What are the operating methods of the valve electric actuator

Valve electric actuator in the field of industrial valves is also known as valve electric device, valve electric actuator with the development of industrial automation, because its power source is easy to obtain, in general, no maintenance, fast response time, can be through the feedback system to accurately control the speed, position and torque of the advantages, than pneumatic, hydraulic and other different driving methods of equipment use more common
.

In the industrial field electric valve has higher reliability and safety, when the valve can ensure performance and life, the safety and reliability of the electric valve depends on the electric actuator, so the performance and control level of the electric actuator is the comprehensive performance
of the technical level of the electric valve.

Valve electric actuator is an important equipment to achieve valve programming, automatic control and remote control, and its movement process can be controlled
by the size of the stroke, torque or axial thrust.

The operation method of the valve electric actuator is as follows: 1.
Local operation (1) The selection switch is placed in the local operation position
.

(2) Open the valve, rotate the control to the open valve command position
.

(3) Close the valve, rotate the control to the command position
of the closing valve.

(4) Screw to the "STOP" position to make the actuator stop at any position
.

2.
Manual operation The actuator needs to push the conversion handle to the manual position and release it during manual operation, at which time the hand wheel can be shaken to operate
.
