We used in the production of solenoid valves in two of three links, two four-way, two of five such. First talk about the two meanings: for the solenoid valve is charged and the loss of electricity, for the control valve is on and off. Oxygen plant instru mentation and control system, two way single coil solenoid valve  with the largest in production can be used to connect or disconnect the gas source, in order to switch the gas pneumatic control film head. With the spring pressure by the valve body, flange solenoid valve  cover, electromagnetic components, spring, and seal the structure components, moving core at the bottom of the seal block the body inlet closed. Energized, solenoid pull action with spring core the upper seal block the exhaust port closed, the airflow from the inlet into the first film, play a controlling role. When the loss of electricity, the electromagnetic force disappears, the moving core in the spring force to leave the fixed iron core, moving down the exhaust port to open, blocking the inlet, the first film airflow through the exhaust port, the diaphragm rec overy original position.
