Parker unloading valves automatically charge and maintain a specific pressure range within accumulators by loading and unloading pump flow.
The range includes:
R4U series | subplate mounted unloading valves used to unload a circuit at low pressure
VP120 series | sectional, pressure-compensated, load-sensing directional control valves for mobile machines
UR*E and US*E series | unloading valves with mechanical pilot stage and a slip-in cartridge main stage used to unload a circuit at low pressure. The US*E series is vented by electrical operation.
R5U series | pilot-operated pressure unloading valves, particularly suitable for unloading a circuit at low pressure. SAE flanges allow direct mounting to achieve a very compact design
UR06M and US06M series | 2-way slip-in cartridge valves with unloading function. Series UR06M are for subplate mounting and US06M for sandwich plate mounting.
Our hydraulic product portfolio is constantly growing with new parts added daily, but we still only show a small selection of we supply.
