Accumulator charging valve, type AV02

A loading valve, also called unloading valve or constant pressure valve, provides a constant set pressure in a secondary system. Preferably in combination with an accumulator. This valve opens at 15% pressure difference from the set pressure and relieves the pump to the return. The check valve will keep port U pressurised and the coupled accumulator will absorb pressure fluctuations or sudden volume demand in the secondary system.
