Roemheld CLR-2952-521 | 1/2" BSPP Thread Pressure-Relief Valve

Pressure-Relief Valves

7250 psi max This safety valve is used to protect hydraulic circuits from unexpected pressure increases. Applications include disconnected pallet fixtures, where the temperature of a closed system could increase and cause hydraulic pressure to exceed acceptable operating limits. Poppet-type valve, directly controlled.

Operation

To set up initially, turn the adjustment knob on top until the desired maximum pressure is achieved. During normal operation, Pressure-Relief Valve automatically opens whenever system pressure exceeds the set pressure.

Mounting & Fluid Supply

The P port (system pressure) is the only required connection. The R port (return to tank for overflow in case of relieved pressure) is optional. Both ports are 1/2" BSPP. To adapt ports to 1/4" BSPP, order two reducing adaptors. Mount in any position, horizontal or vertical.
