Description

DCL fire safe compact electric actuators can be motorized by multi grade electric power, including 24VDC, 24VAC, 110VAC, 220VAC, 380VAC, 440VAC etc. Integral motor/housing/control pack design make DCL explosion proof electric actuators become the smallest actuators for certain torque range. The machining accuracy of enclosure is 100% inspected and perfectly controlled by DCL to ensure no dangerous when explosion happen. Every actuator suffers underwater test to make sure the sealing grade to IP68 and NEMA7.

Actuators are under strict tests hold by CSA per UL and CSA standard. CSA certification has obtained both for Zone and Division system in 2022. ATEX certified by EU authorized certification body.
