CL Ex – Electro-mechanical part-turn actuator for Ex-Zone 1

CL Ex

Electro-mechanical actuator for explosive areas

Classic drive technology in a sturdy housing with compact dimensions. ARIS actuators of the CL Ex series are designed for industrial use in zone 1 hazardous areas. They are used for the actuation of regulating and shut-off devices, e.g. flaps, valves, ball valves, dosing pumps etc., and offer a high safety level. The classic drive technology of the CL with synchronous or direct current motor allows a simple replacement of actuators in existing circuits and systems. The large number of mounting holes according to ISO 5211 and a change-over shaft system ensure a simple construction on all standard fittings without costly brackets. The drives of Zone 1 are characterized by a high level of intrinsic safety and operational safety.
