Directional spool valves type WE6... electrically operated are intended for change in direction of fluid How in a hydraulic system and thus it allows to change direction of movement of a receiver - mostly piston rod of a cylinder or hydraulic motor as well to use functions: on and off. These directional spool valves are used for subplate mounting in any position Directional spool valve is complied with the regulations of directive 2006/95/WE for the following Main elements of directional spool valve type WE6... are: housing (1), solenoids (3), control spool (2), centering springs (A) and manual overrides (5). 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 (A). The shape of the spool (control edge spacing) affects the configuration of connections among the ports: A, In case of emergency, the spool can be shifted manually by means of the override (5) - only for version with manual override. When the situation is anticipated, directional spool valve must be mounted in the way as to be available. 2-position directional spool valve without return springs with detent. The spool (2) is positioned and supported with detent (6), and its shift results from supplying voltage

2-position directional spool valve without return springs. The spool is positioned and supported with attached solenoid. There is no neutral position as the spool is not WE6...-12/...B... - directional spool valve designation like that, has throttle insert in TECHNICAL DATA ASSEMBLY AND APPLICATION REQUIREMENTS 1. Only valve working properly and suitably installed may be connected to an electric system. Only skilled workers are allowed to connect and disconnect electric system. 2. Ground connection ( i ) must be connected with protective earth wire ( PE ) in supply system according to...
