Simply put, the electric valve is to use an electric actuator to control the valve, so as to realize the opening and closing of the valve.
It can be divided into upper and lower parts, the upper part is the electric actuator, and the lower part is the valve. The action distance is larger than that of the electric valve. The switching speed of the electric gate valve can be adjusted. The structure is simple and easy to maintain. Due to the cushioning characteristics of the gas itself, it is not easy to be damaged due to jamming during the operation. However, it must have a gas source and its control system. More complicated than electric valves.
Electric shut-off valve and flanged gate valve are the same type of valve, composed of two parts: electric actuator or pneumatic actuator and shut-off valve. The difference is that its closing part is a valve body, and the valve body rotates around the center line of the valve body to realize a valve that opens and closes.
The gate valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline. Two-piece ball valve and three-piece ball valve are a new type of valve that has been widely used in recent years.
