Product Description

HAWE CMV, CMVZ, CMVX Proportional Pressure Relief Valves

The HAWE CMV, CMVZ, and CMVX series are direct-acting proportional pressure relief valves designed to limit the pressure within a hydraulic system. The pressure setting is continuously adjustable in proportion to the electric current supplied to the solenoid. This allows for precise, remote control over system pressure. The CMV type is a screw-in cartridge, the CMVZ is housed for in-line pipe connection, and the CMVX is designed for manifold mounting. These valves are characterized by their compact design, rapid response times, and stable performance, making them suitable for a wide range of industrial and mobile hydraulic applications.
