Delay to write down comments upon received goods one week ago. The solenoid valve working well on our equipment, thank you a lot, friend!

—— Leo Nirva

Service is very good, BRANDO company is nice company!

—— Bob Steve

Helped me made out difficult product and also the quality is very well, I will place you my new order soon.

Solenoid valve schematic diagram and schematic diagram of solenoid valve schematic

Solenoid valves are electromagnetically controlled industrial equipment. They are the basic components for controlling fluids. They are actuators and are not limited to hydraulic and pneumatic. Used in industrial control systems to adjust the direction, flow, speed and other parameters of the media. The solenoid valve can be used with different circuits to achieve the desired control, while the precision and flexibility of the control can be guaranteed. There are many kinds of solenoid valves. Different solenoid valves play different roles in the control system. The most common ones are check valves, safety valves, directional control valves, speed control valves, etc.

 

The meaning of the graphical symbol of the solenoid valve:

1. The working position of the valve is indicated by a square. Each box represents a working position of the solenoid valve, that is, "bit". There are several boxes indicating that there are several "bits", such as a two-position three-way solenoid valve. There are two working positions.

 

2. The arrow in the box indicates that the oil circuit is in the on state, but the direction of the arrow does not necessarily indicate the actual direction of the liquid flow;

 

3. The symbol “┻” or “┳” in the box indicates that the path is unreachable;

 

4. There are several interfaces connected externally in the box, which means several "passes";

 

5. Generally, the oil inlet/air inlet connected to the oil supply or gas path of the valve is indicated by the letter p; the oil return/return port of the valve and the system return oil/gas path is t (sometimes o) Indicated; the port/port connected to the valve and the actuator is indicated by a, b, etc. Sometimes the leaking port is indicated by l on the graphical symbol;

 

6. The reversing valve has two or more working positions, one of which is the normal position, that is, the position where the spool is not subjected to the operating force. The median in the graphical symbol is the normal position of the three-position valve. The two-position valve with spring return is in its normal position with the path state in the box close to the spring. When drawing the system diagram, the oil/gas path should normally be connected to the normal position of the reversing valve.

In the front of "several digits", you have to look at this valve to have several working states, it can be said that it is a few, if there is a pneumatic component symbol, it is better understood, on the icon represents the square of the valve body (with arrows inside) Or a few T lines) are just a few. The latter "several pass" means that there are several points on one of the squares (the point where the arrow line and the T line intersect), which is a few passes.
