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.
