Direct operated directional spool valve with hand lever actuation Porting pattern according to DIN 24340 form A and ISO 4401 with spring return or detent, optional Actuation mechanism protected against contamination and humidity ingress Head end with actuation mechanism exchangeable without disassembly of the valve Inductive position switch and proximity sensors (contactless)

Valves type WMM are manually actuated directional spool valves. They control the start, stop and direction of a flow and basically consist of housing (1), hand lever (2), 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). The control spool (3) is actuated directly by the hand lever (2). By means of a socket and the bolt (5), it acts directly on the control spool (3) which is thereby moved from its rest position to the desired end position.

When the hand lever (2) has been reset to spool position zero, the return spring (4) pushes the control spool (3) back to its rest position again.

Type H-4WMM../F.. (with detent)

This version is a directional valve with 2 or 3 spool positions and a detent (6) which locks all spool positions.

Attention!

The switching function of the valves is independent from the filtration due to the adhesive effect. To achieve the specified admissible flows, a full flow filtration with 25 μm is recommended. The flow forces acting within the valves also influence the flow performance.

With 4-way directional valves, the specified flows are therefore valid for normal operation with 2 directions of flow (e. g. from P to A and simultaneous return flow from B to T). If there is only one direction of flow, the admissible flow may be significantly lower (e. g. if a 4-way directional valve is used as a 3-way directional valve due to blocked port A or B).
