DZCE8G-140/40N-II/E1K11C proportional pressure reducing valve with integrated electronics
DZCE8G-140/40N-II/E1K11C is a Duplomatic NG25 proportional pressure reducing valve for industrial hydraulic pressure regulation and balancing applications. It reduces pressure from port P to working port A and permits flow from A to T when downstream pressure exceeds the electrically commanded setting. This execution controls 1-140 bar and has a maximum operating pressure of 350 bar. Catalogue maximum flow is 500 l/min; consult the performance curves for the selected pressure and operating conditions.
The on-board driver uses a 24 V DC supply and a 4-20 mA command signal (E1). The 4-20 mA monitor output represents solenoid current, not measured hydraulic pressure. Pin C is the 0 V reference for the monitor signal. K11 identifies the 6 pin + PE main connection. The mating electrical connector, mounting bolts and subplate are ordered separately.
Code II specifies internal piloting and internal drainage. Maximum permissible T-port backpressure for this configuration is 2 bar. NBR seals are intended for HL / HM mineral hydraulic oil. The mounting interface must be checked against the technical catalogue; DZCE5G and DZCE5RG have different mounting patterns.
Confirm the mounting pattern, controlled pressure range, supply voltage, command signal, pin C function and pilot/drain connections before ordering. FPM seals and other pilot/drain configurations are available on request, subject to a configuration-specific quotation. GL and GH electronics belong to separately priced executions and are not included in this standard G-series price.
