The core of the pneumatic directional control pneumatic solenoid valve lies in the combination of "through" and "position": the working position of the valve core determines "how many positions", and the number of interfaces determines "how many through". Pipeline switching is achieved through the displacement of the valve core, and its working state is visually presented by graphic symbols.

The basic concept of pneumatic directional control solenoid valves
"Through" and "position" are the core concepts of pneumatic directional control solenoid valves. Different combinations of "through" and "position" form various types of pneumatic directional control solenoid valves. The "two-position valve" and "three-position valve" we often refer to mean that the valve core of the directional control valve has two or three different working positions. The "two-way valve", "three-way valve" and "four-way valve" refer to the two, three or four interfaces on the valve body of the directional control valve that do not communicate with each other but can be connected to different oil pipes or air pipes in the system. Between these interfaces, communication can only be achieved through the displacement of the valve core and the opening and closing of the valve port.

To understand how many working states a valve has, we only need to look at how many different working positions it has, that is, "several positions". In the illustration, the square represents the valve body, and the arrow or T-line within it indicates the connection status of the oil or gas passage. Meanwhile, the number of points on the square (the points where the arrow line and the T line intersect) determines the "number of passes" of the valve.
The Role and Analysis of Graphic Symbols
In addition, graphic symbols also play a significant role in understanding the working principle and state of pneumatic directional control solenoid valves. The boxes in the symbols indicate the working position of the valve, the arrows within the boxes indicate the connected state of the oil circuit, while the symbols "┻" or "┳" indicate the disconnected state of this passage. Meanwhile, the number of interfaces connected to the outside of the box represents the "number of ways" of the valve. In the system diagram, the oil circuit or gas circuit is usually connected to the normal position of the directional control valve, which is the default position when the valve core is not subjected to external force. For a three-position valve, the median in the graphic symbol is the normal position. For a two-position valve that uses spring return, its normal position is close to the passage state within the box of the spring.
