This  unit is a pilot operated, sliding spool, screw in cartridge style, hydraulic pressure reducing/relieving valve, designated to act as a pressure-regulating device for secondary circuit.

This valve will allow flow from port 2 to port 1 until pressure in port 1 exceeds the force of the spring bias then the spool will shift and block flow from port 2 to port 1 and maintain the same pressure as the force of the spring setting regardless of the pressure at port 2. In this mode, the valve will also relieve from port 1 to port 3, regulating pressure at port 1.

WARNING – IMPROPER USE OR SELECTION OF THE PRODUCTS/EQUIPMENT OR SYSTEMS DESCRIBED CAN CAUSE PERSONAL INJURY, DEATH AND/OR PROPERTY DAMAGE. SAFETY PROCEDURES MUST BE APPLIED PRIOR TO INSTALLATION, COMMISIONING AND/OR OPERATION OF EQUIPMENT AND MACHINERY.
