Electro-hydraulic directional control valve uses the pressure oil of the hydraulic circuit to pull the spool and change the direction of hydraulic oil. This valve is the combination of the electrical operated directional control valve and the hydraulic operated directional control valve.
It changes the hydraulic oil direction by using the electrical operated directional control valve to control the hydraulic operated directional control valve. Electro-hydraulic directional control valve and hydraulic operated directional control valve are mainly used in hydraulic systems when electrical operated directional control valve can not afford the flow. It controls the movement of the power elements, or controls the direction of the flowing oil.
Approved by ISO9001:2008, CE, ROHS Quality System Certification, combining with advanced testing device, our products can meet the needs of cutomers' and accord with the law
