Electric Actuated Butterfly Valve 360° 24v Quarter Turn Actuator

Self-locking fail safe electric actuator with over torque protection / CSA listed

Description

DCL common series electric actuator are typically used to drive quarter turn butterfly valves, ball valves, dampers and swinging arms. On receipt of a continuous power signal, the motor runs one direction and via an all metal gear box with last stage worm gear train rotates the output drive 90°. The motor is automatically stopped by internal cams striking limit switches. On receipt of a reversing continuous signal, the motor turns in the opposite direction reversing the output drive position.

Over torque protector is optional only if accurate output torque is needed. PTC electronic heating component is also used as thermostatically controlled anti-condensation heater that will protect actuator against damage from condensation.

Actuator has been rigorous tested by CSA per UL and CSA standard. The duty rate can be over 70% for all series. The EPS system is self-calibrating which virtually eliminates "hunting" and provides an output position monitoring signal as standard.
