Product Description

Position transmitter equipped anti-explosion electric actuator / output 4-20mA signal



  • Self-developed position transmitter to output 4-20mA signal of valve position
  • High quality alloy steel sleeve and ball bearings, all metal gear drive, Self-locking bronze alloy worm gear
  • Heavy duty motor with 70% duty cycle for severe applications
  • High pressure die cast aluminum alloy enclosure with IP68 and type 4X sealing grade
  • Manual override with wrench or handwheel
  • ISO5211 direct installation
  • CSA certified per UL and CSA standard/CE marked/RoHS 3.0/ATEX/SIL 3



DCL F model explosion proof electric actuator is equipped with self-developed position transmitter to output 4-20mA analog signal of valve position. It can be widely used in 3-point floating control system to drive quarter turn butterfly valves, ball valves or dampers. This kind of control system can obtain continuous analog signal of valve position signal to decide when to cut off power or reverse power direction.

The duty cycle of actuator is 70% or higher, For on-off type, actuator can keep working for 15mins without stop. For modulating type, actuator can start 1200times/hour. Whole full range open & close life cycle is over 10000 times and 200000 times start up. Even in full heavy duty applications, the motor temperature rise can meet enclosures’ T4 (130℃) requirements, to avoid to ignite certain flammable gases outside.
