Most of the hydraulic drive flow reversal is electrically controlled, and the electromagnetic slide valve is a component that connects the electrical control system and the hydraulic system. The electrical signal from the electrical control system is actuated by the electromagnet to move the electromagnetic spool to achieve the commutation of the hydraulic circuit. Thereby achieving various actions of the hydraulic machine.
Electromagnetic reversing valves are divided into AC and DC according to different power sources. The AC solenoid valve voltage is 110 volts, 220 volts, the frequency is 50, 60 Hz, and the DC solenoid valve voltage is 12 volts or 24 volts. The commutation frequency is no more than 30 times per minute. cross. The DC solenoid valve is only different from the electromagnet and the push rod. The structure and principle of the valve body are the same.
