Duplomatic DZCE*K* | explosion-proof pilot-operated proportional pressure reducing valve

Function and application

The DZCEK series are pilot-operated, three-port pressure-reducing proportional valves , designed for subplate mounting . This explosion-proof version is certified in accordance with ATEX , IECEx , or PESO standards, making it suitable for use in potentially explosive atmospheres , both in surface plants and underground mining environments . A version for low ambient temperatures , down to –40 °C , is also available, ensuring dependable operation even in extreme environmental conditions . These three-port valves reduce pressure from pressure port P to actuator port A , and allow return flow from A to T when the downstream pressure (at port A) exceeds the set value — ensuring overpressure protection . Valves are available with 12 V or 24 V supply , and can be equipped with either metric or NPT threaded ports . Cable glands are sold separately. The valve can be driven by a current-controlled power supply or via an electronic amplifier card , which must be ordered separately and installed in a separate cabinet outside the hazardous area.
