Directional Valves with Mechanical and Manual Operation type WMM6...L6X, are direct operated spool valves
which switch the flow fluid by rotating the handle to move the spool axially. They have 2-position,3-position as
well as various spool symbols, optional detent device or return spring. And they are sub-plate mounting.
It consists of housing (1), handle (2), control spool (3), one or two return springs (4) and push rod (5).
In the unoperated condition the control spool (3) is held in the neutral or starting position by the return springs
(4). When the handle(2) is pushed to right or left, the handle(2) acts at the push rod (5) by hinge and direct
controls the spool(3), at that time, the spool(3) moves to an expected position. When the handle returns to Zero
position, spool returns to normal position by return spring. The switched position is operated by the handle.
Their operating principle is basically same as the type WWM.../, and they are fitted with 2 or 3 switched
positions and a detent, so all the switched position is fixed.
The cartridge throttle is necessary since actual flow may be larger than the performance limits of the valve
during switching process.
It is fitted in the P-line of the directional valve.
