Description

DCL C model 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. Two auxiliary micro limit switches can be added to feedback passive signals of full open and full close position.

Actuators are tested to rigorous UL and CSA standards and certified by CSA. CE marked and RoHS 3.0 complied, all tested by SGS. International standard ISO5211 multi flange direct mounting plate is added without special valve bracket.
