The DGMX25PPBWS30 valve is part of the Pressure Control Valves series from Vickers. Designed for hydraulic automation, it functions as a reducing-relieving valve to maintain downstream pressure within set limits. The unit is pressure operated, so inlet pressure directly moves the spool and creates the regulating action. A screw and locknut assembly lets technicians adjust the set point on site. The model withstands a maximum pressure of 315 bar and handles flows up to 120 L/min, supporting medium-capacity circuits. It follows the ISO 4401-05 interface and mounts on either subplates or integrated manifolds, which streamlines installation in standard valve stacks. Compatibility with petroleum oils ensures straightforward use with common power-unit fluids.
The valve is built without an external drain, so return oil exits through internal passages that match the subplate pattern. System cleanliness must be kept to ISO 19/17/14 to protect the spool and seat surfaces. Viton seals are fitted to tolerate chemically aggressive additives and heat. Overall length is 208.026 mm, width is 71.628 mm, and height is 59.944 mm, dimensions that allow dense manifold layouts. The assembly operates with fluid temperatures up to 80 °C without derating. A dedicated SAE-4 O-ring boss gauge port lets maintenance staff measure secondary pressure while the machine remains in service.
