Clippard's MWV-1 is a 2-way, Normally-Closed miniature whisker valve for use with bleed pressure piloted control circuits. The valve's coil spring, stainless steel whisker is easily replaceable and can be formed to different shapes. |

Bleed Pilot Control
In this circuit, the normally-open MAVO-3 is held in the closed position because the normally-closed MWV-1 creates a back pressure in the MPA-3 pilot operator. If the “whisker” of the MWV-1 is contacted it exhausts the line from the MNV-1 and the pilot actuator which allows the spring to open the MAVO-3. When the whisker is “reset” the output of the MAVO-3 will be turned off.
The MNV-1 is adjusted to a flow value that is less than the flow of the MWV-1. If the flow through the MNV-1 is too low, the MAVO-1 will have a continuous output. Conversely, if the MNV-1 is passing too much air, the MWV-1 will reach a “saturated” condition and the MAVO-3 will remain in the off position.
Note: When this circuit is initially connected to an air supply, a momentary output from the MAVO-3 will occur. Evaluate how this will affect your control.
