What are the differences between different types of fluid solenoid valves?

Different types of fluid solenoid valves (such as two-position two-way, two-position three-way, three-position five-way) have significant differences in functions and applications. The two-position two-way solenoid valve has two states, namely open and closed, and has only two ports, one inlet and one outlet. They are used for simple switch control, suitable for through-flow control of liquids and gases. They are commonly used in water treatment systems, pneumatic systems and various industrial automation equipment. Because of their simple structure and low cost, they are widely used in situations that require on-off control. .

The two-position three-way solenoid valve also has two states (on and off), but has three ports, usually one inlet and two outlets, for selectively controlling the flow direction of the fluid. For example, when one outlet is closed, fluid flows to the other outlet. This kind of valve is often used for single-acting cylinder control in pneumatic systems because it can achieve simple switching of fluid flow direction and is suitable for applications that require switching of fluid paths.

The three-position five-way solenoid valve has three states (open, closed and neutral) and five ports, usually two inlets, two outlets and one exhaust port. It is widely used in pneumatic systems, especially the control of double-acting cylinders. In the neutral position, this valve can achieve different functional configurations, such as venting, maintaining pressure, or disconnecting all ports. Due to its high flexibility and complex control capabilities, the 5/3-way solenoid valve is suitable for applications requiring precise control and multi-functional configuration.
