- Cartridge Type Pump Unload Valve
Features
- The accumulator sense, pump unload pilot valve is used to sense pressure in an accumulator at port 1 of the valve and when the pressure at port 1 reaches the valve setting, port 2 connects to port 3 to vent a relief valve and unload the pump. This valve has a pressure difference between unloading and reset, when the pressure at port 1 drops below the valve setting value, port 2 is blocked from port 3 and the pump will come back online to recharge the accumulator.
- When applying this cartridge, a separate oil drain circuit is required to prevent unstable fluctuations in oil line back pressure.
