The DGMX23PACWS40 valve belongs to the SystemStak Modular Valves series from Vickers and is installed to regulate pressure within stacked hydraulic manifolds used in automated machinery. This model is a reducing-relieving overlapped valve, allowing it to lower inlet pressure on line P and relieve excess pressure to maintain stable downstream conditions. Pressure-operated actuation shifts the spool automatically when the set level is reached, eliminating the need for electrical control. The unit withstands a maximum pressure of 315 bar and passes up to 60 L/min, defining the highest service limits for flow and pressure in the manifold. Reducing action on the P line with a pilot taken from port A gives designers flexibility when selecting the sensing location. Subplate or manifold mounting integrates the valve directly into modular stacks, while the ISO 4401-03 interface matches standard sandwich patterns for quick installation. A length of 168.910 mm keeps the assembly compact inside multistation blocks.


For commissioning, an adjuster positioned at the B-port end uses a screw and locknut so technicians can set the reduced pressure and lock the value against vibration. The SAE 4 gauge port threaded 7/16-20 UNF-2B lets a pressure gauge verify settings without additional fittings. Viton seals resist petroleum oils and elevated temperatures to maintain leak-tight performance over long service intervals. The valve is compatible with petroleum-based hydraulic fluids, and a cleanliness class of 19/17/14 identifies the maximum particle counts permitted for reliable operation. A height of 59.944 mm and width of 71.628 mm suit the spacing of SystemStak sandwiches, ensuring the valve fits within compact power units. These dimensional, sealing, and adjustment features provide precise and stable pressure regulation within automated hydraulic equipment.
