4/3-, 4/2- or 3/2-way version
Porting pattern according to ISO 4401-05-04-0-05
Type of actuation: hand lever
Valves of type WMM are manually actuated directional spool valves.
They control the start, stop and direction of a flow.
The directional valves basically consist of housing (1), one type of actuation (2.1) (hand lever), control spool (3) and one or two return springs (4).
When de-energized, the control spool (3) is held in the central position or in the initial position by the return springs (4) (except for version "O").
The control spool (3) is moved to the desired spool position by means of the types of actuation.
Type 4WMM 10 E5X/...
Throttle insert
The use of a throttle insert is required when, due to prevailing operating conditions, flows occur during the switching processes which exceed the performance limit of the valve.
