Product Description

DCL-Ex05 dimension and parameters.pdf


Explosion proof electric actuator for Zone 1 & Division 1 / turning angle 0-360° adjustable



  • Turning angle ≤360° adjustable with electric limit switches
  • Explosion proof grade ExdIICT4 for Zone system and Group C, D T4 for Division system
  • Stainless steel visual valve position indicator with 10mm tempered glass lens
  • Hard die cast aluminum alloy enclosure to resistance to high explosive pressure inside
  • Heavy duty fully enclosed squirrel-cage asynchronous motor with fire treatment
  • Manual override with Allen handle/handwheel optional
  • Double lip skeleton oil seal and O-ring seal to ensure protection grade to IP68
  • Standard ISO 5211 direct mounting



DCL-Ex05 explosion electric actuator can set turning angle up to 340 degree. Actuators are widely used in environment with explosive gas, such as Ethylene, Ether, Ethanol etc. Cylinder stop type connection surface of each housing cover complied to UL standard flame proof gap and length. The processing quality of flame proof surface is the key process to ensure explosion grade, so the machining tolerance range must be smaller than UL standard requirements. Thus, every explosion body or cover from supplier is strictly tested by DCL before assembling.

DCL actuators use self-designed motors that is non-ventilated and full enclosed with high start torque. Due to the very compact size of actuator, the temperature rise of motor must not be high during heavy duty operation, to make sure the outer shell’s temperature will not go beyond 135℃ or 300.6F.
