H/ 97/9 Model 4 WE 6...6X/EG 4 N9Z45 Functional description Model 4 WE 6 E 6X/...E 6 Directional control valves Model WE 6 are solenoid operated directional spool valves. hey control the start, stop and direction of flow. hey consist of housing (1), one or two solenoids (), control spool () return spring(s) (4). Unengaged, control spool () is held centered, y means of return spring(s) (4) (except for detented spool). Control spool () is shifted y wet pin solenoids (). o guarantee satisfactory operation, ensure that the solenoid core tue is filled with oil. Cycling the valve will typically ensure core tues have filled with oil. he force of solenoid () extends push-pin (5) against control spool (), moving it left or right from a neutral position. his provides flow from to and to or to and to. When solenoid () is de-energized, control spool () returns to center y return springs (4). Manual override (6) allows activating the control spool () without electrical power. 4 () 4 Model 4 WE 6.. 6X/ O E... (only for spools, C and D) his design permits switching positions with solenoids and no detent. When the solenoids are de-energised there is no defined neutral position. Model 4 WE 6..6X/ OF E... (only for spools, C and D) his design permits switching positions with solenoids and detent. Energizing either solenoid, however, only one at a time, for approx. 0 ms is sufficient to shift spool () and maintain a position on the detent. Orifice Insert (Model 4 WE 6..6X/E /..) o limit maximum flows, orifice inserts are optionally availale. rimarily, the orifice insert is intended to prevent flow rates in excess of the maximum performance data of the valve (see page 4). he insert is installed in port, however, will fit any of the valve ports. Example: 4 WE 6E 6X/EG4ND/1 = 1. mm orifice in port. 6 R ring 9.81 x 1.5 x /8

4 R 178/06.98 Directional valve solenoid power limits, measured at ν = 190 SUS (41 mm /s) and t = 1 F (50 C) ecause of silting, the shifting function of the valves is dependent upon filtration. o otain the maximum flow values shown, full filtration of 5 µm is recommended. he flow forces acting within the valve also influence performance. In 4-way valves, the data provided is for applications with directions of flow (flow from to and an equal, simultaneous return from to, see tale). If only one direction of flow is required, for example, when a 4- way valve has one port plugged, or unalanced flows from large rod cylinders, the permissile flow in critical cases can e consideraly lower. he or spool (-way) can e used as an approximation of the limited flow performance. erformance limits measured with solenoids at operating temperature, % undervoltage and without tank port pressure.
