Windust Hydraulics supply the RB series balanced piston type relief valves with three pressure ranges available. The valves come with optional vent port and gauge port. The valves can be
controlled by solenoid operated directional control valves, with optional cover setting for mounting the solenoid operated directional control valve on top.
To adjust the set pressure, loosen the lock nut of the valve and turn the handle to adjust the pressure. Maintain the back pressure at the tank port as low as possible, less than 2 bar.
