The “position” and “way” in solenoid valves are basic terms that describe the functional characteristics of solenoid valves. However, for people who are not familiar with solenoid valves, the concepts of “position” and “way” may seem a bit abstract and difficult to understand. The following will show you a detailed understanding of “position” and “way”.
The “position” of the solenoid valve.
“Position” refers to the number of different working positions that the solenoid valve core can stay in stably. These positions represent the working status of the solenoid valve under different control signals. For example:
Two-position solenoid valve: The valve core has two stable working positions, which are usually used to control fluid flow. When the solenoid valve is not powered or not receiving an activation signal, the valve core is in the closed position, preventing the fluid from passing through. When the solenoid valve is energized or receives an activation signal, the valve core moves to the open position, allowing the fluid to pass through.
Three-position solenoid valve: The valve core has three stable working positions, which may be used to achieve fluid reversing, intermediate stop or other complex control logic. For example, in some applications, a three-position solenoid valve can switch between two flow directions and stop fluid flow at an intermediate position.
The “way” of the solenoid valve.
“Way” refers to the number of interfaces on the solenoid valve that connect to external fluid pipeline, that is the number of passages of the solenoid valve. These interfaces allow the solenoid valve to be connected to other parts of the system(such as pipes, pumps, tanks, etc.) to achieve fluid input, output or internal circulation. For example:
Two-way solenoid valve: It has two interfaces, usually one as the fluid inlet and the other as the fluid outlet. This type of solenoid valve can only control the fluid on and off, cannot change the flow direction of the fluid.
Three-way solenoid valve: It has three interfaces, which can realize the functions of fluid diversion, confluence or redirecting fluids. For example, in some applications, the three-way solenoid valve can direct the inlet fluid to one of the two outlets, or merge the two inlet fluids and direct them to one outlet.
Four-way solenoid valves and more “way” solenoid valve: which have more interfaces and can realize more complex fluid control functions, such as controlling the on/off and flow direction of multiple fluid passages at the same time.
In summary, the “position” and “way” of the solenoid valve are important parameters that describe its working characteristics and functions, which together determine the application scope and performance of the solenoid valve in the fluid control system.
Therefore, in the need of industrial automation, the reasonable selection of the “position” and “way” of the solenoid valve is conducive to the precise matching at the technical level and ensuring efficient and stable operation of the entire fluid control system.
