The solenoid regulating valve controls the opening amount of the valve port by controlling its input voltage, so as to control the flow. When the electromagnetic control valve is used to control the flow, it is easy to realize the automation of flow control, so it is widely used in flow control instruments and equipment. In view of the fact that there is no comprehensive article about the characteristics of electromagnetic regulating valve, it is necessary to conduct in-depth research on it.

The ball of the floating ball electric ball valve can float. The structure of this ball valve is very simple and easy to operate. Because pressure is used to switch, this type of electric ball valve is not suitable for high-pressure ball valves in order to avoid damaging the sealing ring. The fixed ball electric ball valve is suitable for high pressure ball valves. The working principle of the fixed ball is to use the movement of the valve seat to work, and use the valve seat to push the seal ring onto the ball to play a sealing role. Elastic ball valve means that the ball is elastic. This ball valve is used under the condition of high pressure and high temperature.
