Function

Directional valves, type WMR/U6.. are mechanical directional spool valves with roller plunger. There are 2 position 3way, 2 position 4 way and 3 position 4 way valves with many versions of spool symbols, the roller/plunger can be rotated by 90°.

The valves consist basically of the housing (1), roller/plunger (2), spool (3), return springs (4), and pushing rod (5). In the unoperated condition, the spool (3) is held in the initial position by the return spring, while in operated condition, the spool (3) is pushed to the expected position by roller/plunger (2) conquering the return springs (4).

 

Cartridge throttle

The use of a throttle insert is required, when, due to given operating conditions, 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.
