The basic structure of a refrigeration valve consists of a coil and a movable iron core located in the coil. When the coil is energized, the cooling valve generates a magnetic field to drive the iron core, and the valve is opened by the movement of the iron core. The reset action of the valve is completed by the gravity of the valve core and the elastic force of the spring mounted on the top of the valve.
In addition to the advantages of a soft seal gate valve, the fire gate valve can more intuitively display the opening degree of the valve, so that the opening degree of the valve can be judged at a farther distance.
In the valve engineering of power plant chemical plants, the types of valves equipped with valve electric devices for operation mainly include gate valves, globe valves, butterfly valves and ball valves.
