The fluid flow reversal of hydraulic transmission is mostly controlled by electrical control. The solenoid slide valve is a component that connects the electrical control system and the hydraulic system. The electrical signal sent by the electrical control system acts through the electromagnet, causing the electromagnetic slide valve to move to realize the reversal of the hydraulic oil circuit. In order to achieve various actions of hydraulic machinery.
Solenoid reversing valves are divided into AC and DC according to different power sources. The AC solenoid valve voltage is 220 volts and 380 volts, the frequency is 50 and 60 Hz, and the DC solenoid valve voltage is 24 volts or 110 volts. The commutation frequency is no more than 30 times per minute. pay. DC solenoid valves only have different electromagnets and push rods, but the structure and principle of the valve body are the same.
The wet solenoid directional valve is an improved version of the dry valve. Pressure oil is passed between the armatures of the wet solenoid and the intermediate dynamic seal is eliminated. Compared with dry valves, they have longer service life, reliable performance and no oil leakage. (The AC wet type listed in this catalog is an AC self-regulating type with a rectifier device on the electromagnet)
Note: P is the oil inlet, A and B are the oil outlets, O. O1 and O2 are oil return ports, and L is the oil drain port
