Description

DCL C model explosion proof electric actuator is equipped with potentiometer to feedback continuous resistance signal. Always used for some control system that can transfer resistance signal to current signal or voltage signal outside actuator. The resistance value output is proportional to valve position, 500Ω and 1000Ω range are optional.

Actuator can be used in 90% explosive gas except mining with ExdIICT4 and Group C, D T4 grade. Patented integral design of motor/housing makes the actuators very compact and light weighted. Actuators are ATEX marked and SIL 3 certified, and have got the CSA certificate.
