The spool (2) is shifted when it is moved into one of end positions by the force of solenoid (3) affecting it. The return of the spool into neutral position and centering are secured by the centering springs (4). The shape of the spool (2) (control edge spacing) causes change of the hydraulic diagram performed by the valve. Functions of ports: P P P P - supply port TTTT - oil return to the tank AAAA, BBBB - ports for a receiver (a hydraulic cylinder or a hydraulic motor) The throttle/check valves (6) allow for setting the speed of spool (2) position 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 (2) can be done manually by the button (5). The valve can be equipped with a throttling orifice (7), standard mounted in the P P P P port.

NS6 Electrically operated directional spool valve with a soft-shift function type WE6P DDDDAAAATTTTAAAA SSSSHHHHEEEEEEEETTTT ---- OOOOPPPPEEEERA RA RA RATTTTIIIIOOOON N N N MA MA MA MANUA NUA NUA NUALLLL APPLICATION DESCRIPTION OF OPERATION Electrically operated directional spool valve type WE WE WE WE6666…P …P …P …P 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 be 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 subplate mounting in any position. Directional spool valve is complied with the regulations of directive 2006/95/WE 2006/95/WE 2006/95/WE 2006/95/WE for the following voltages: •50 50 50 50 –––– 250 V 250 V 250 V 250 V for AC AC AC AC •75 75 75 75 –––– 250 V 250 V 250 V 250 V for DC DC DC DC up to 35 MPa up to 80
