Pressure Control Valves relieve, reduce, or stop system pressure. The system pressure is set by adjusting the pilot relief control valve. For the valve's pressure setting, a pressure balance on the main spindle allows the spring to hold a valve in a closed or open position (relief or reducing valves, respectively). When the system pressure working on the pilot poppet exceeds the set pressure, a pilot flow is established to the external drain.
If Elwood's standard line of Pressure Control Valves does not fit your system's requirements, please request a custom design and our team will design the valve to fit your needs!
