Continental Hydraulics are at the forefront of engineering hydraulic solutions for over 50 years-a testament to a long-standing reputation built upon your challenges and opportunities. A worldwide leader- a one-stop-shop for valves, pumps, power units and proportional products-all assembled in the USA.

The Continental Hydraulics PR*SPU valves are pilot operated pressure relief valves, for sub-plate mounting according to NFPA T3.5.1 and ISO 6264 standards.

Available in three nominal sizes, each valve incorporates a main stage poppet with a conical seal design pilot section. The pilot section is controlled via internal or external pilot (X port). A hexagonal head screw controls the pressure adjustment.

An optional solenoid valve expands the valve functionality by providing an unloading feature. In addition, two or three setting select able pressures are realized by adding a modular relief valve between the pilot stage and the solenoid valve.
