Established through a strategic partnership between the Chinese and German governments in 1979, Huade has been an outstanding brand in Chinese hydraulic industry. Huade® directional spool valve type 4WE 6 E is an affordable alternative to the same model offered by Rexroth. Huade puts great stress on the quality to ensure that every directional valve has superior performance. The solenoid directional valve series has passed CE certification. This type directional valve sells well. The valves will be packed in standard cartons with anti-counterfeiting labels. The factory has passed the three major system certifications of quality management, environmental management, and occupational health and safety management. Huade® hydraulic valves are widely used in engineering and construction machinery, metallurgy, machine tools, environmental protection, shipbuilding, aerospace, rail transit, petroleum and petrochemical, military industry and other fields.

Application:
4WE 6 E is solenoid operated directional spool valve. It controls the start, stop and direction of a fluid.
Essentially the directional control valves consist of housing (1),one or two solenoids (2), the control spool(3), and one or two return springs (4). In the de-energized condition the control spool (3)is held in the neutral or initial position by means of return springs (4) (except for impulse spools).The control spool (3)is actuated via wet pin solenoids (2). The force of the solenoids (2)acts via the plunger (5)on the control spool (3)and pushes this from its neutral position to the required end position.This gives free-flow from P to A and B to T or P to B and A to T.
When solenoid (2) is de-energized, the control spool (3) is returned to its neutral position by means of the return springs (4).
An optional hand override (6), allows movement of the control spool (3) without energising the solenoid.
