Principle and Structural Classification of 3 Way Solenoid Valves

In our daily lives,  3 way solenoid valves are used in petrochemicals, power equipment, pharmaceuticals, chemical factories, chemical analyzers, scientific instruments, and many other fields that are essential to our lives. Many systems in their control systems use 3 way solenoid valves. A 3 way solenoid valve is used to control a series of substances that need to be transmitted, and plays a crucial role in controlling them. Its structure and operation principle are as follows.

The principle of 3 way solenoid valves

Three-way solenoid valves have brought great convenience to our lives by effectively controlling the transfer of water, air, and other substances, thus preventing waste. Micro solenoid valve are believed to be used more and more widely in various fields. By controlling the valve in a timely manner, it can effectively improve work efficiency. Therefore, choosing to use 3 way solenoid valves is a wise choice, especially as they can effectively prevent the erosion of strong acids and bases, and can be used for a long time within the system. This ensures the durability and practicality of 3 way solenoid valves. In various facilities and constructions, 3 way solenoid valves will be increasingly applied. The efficient control of 3 way solenoid valves greatly reduces production costs for manufacturers, and its function of material transmission distribution greatly enhances work efficiency. It saves manpower and material resources, and the use of 3 way solenoid valves will become increasingly common in daily life.

The structural classification of 3 way solenoid valves

3 way solenoid valves mainly control the opening and closing of the valve by passing current through the coil in the solenoid valve. There are three types of structures for 3 way solenoid valves: one inlet and two outlets, two inlets and one outlet, and one inlet and one outlet. Next, we will briefly introduce the working principles of these three types of 3 way solenoid valves. The first type, one inlet and two outlets, works as follows: when the coil in the solenoid valve is energized, the solenoid valve will control the air outlet, opening one and closing the other. When the solenoid valve is powered off, the open/close sequence of the air outlet is reverse to when it was energized. The second type, two inlets and one outlet, works as follows: when the coil in the solenoid valve is energized, the solenoid valve will control the air inlet, opening one and closing the other. When the solenoid valve is powered off, the open/close sequence of the air inlet is reverse to when it was energized. The third type is special, and it is divided into two situations: one is one inlet and one outlet (normally closed), and the other is one inlet and one outlet (normally open).
