Duplomatic PDE3-350/10N-D24K1 proportional pressure relief valve
PDE3-350/10N-D24K1 is a direct operated proportional pressure relief valve for electrical pressure regulation and pilot control of two-stage hydraulic valves. The subplate mounting interface is ISO 4401-03 / CETOP 03 / NG6. This execution has a 5-350 bar pressure control range, a 24 V DC coil and NBR seals.
Maximum operating pressure at port P is 350 bar; this is distinct from the pressure control range of the selected execution. Nominal flow is 1 l/min and maximum flow is 2 l/min. Factory full-scale pressure is set at 1 l/min. At higher flow rates, full-scale pressure rises considerably; minimum controlled pressure also depends on flow. Connect T directly to tank: permissible operating backpressure is 2 bar and any T-line backpressure adds to the controlled pressure.
Use a suitable current-controlled supply or external proportional amplifier. Nominal coil current is 0.86 A. The valve incorporates a mechanical pressure-limiting feature; it has no integrated electronic controller. Compatible catalogue amplifiers include EDC-112 and EDM-M112. The K1 connector to EN 175301-803 is included in the catalogue supply. NBR seals (N) are specified for HL or HM mineral hydraulic oils according to ISO 6743-4.
IMPEX CONNECT supports international B2B sourcing of PDE3-350/10N-D24K1 for industrial hydraulic systems. Confirm the pressure range, coil voltage, seal material and mounting dimensions when selecting a replacement. Availability and delivery time are confirmed on request.
