Description Size 6 Component series 5X Maximum operating pressure 315 bar Maximum flow 60 l/min Features Direct operated directional spool valve Operating methods: Hydraulic Porting pattern according to DIN 24340 form A ( without locating hole) Porting pattern according to ISO 4401-03-02-0-05 ( with locating hole) Subplates see data sheet 45052 (separate order) Inductive position switch and proximity sensors (contactless) Product description General information Valves of type WHZ are fluidically actuated directional spool valves. They control the start, stop and direction of a flow. The directional valves basically consist of housing (1), one or two actuation elements (2) (hydraulic actuation cylinder), control spool (3) and one or two return springs (4). The ports for the control are positioned axially (6). When de-energized, the control spool (3) is held in the central position or in the initial position by the return springs (4) (except impulse spool). The control spool (3) is moved to the desired spool position by means of the actuation elements. Throttle insert The use of a throttle insert is required when due to prevailing operating conditions, flows can occur during the switching processes, which exceed the performance limit of the valve. It is inserted in channel P of the directional valve. Typ 4WH 6 E5X/... Without spring return, with detent, version .. OF /.. Directional valves with hydraulic actuation are also available as a 2-spool position valve with detent (7). If actuation elements with detent are used, each spool position can be locked. Without spring return, version .. O /.. If actuation elements without return springs and without detent are used, there is no defined spool position in the de-energized state. Type 4WP 6 C6X/OF/N...
