Description
DCL explosion proof electric actuators are widely used for chemical, power plant, winery, oil & gas and petroleum etc. Actuator uses cylinder stop type flameproof surface with very high precise machining. The connection part between body and covers are complied to ATEX, IECEx, UL and CSA standard required length and gap. ExdIICT4 grade for ATEX, IECEx and Zone system, Group C, D T4 for Division system used in USA.
Middle position is optional for that valve need to be stopped in 3 specific positions. Two dry contact feedback for full open and full close position. Actuator can be installed 360° any angle on the pipe or other devices. Valve stays at last known position when actuator’s power lose. Dehumidify heater is optional to protect actuator against condensation.
