1 Electrically operated directional spool valve with a soft-shift function type WE6 NS6 up to 35 Ma up to 80 dm 3/min D SHEE - OER RION MNU NUL WK LICION Electrically operated directional spool valve type WE6 is intended for changing the direction of fluid flow in a hydraulic system allowing change of the direction of movement of the receiver usually a piston rod of a cylinder or a hydraulic motor and also performance of states: start, stop. It can e used to eliminate arising when overriding adverse dynamic phenomena as a less expensive alternative to proportionally controlled directional control valve with electronic controller. It is adjusted for suplate mounting in any pos. Directional spool valve is complied with the regulations of directive 006/95/WE for the following voltages: V for C V for DC DESCRIION OF OERION 4WE6 E - 3/G4NZ4 X-X X a X 7 Main elements of directional spool valve type WE6 are: housing (1), control spool (), solenoids (3), centering springs (4), manual overrides (5) and soft-shift throttle/check valves (6). he spool () is shifted when it is moved into one of end poss y the force of solenoid (3) affecting it. he return of the spool into neutral pos and centering are secured y the centering springs (4). he shape of the spool () (control edge spacing) causes change of the hydraulic diagram performed y the valve. Functions of ports: - supply port - oil return to the tank, - ports for a receiver (a hydraulic cylinder or a hydraulic motor) he throttle/check valves (6) allow for setting the speed of spool () pos change, independently, at turning on and turning off the solenoids (3) and in the effect, eliminating dynamic states (pressure peaks and flow peaks), causing overload of the receiver and the hydraulic system, as well as noise generation. In case of power failure, the shift of the spool () can e done manually y the utton (5). he valve can e equipped with a throttling orifice (7), standard mounted in the port. NOE: rior r to start of the operation of the valve, it is necessary to thoroughly vent the soft shift valves (6) ports and solenoid chamers (5) - see page p : requirements for installation and operation - point 8. ype WE6s3-1 - WK

Only fully functional and operational valve, properly connected to electrical installation must e used. Connecting or disconnecting the valve to an electrical installation must only e carried out y qualified personnel.. Ground connection ( ) must e connected with protective earth wire (E ) in supply system according to appropriate instructions. 3. Solenoid plug shall precisely adhere to socket and shall e secured with thread olt screwed in securely in a place. It is foridden to operate the valve if the tightness and suitale clamp of cale in the plug gland are not ensured. 4. During the period of operation must e kept fluid viscosity acc. to requirements defined in this Data Sheet - Operation Manual 5. In order to ensure failure free and safe operation the following must e checked: cond of the electrical connection proper working of the valve cleanliness of the hydraulic fluid 6. Due to heating of electromagnet solenoid coils to high temp., the valve shall e placed in such way to eliminate the risk of accidental contact with solenoid or valve housing during operation or to apply suitale covers acc. to N - EN ISO and N - EN In order to ensure tightness of the directional valve lock, one should take care of dimension of sealing rings,, tightening torques and valve operation parameters given in this Data Sheet - Operation Manual 8. rior to first use of the valve, one should vent the soft shift valves. It is recommended to set the valve in such a way that the valve settings were directed upwards. In order to provide a thorough venting, it is recommended to unscrew the soft shift valves, immerse the ports in oil that is used and override the valve without any load. his process should e repeated until the ports are full, and then, the valves can e screwed. fter venting, set the valves setting to achieve optimal operation of the valve. 9. person that operates the valve must e thoroughly familiar with this Data Sheet - Operation Manual.
