AC380V 400Nm Fail Safe Electric Actuator

Fail safe electric actuator with emergency power off button and handwheel

Description

DCL can add standard handwheel to its electric actuators, both for common type or explosion proof type. To ensure the safety of manual handling, an emergency power off button is also available to avoid mistake operation. The power off button is on the back of actuator and very easy to reach. Sometimes, we can not confirm the actuator is powered or not, we just press the button. Commonly the handwheel is disconnect states with worm gear, when press handwheel in, it connects to worm gear and can drive the output drive and valve.

O-ring for power off button keeps whole actuator IP67 weather proof, protect against dust and water. 100% underwater sealing test during production to make sure every actuator can meet IP67 sealing grade.

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.
