2. Electric motors have thermal protection function.
3. It has over torque protection function.
4. It has electrical limit function.
5. Can provide users with a remote 4-20mA feedback signal.
6. It has reliable electric braking function.

Explosion proof electric actuatorOrdering Instructions
Please indicate the model according to the model representation method. If there are special requirements, they must be specified when ordering. If not specified, please provide according to our company's regulations.
The presence of explosive gases in the environment must be specified and must comply with the explosion-proof markings specified in this manual.
Please specify the connection size standard, valve stem diameter, and extension length. If the connection size does not match this manual, you can negotiate with our company to resolve it.
Clockwise rotation of the handwheel closes the valve, otherwise it must be explained.
The thread of the thrust type valve stem nut is generally processed by the user, and our company only processes one prefabricated hole. If our company needs to process, please provide the size of the thread.
Our company can also provide electric devices with other speeds according to user requirements.
