What is the symbol for Japanese SMC solenoid valves

The Japanese SMC solenoid valve symbol refers to a schematic diagram that describes the function of the solenoid valve. It is usually used in pneumatic system design and product identification to help pneumatic system designers and solenoid valve users understand the product function. In the design process, it is often necessary to look at the air circuit diagram.

Various Japanese SMC solenoid valves appear on the drawings as corresponding pneumatic symbols, and this representation is called the solenoid valve symbol.

Meaning of Japanese SMC solenoid valve symbol

The "several positions" in front can be referred to as the number of positions depending on the working state of the valve. If there are pneumatic component symbols, it will be easier to understand. The number of squares (with arrows or T lines inside) representing the valve body on the symbol is the number of positions. And the "several connections" behind it represent the number of points on one of the squares (the points where the arrow line and T line intersect), which is the number of connections.

Detailed explanation of symbols and meanings for Japanese SMC solenoid valves

1. Use boxes to indicate the working position of the valve, and the number of boxes represents the number of "positions".

2. The arrows inside the box indicate that the oil circuit is in a connected state, but the direction of the arrows may not necessarily indicate the actual direction of fluid flow

3. The symbol "┻" or "┳" inside the box indicates that the pathway is not working.

4. The number of interfaces connected outside the box indicates how many are "connected";

5. Generally, the inlet/outlet of the valve connected to the system's oil or gas supply path is represented by the letter 'p'; The return oil/air port that connects the valve to the system's return oil/air circuit is represented by t (sometimes by o); The oil/air ports connected to the valve and actuator are represented by a, b, etc. Sometimes, l is used on graphic symbols to indicate a leaking oil port;

6. There are two or more working positions, one of which is the normal position, that is, the position where the valve core is not subjected to operating force. The middle position in the graphic symbol is the normal position of the three position valve. The two position valve with spring reset is in its normal position with the passage state within the box close to the spring. When drawing a system diagram, the oil/air circuit should generally be connected to the normal position of the directional valve.

The structure of Japanese SMC solenoid valves includes key components such as valve head coil, pilot head, valve core, and mechanical body. The valve head coil is responsible for generating the necessary electromagnetic force, and the pilot head moves under the action of the electromagnetic force. Through this series of actions, the valve core can generate displacement under the drive of the pilot head, thereby achieving precise switching of gas flow direction.

The core of Japanese SMC solenoid valves lies in the synergistic effect of their electrical and mechanical components. When the valve head is powered on, electromagnetic force will be generated, which will drive the pilot head to move. With the displacement of the pilot head, the valve core performs corresponding actions under the support of the mechanical body, ultimately achieving precise conversion of gas flow direction. This conversion process is essentially controlled by the electrical part to drive the movement of the mechanical part, thereby changing the direction of gas flow and pushing the cylinder to extend or retract.

The performance of Japanese SMC solenoid valve in power-off state is as follows:

Detailed explanation of electromagnetic valve pneumatic symbols

In the gas circuit diagram, the red box on the left represents the state when the solenoid valve loses power, with arrows indicating the direction of gas flow. The green box on the right displays the flow direction of gas when the solenoid valve is powered on. Through these symbols, we can clearly understand the working principle and gas flow of solenoid valves in the gas path.

In addition, the diagram also indicates the functions of each interface, such as the air source intake port (P), exhaust ports (R and S), and two cylinder intake ports (A and B). The combination of these symbols allows us to more intuitively understand and analyze the installation and connection methods of solenoid valves in the air circuit.

Wiring and Application of Japanese SMC Electromagnetic Valve

There are multiple options for the valve head power supply of Japanese SMC solenoid valves, including 12V, 24V, and 220V, and their power varies according to equipment requirements. For example, the power of a gas valve is usually 2W and the voltage is 24V, while the power of a hydraulic solenoid valve is 30W. When wiring, be sure to pay attention to the positive and negative poles of the power supply to avoid reversing the connection and causing the solenoid valve to malfunction.
