The electric valve is simply to use the 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 an electric actuator and the lower part is a valve. The action force distance is larger than that of the electric valve. The switching speed of the electric gate valve can be adjusted, with simple structure and easy maintenance. During the action process, it is not easy to be damaged due to jamming due to the buffer characteristics of the gas itself, but there must be a gas source, and its control system is also more complex than that of the electric valve. The electric gate valve is sensitive, safe and reliable. Many factories with high control requirements set up compressed air stations for pneumatic instrument control elements. Electric is a device that needs electricity and can control its flow.
