Hydraulic solenoid directional control valve


The hydraulic solenoid directional control valve is divided into AC and DC electromagnetic directional control valves. The AC electromagnetic reversing valve has large suction force and short commutation time, but the impact and the noise is large, and it is easy to burn when overloaded. The reliability is not as good as the DC electromagnetic reversing valve.The electromagnetic reversing valve has small starting force, long commutation time, small commutation impact, safe use and long service life. The electro-hydraulic reversing valve has smooth commutation and long commutation time, which is mainly composed of an electromagnetic reversing valve and a hydraulic reversing valve. The electromagnetic reversing valve functions as a pilot valve, and the hydraulic reversing valve functions as a main valve. A simple hydraulic system with an electromagnetic reversing valve


 General speaking,hydraulic solenoid directional control valve is for small flow, electric controlled hydraulic operated directional control valve is for high flow hydraulic system.
