PC60-5/PC120-5 excavator rotary solenoid valve SD1169-24-11 203-60-56180

The working principle of excavator solenoid valve is to control the direction of compressed air by electromagnet pushing the valve core, thus controlling the opening and closing direction of pneumatic actuators. The main components of solenoid valve include coil, magnet and ejector pin. When the coil is connected with current, it will produce magnetism, and the magnet and the coil attract each other, thus pulling the ejector pin to complete the work process. After the power supply is turned off, the magnet and the ejector pin are reset, and the working process of the solenoid valve is finished. ‌

Solenoid valve is used to close and open oil circuit in hydraulic system, which is simple to operate and easy to realize remote control. According to different requirements, solenoid valves can be divided into direct-acting, step-by-step and pilot-operated types. When the direct-acting solenoid valve is energized, the electromagnetic coil generates electromagnetic force to lift the closing piece, and after the power is cut off, the spring presses the closing piece on the valve seat; The step-by-step direct-acting solenoid valve is suitable for vacuum, negative pressure, zero pressure and other environments, but its diameter is generally less than 25 mm.

In addition, solenoid valves are widely used in industrial control systems to adjust parameters such as direction, flow and speed of media. Its advantages include safety, convenience, various models and wide applications. It can cooperate with different circuits to realize the expected control and ensure the accuracy and flexibility of control.
