Product Overview

As a leading manufacturer in China's hydraulic industry, Huade cooperated with Rexroth twice from 1979. Huade® 4WE 6 Y directional spool valve is widely used in various industrial environments.  It can replace the same model offered by Rexroth.  It is wildly sold in China and in foreign countries. Huade puts great stress on the quality to ensure that every directional valve has superior performance. Huade has 750 advanced production equipment imported from all over the world. The solenoid directional valve series has passed CE certification. The factory passed ISO9001, ISO14001, and ISO45001. Huade® hydraulic solenoid valves are widely used in the military industry and other fields in China due to stable performance.

Key Features

  • Direct solenoid actuated directional spool valve high performance version
  • Wet pin DC or AC solenoids with removable coil
  • Solenoid coil can be rotated through 90°
  • Electrical connections either as individual or central connections
  • It is not necessary to open the pressure tight chamber when changing the coil
  • Hand override, optional
  • Porting pattern to Din 24 340 form A, ISO 4401 and CETOP - RP 121H

Industrial Applications

  • Directional valves of type 4WE 6 Y are solenoid operated directional spool valves. They control the start, stop and direction of a fluid.
  • Essentially the directional control valves 4WE 6 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.
