Self-locking electric compact actuator with high starting torque and small inertia force

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.

Actuators have been rigorous tested by CSA and certified per UL and CSA standard. In chemical and food & beverage industry, the fluid needs to be controlled very fine, so the actuator start frequency is very high. 1200 times/hour can reach world leading level and can meet requirements of above industries.
