Product Description

Explosion proof DC rotary electric actuator / ExdⅡB T4 grade for Zone 1 and Division 1



  • Modulating type powered by 24VDC, quarter turn operation
  • Torque can be precisely setting within a certain range
  • Heavy duty DC brush motor with lower temperature rise, longer life, provide high start torque and very small inertia force
  • Torque test control and over torque protection by current
  • PTC electronic heating component to prevent condensation in actuator
  • Compact smart resin plastic packaged proportional control pack installed
  • IP 68 watertight robust aluminum alloy enclosure, protection against dust and water
  • Self-locking worm gear train, no additional brake needed
  • UL standard for Zone and Division System/ATEX/CE marked/RoHS 3 complied



DCL-Ex10GE/Ex40GE are 24VDC power motorized electric actuator. Full enclosed DC brush motor with flameproof surface ensure sparks will not go to another cavity. Fully potted controller to help protect the electronics from vibration and moisture. Cylinder stop type connection surfaces with flame proof gap and length comply to ATEX, UL and CSA standard. Valve position indicator is covered with 10mm tempered glass that can keep strength in extra high and extra low temperature to ensure clear vision even when fire happens. Anti-condensation heater is optional to protect actuator against moist. Enclosures and covers are 100% tested by DCL before acceptable from suppliers to ensure machining precise.

DCL explosion proof electric actuators are widely used for explosive gases environment. High temperature may ignite the flammable gases out of actuator. T4 grade requires the highest enclosure outside surface’s temperature must be less than 135℃(300F), in whatever conditions. Considering a buffer for errors may happen, the temperature set for motor power down is 125℃(282F). PTC overheat protector is embedded in the motor winding-trips, where is the highest temperature rise part of whole actuator, instead of out of motor, to 100% ensure outer surface temperature will not go beyond required T4 grade.

Explosion proof electric actuators are in process of CSA tests and will be certified by CSA in Q3 2020. CE/ATEX/RoHS 3.0 have been tested and complied.
