1. Solenoid valve is an industrial equipment controlled by electromagnetism. It is an automatic basic element for controlling fluid. Belongs to the actuator, not limited to hydraulic and pneumatic. Used in industrial control system to adjust the direction, flow rate, speed and other parameters of medium.
2. The balance valve is a valve with special functions. There is nothing special about the valve itself, but the function and place are different. In some industries, because there is a big pressure difference or flow difference between various media (various flowable substances) in pipelines or containers, in order to reduce or balance this difference, valves are installed between the corresponding pipelines or containers to adjust the relative balance of pressure on both sides, or to achieve the balance of flow through shunt. This kind of valve is called a balance valve.
