The HAWE CRV-23A Relief Valve is a ventable, pilot-operated balanced piston hydraulic cartridge relief valve engineered for high-flow hydraulic systems requiring stable pressure control, remote venting capability, and dependable overpressure protection. Designed for demanding mobile and industrial fluid power applications, the CRV-23A series features a balanced piston main stage with an external drain and integral 8A control cavity, delivering efficient and precise pressure regulation in large-capacity hydraulic circuits requiring advanced pilot-operated relief functionality. 

Featuring a robust T-23A cavity design, operating pressures up to 350 bar (5,076 psi), and flow capacities up to 240 L/min, these hydraulic relief valves are ideal for hydraulic power units, mobile equipment, industrial machinery, marine hydraulics, heavy-duty hydraulic manifolds, and cross-port relief applications requiring reliable unloading and remote venting control. The HAWE CRV-23A series is available with multiple minimum control pressure spring options for both low-pressure and higher pressure-drop applications and is compatible with T-8A cavity pilot controls including CRPA-8A-2D-74 and CPRB-8A-2D configurations. Designed with fast typical response times of approximately 10 ms, low leakage characteristics, and balanced piston construction for stable operation under high-flow conditions, the CRV-23A valve series helps improve hydraulic efficiency, pressure stability, and overall system reliability in demanding fluid power applications. The valve is also designed to accept maximum pressure at port 2 for cross-port relief applications when properly configured. 

Warning: Improper valve selection, pressure adjustment, installation, or hydraulic system integration may result in uncontrolled pressure conditions, hydraulic system failure, equipment damage, serious injury, or death. When used in cross-port relief applications, spool leakage should be considered during system design. Always verify system compatibility, follow manufacturer installation torque specifications, ensure proper vent, drain, and pressure settings, and adhere to all hydraulic safety procedures before operation.
