The electric gate valve simply uses 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 force 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 it is easy to maintain. During the action process, due to the buffer characteristics of the gas itself, it is not easy to be damaged due to jamming, but there must be a gas source, and its control system is also More complicated than electric valves. Electric gate valves are sensitive to response, safe and reliable, and many factories with high control requirements set up compressed air stations for pneumatic instrument control components.

The electric globe valve consists of an electric actuator and a globe 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 achieve opening and closing.

Electric ball valve is composed of electric actuator and ball valve. It is a kind of pipeline pressure element for industrial automation process control, which is usually used for remote on and off (on and off medium) control of pipeline media. The electric ball valve standard GB/T21465-2008 "Valve Terminology" is defined as a valve in which the opening and closing member (ball) is driven by the valve stem and rotates around the axis of the valve stem. It is mainly used to cut off or connect the medium in the pipeline, and can also be used for the regulation and control of the fluid. Among them, the hard-sealed V-shaped ball valve has a strong shearing force between the V-shaped ball core and the metal valve seat of hard alloy surfacing. Shear force, especially suitable for media containing fibers and tiny solid particles. Electric ball valve is divided into electric flange ball valve, electric wafer ball valve, electric welding ball valve, electric screw ball valve. According to the sealing form, it is also divided into soft-sealed electric ball valve and hard-sealed electric ball valve.

Electric butterfly valve belongs to a variety of electric valve and electric regulating valve. The main connection methods of electric butterfly valve are: flange type and wafer type; the main sealing forms of electric butterfly valve are: rubber seal and metal seal. The electric butterfly valve controls the opening and closing of the butterfly valve through the power signal.
