Solenoid Directional Control Valves are used for shifting oil flow direction of hydraulic circuit and for actuator starting/stopping as well as the operating direction shifting of actuator. A solenoid valve is a fluid control device that is commonly used in automatic control circuits. It consists of two parts: the control system (also known as the input circuit) and the controlled system (valve). It is actually an "automatic switch" that uses a small current and voltage electrical signal to control the continuity of the fluid line. Solenoid valves are widely used in all aspects of the automatic control field because of their low cost, small size, fast switching speed, simple wiring, low power consumption, high cost performance, and economical and practical features.
The valve body portion is enclosed in the sealing tube and is composed of a spool core, a spool sleeve, a spring base. The electromagnetic component of the solenoid valve is composed of a fixed iron core, a moving iron core, a coil, and the electromagnetic coil is directly mounted on the valve body. Thus, the valve body portion and the electromagnetic portion constitute a compact and compact assembly. There are many types of solenoid valves. Common solenoid valves include liquid solenoid valves, gas solenoid valves, oil solenoid valves, fire-fighting solenoid valves, and refrigeration solenoid valves.
