The SUN RBAE-LWN is a pilot-operated, balanced piston relief valve designed for hydraulic systems. As a screw-in cartridge valve, it is engineered to limit the pressure in a circuit by diverting flow from port 1 to port 2 when the set pressure is reached. Its balanced piston design ensures that the relief setting is virtually unaffected by back-pressure at the outlet port. This valve is known for its fast response time, low hysteresis, stable pressure control, and overall reliability in demanding applications.
