | R6V (TUEV) | RPDM | RS06M | VBY*K | ZDV.
Parker direct-acting relief valves are available in several cavity sizes and are designed for continuous duty applications with pressures up to 420 bar (6000 psi) and flows up to 200 litres/minute. The range includes: EVSA | R1E02 | RE*E*T | RE*E*W | RE06M*T | RE06M*W | VB | VS series valves.
