How does the electric gate valve actuator switch the valve? Can the electric valve actuator manually open or close
With the development of industrial automation, electric valve actuators available power sources, generally do not need to maintain, fast response time, can control the speed, position and torque feedback systems, than different drive mode such as pneumatic, hydraulic equipment, more frequently used many users problems encountered in the use process, such as: electric switch valve gate valve actuators? Can the electric valve actuator be manually opened or closed? Like Valve answers for you!
A, how to switch the valve electric gate valve actuator
The operation mode of the valve electric actuator is as follows:
1. Local operations
(1) Place the selection switch in the local operation position.
(2) Open the valve and rotate the control to the command position of the open valve.
(3) Close the valve and rotate the control to reverse the critical valve command position.
(4) Rotate to STOP position, so that the actuator stops at any position.
2. Manual operation
For manual operation, the actuator needs to push the conversion handle to the manual position, then release it and shake the handwheel for operation.
Two, the electric valve actuator can be manually opened or not closed
Can, basically any open a are equipped with manual devices, electric valve actuation moment is larger than normal valve, electric valve switching speed can be adjusted, simple structure, easy maintenance, can be used to control air, water, steam, all kinds of corrosive medium, mud, oil, liquid metal and radioactive medium, etc. All types of fluid flow. Because of the buffer characteristics of the gas itself in the process of action, it is not easy to be stuck and damaged, but there must be a gas source, and its control system is more complex than the electric valve
General electric control valve has three lines, one of the public lines and two are on and off, from this phenomenon, there is a problem with the control loop, perhaps the electric valve itself or a line problem somewhere, which can only be carefully to find the line.
There is a handle on the valve electric actuator. When manual operation is needed, first pull the handle. After it is in place, turn the handwheel.
Electric valve action distance than ordinary valve, electric valve switch speed can be adjusted, simple structure, easy maintenance, can be used to control the flow of air, water, steam, a variety of corrosive media, mud, oil, liquid metal and radioactive media and other types of fluid.
