The role of solenoid hydraulic directional control valve in the hydraulic system is to achieve the commutation of the hydraulic oil circuit, sequential operation and unloading. Due to the limited thrust of the electromagnet, the electromagnetic reversing valve is used in hydraulic systems with low flow rates.
The electromagnetic reversing valve is a conversion element of the hydraulic control system and the electric control system. It is powered by push-button switches, limit switches, travel switches, pressure relays and other electrical components in the hydraulic machine to make the electromagnet energetically pull-in or power-off release, thereby directly controlling the displacement of the spool to achieve oil flow communication,cut and direction change to manipulate the actuators.
