Description Size 6 Component series 6X Maximum operating pressure 315 bar Maximum flow 60 l/min Features 4/3-, 4/2- or 3/2-way version Porting pattern according to DIN 24340 form A ( without locating hole) Porting pattern according to ISO 4401-03-02-0-05 ( with locating hole) Type of actuation: Roller plunger Inductive position switch and proximity sensors (contactless) Product description Type WM.. valves are mechanical, manually actuated directional spool valves. They control the start, stop and direction of a flow. Directional valves basically consist of housing (1), one type of actuation (2) (roller plunger), control spool (3) and one or two return springs (4). In de-energized state, the return springs (4) maintain the control spool (3) in central or starting position - if the rotary knob is actuated with a detent. The control spool (3) is moved to the desired spool position by means of the type of actuation (2). Detent Directional valves with rotary knob are generally designed with detent. Directional valves with hand lever are optionally available as 2 or 3 position valves with detent. Directional valves with roller plunger are generally designed without detent. If types of actuation with detent are used, each spool position can be fixed, depending on the valve type. 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. Type 4WM. 6 ..5X/..B..
