OVER-PRESSURE RELIEF VALVES >Waukesha Cherry-Burrell

Protect your pump with an external overpressure relief valve. If pump discharge Over-Pressure Relief Valves pressure exceeds the set cracking-pressure, the valve will open to a relief path. • Utilizes standard W60/W80 single seat components offering machined-from- The adjustable-spring actuator allows bar bodies, modular design, and low cost of ownership users to set the desired relief cracking • Adjustable-spring, maintenance-free actuator allows easy setting of desired pressure right at the valve by simply turning relief cracking pressure the adjustment screw. The relief pressure •...

Over-Pressure Protection on a Positive-Displacement Pump using the Adjustable-Spring Actuator Capacity Example: • Model 30 Universal PD Relief Path • Air-to-Raise Configuration Use the W61 Holding Pressure Charts in the Operation and Maintenance OUT manual or datasheet DS-1201 to select a maximum holding-pressure higher than the desired cracking pressure for a given plug size. Use the heavy-duty actuator listings i.e. 4HAR. WR61 holding pressures also listed on page 10.

Over-Pressure Protection on a Positive-Displacement Pump using the Adjustable-Spring Actuator For Free-draining, minimal dead-leg relief piping, use the WR63 valve, CD body and an Air-to-Lower, adjustable-spring actuator. If pump discharge pressure exceeds the set cracking-pressure, the valve will open and relieve the over-pressure to pump suction. Cracking pressure adjustment range from zero (fully unloaded) to maximum published hold pressure of standard, heavy-spring actuators. • Piston for full opening/by-pass. Heavy-Duty construction with (3) bearing locations and sealed, welded...

Over-Pressure Protection using a Reduced-Seat Valve and the Adjustable-Spring Actuator Reduced-Seat Valve Bodies Capacity Example: • Model 220 Universal PD • 4" (102mm) Ports, 115 gpm (26m³/hr) • Cracking Point: 170 psi (12 bar) • Cross-flow, minimal dead-leg • Air-to-lower (AL) configuration Use the W63 Holding Pressure Charts in the Operation and Maintenance manual or datasheet DS-1201 to select a maximum holding-pressure higher than the desired cracking pressure for a given plug size. Use the heavy-duty actuator listings i.e. 4HAR. WR63 holding pressures also listed on page 10. W63...
