For the regulation of constructing HVAC dampers and valves, the ES75A, ES142 (BOTH 24 VAC AND 115VAC) and ES62A (BOTH 24 VAC/VDC AND 115VAC) can be effectively used. The Clark solutions Spring Return Electric Actuators are locked dual-point direct actuators which come with stall security and brushless DC motor engineering.
The Spring Return Electric Actuators are made to handle operations which need the damper or the valve to come back to its original and safe point. The Actuator has complete metal housing with separately adjustable twin auxiliary switches. The Spring Return Electric Actuators have a CE rating for ES62 and follow the UL, CSA norms.
