DCL-E modulating type electric actuators are fail-safe. When control signal loses or mistaken input beyond certain range(4-20mA/2-10V), and CZPT is still on, actuator can drive valve to any position that has been set before, such as full open or full close position. Self-locking function can also prevent back driving and hunting when CZPT lose. These functions can keep whole control system safe when malfunction happens.
All actuators are rigorous tested and certified by CSA per UL and CSA standard, tested by SGS per CE and RoHS 3 standard. The self-designed high stability control packs are also certified and tested by top companies to ensure no problems during high humidity and high temperature.
