WMM6 Lever Operated Valves
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, one type of actuation (roller plunger, hand lever, rotary knob), control spool, and one or two return springs.
Product Description
In de-energized state, the return springs maintain the control spool in central or starting position – if the rotary knob is actuated with a detent. The control spool is moved to the desired spool position by means of the type of actuation.
Detent Directional valves with rotary knob are generally designed with detent. Directional valves with hand lever are option-ally 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 locked, 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.
