DIFFERENTIAL PRESSURE RELIEF VALVE
Mounting Surface: Oilgear Standard 600Max Pressure: 2400 PSI (166 bar)
Rated Flow Rate: 1 gpm (4 l/min)
The HSDPR valve can be used as a pilor control valve to monitor differential loads.
The inlet is port 2 and the outlet is port 3. A screw is used to adjust the compression of the valve spring. If there is no pressure at pilot port 4, the valve opens when the pressure at port 1 exceeds the spring setting. If the pressure at both port 1 and 4, the valve opens when the pressure differential (between ports 1 and 4) exceeds the spring setting.
HSDPR relief valves are available with several springs. The cartridge is constructed of steel parts, and all operating parts are hardened and ground as required. The cartridge is designed for ease of service and field repair.
