Duplomatic PZM3-RPA070/10N/S modular pressure reducing valve
PZM3-RPA070/10N/S is a direct operated, three-port pressure reducing valve for ISO 4401-03 / NG6 modular stacks. Configuration RPA reduces pressure in P–A. Full pressure in P–B. The regulator is on side A, using the catalogue A/B port-side designation, and the selected adjustment range is 10-70 bar.
This is a normally open, mechanically adjusted valve. Its three-port function can relieve secondary-circuit pressure surges to T. Internal drain flow returns to T; maximum T-port pressure is 10 bar. Maximum operating pressure is 350 bar, distinct from the selected adjustment range. Maximum flow is 50 l/min in controlled lines and 75 l/min in free lines.
Adjustment: S — hexagonal head adjustment screw, 17 mm spanner. Turn the adjustment screw clockwise to increase pressure. NBR seals are intended for HL/HM mineral hydraulic oils. The valve has a G1/4 pressure gauge connection and standard black phosphating.
CAD and illustrations show the matching side A S construction. External geometry is shared within the P/PA/PB or RP/RPA/RPB family; the ordering code and hydraulic configuration identify the internal circuit. Check the regulator side and reduced path when selecting a replacement.
