Full Product Description

Parker’s DWV is designed to eliminate or minimize shock, surge, or overload conditions on hydraulic equipment. The need for anti-cavitation checks is eliminated. Relieved oil is directed to the opposite side of the relief (crossover) preventing cylinder or motor cavitation. It is recommended that the DWV be installed as close to the actuator as practical for optimal performance.

The pressure setting for the DWV is either screw or shim adjusted and is typically ordered preset to one of 4 default settings. Each of the 4 setting options have a usable adjustment range. Custom settings are available via contacting factory.
