Application:
Directional valve type WMM 10 adopts plate connection, which has the advantages of small size, large flow capacity and good reliability compared with other domestic series valves. It is widely used in construction machinery, chemical machinery, light industrial machinery, locomotives and other industries.
The type WMM 10 valves are hand lever actuated directional spool valves. They control the start, stop and direction of a flow.
The directional valves basically comprise of a housing①, hand lever②, control pool ③, as well as one or two return springs④. In the unoperated condition the control spool③ is held in the neutral or its initial position by the return springs ④. The control spool③ is actuated via the hand lever ②, this acts via a joint and the pin directly onto the control spool ③. The spool is thereby moved out of its rest position into its required switched position. After the hand lever ② has been returned to the switched position zero, the spool ③ is returned to the neutral position via the return springs ④.
Type 4WMM../F.. (with detent)
These valves are either 2 or 3 position directional control valves which are fitted with a detent, which operates in all of the switched positions
