PDF05 Single‑Circuit Charging Valve
This valve is installed between the pump outlet and the relief valve. It maintains the pressure level in the accumulator oil circuit within a specified limit (opening pressure and cut‑off pressure). The switching pressure differential (the difference between opening pressure and cut‑off pressure) is approximately 20% of the cut‑off pressure. The pressure range can be adjusted according to user requirements.
