4-way 3-position, 4-way 2-position and 3-way 2-position directional valve with mechanical, manual operation
Type WMM16, 25 and 32
Features
- Direct operating directional spool valves with mechanical, manual operation
- For sub-plates mounting
- Hand lever
- Porting pattern confirms to DIN 24 340 form A, and ISO 4401
Function and configurations
The type WMM valves are hand lever operation directional spool valves. They control the start, stop and direction of a flow.
The directional valves basically comprise of a housing (1), hand lever (2), control spool (3), as well as one or two return springs (4).
In the unoperated condition the control spool (3) is held in the neutral or its initial position by the return springs (4). The control spool (3) is actuated by the hand lever (2) via a joint and a pin. The spool is thereby moved out of its initial position into switched position.
After the hand lever(2) has been returned to the zero switched position , the spool (3) is returned to the neutral position via the return springs (4).
4WMM.../F... (With the detent)
The directional valves with one detect , 2 or 3 switched position , can be orientated at any switched position.
