Function and configurations

Directional Valves with Mechanical and Manual Operation type WMM10...L4X, are the second generation of our series 10 valves, and 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 and return spring. And they are sub-plate mounting.

Type WWM.../

These valves consist of a housing (1), hand lever(2), the control spool (3), one or two return springs (4), and a 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 hand lever (2) is pushed to right or left, the hand lever (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.

Type WWM.../F

Their operating principle is the same as the type WWM.../, and they are fitted with 2 or 3 switched positions and a detent (6), so all the switched position is fixed.

Cartridge throttle

The use of a throttle insert is required, when operating , flows can occur during the switching processes that exceed the performance limit of the valve.

These throttles are to be inserted into the P-channel of the directional valve.

Directional valves type WMM10...L4X have two handles options with different pulling direction, the detail refer to the 'Specification' and 'Unit dimensions'.
