DGMX23PPAWS40

The DGMX23PPAWS40 valve belongs to the SystemStak Modular Valves series from Vickers and regulates pressure in stacked hydraulic manifolds used in automated machinery. It is a reducing-relieving overlapped unit, so it lowers inlet pressure while also relieving excess downstream pressure to protect sensitive actuators. The subplate or manifold mounting style allows the valve to be inserted between other ISO 4401-03 interface modules without external piping, which shortens assembly time. Pressure signals reach the element through dedicated reducing line P and pilot line P function ports, providing separate paths for controlled and sensing flow. System monitoring is supported by an SAE 4 (7/16-20 UNF-2B) gauge port thread that accepts standard test fittings. Dimensional constraints are modest, with a length of 168.910 mm, a width of 71.628 mm, and a height of 59.944 mm, making the module compatible with compact power units. Actuation is pressure operated, eliminating the need for electrical coils in locations where wiring is impractical.

Flow capacity reaches 60 L/min, so the cartridge can handle medium-size circuits without creating excessive pressure loss, while the maximum working limit of 315 bar permits use on high-pressure supply lines common in industrial presses and robotics. The internal passages are designed for petroleum oils, and Viton seals maintain compatibility with these fluids at elevated temperatures. Contamination tolerance matches ISO code 19/17/14, meaning system filtration must hold particles below this level to preserve spool accuracy. Output pressure is set through a screw and locknut mechanism located at the B port end; this arrangement lets technicians dial in a specific value and secure the setting against vibration. During adjustment, the screw biases the spring stack, and once fixed it remains stable during rapid cycling. These parameters allow the DGMX23PPAWS40 to perform consistent pressure reduction and relief duties within automated hydraulic equipment.
