Function and configurations

Directional valves type WMD... are mechanical, manual operated directional spool valves. They control the start, stop and direction of a flow. The rotary knob (2) operates (2×90°) the spool (1), the screw type rotation transforms into axial movement and direct acts on the spool (1). Then the spool (1) moves to the end position and gets the opening position as required.

Actual switch position of spool (1) can be controlled with rotary knob (2). All the switch positions can be orientated by locating device.

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.
