The DGMX25PPFHB30 pressure-reducing valve belongs to the SystemStak Modular Valves series manufactured by Vickers and is used to maintain controlled pressure levels in hydraulic automation stacks. Its two-stage spool design stabilizes downstream pressure even when flow fluctuates. The valve conforms to CETOP size 5 so it fits common manifold envelopes, and it attaches through an ISO 4401-AC-05-4-A (NFPA D05) interface; 6.90 mm mounting holes provide the bolt clearance needed for secure stacking. Pressure is set with a knob identified as adjustment device H, allowing quick manual tuning. An internal drain routes pilot oil back into the manifold without an external line, and a G 1/8 (1/8 BSPF) gage port accepts a test gauge for visual pressure checks. The assembly weighs 3.5 kg (7.7 lb), enabling one-person handling during installation.
The valve passes up to 120 l/min (32 US gpm) while withstanding inlet pressures to 315 bar (4500 psi), making it suitable for medium-to-high power circuits. It operates at fluid temperatures to 80 °C (180 °F) to match typical industrial oil limits. The reduced outlet pressure can be adjusted from 8.5 bar to 200 bar to match actuator requirements and prevent overloading. Pilot control is taken from the P pressure port, and the same port is regulated by the main spool to simplify piping. Excess flow from the reducing stage is diverted through relief port TB, keeping return flow separate from the regulated line. These capabilities let the DGMX25PPFHB30 deliver compact, reliable pressure management in stacked hydraulic manifolds.
