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 D5X/F/... (with detent)
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.

Notice!
The specified performance limits are valid for use with two directions of flow (e. g. from P to A and simultaneous return flow from B to T).
Due to the flow forces acting within the valves, the admissible performance limit may be considerably lower with only one direction of flow (e. g. from P to A while port B is blocked)!
In such use cases, please consult us!

Notices!
Deviating from ISO 4401, port T is called TA and port T1 is called TB in this data sheet. For valves with 2 switching positions and symbols B and .B, the hand lever is installed on valve side B. The dimensions are nominal dimensions which are subject to tolerances.Related Products
