The DGMX23PPLFWB40 is produced by Vickers as part of the SystemStak Modular Valves series and is used in hydraulic automation to maintain reduced pressure between circuits. It is pressure operated, so line pressure alone shifts the internal spool. Reducing P and Pilot P function ports provide separate passages for controlled outlet pressure and pilot supply. Installation follows the ISO 4401-03 mounting interface and uses four mounting holes to stack directly beneath directional valves. A gauge port threaded G1/8 (1/8 BSPF) allows connection of pressure gauges without adapters. Pressure is set at the A-port end by a screw-and-locknut adjuster that accepts a 4 mm (5/32 in) hex key, giving compact front-face access when the valve is fitted inside a manifold.
A locknut with a 12.7 mm (1/2 in) hex secures the chosen setting once adjustment is finished. The valve withstands operating pressures up to 315 bar and handles flow rates to 60 L/min while holding a stable reduction ratio. It is intended for systems running on petroleum oils and needs fluid cleanliness of 19/17/14 under ISO 4406 to prevent spool wear. Overall dimensions of 208.026 mm length, 71.628 mm width, and 59.944 mm height keep the module compact for stacked assemblies. These characteristics make the DGMX23PPLFWB40 a space-efficient pressure-reducing element for manifold installations in mobile or stationary hydraulic power units.
