Pilot valve

From Wikipedia, the free encyclopedia

You have new messages (last change).

A Pilot valve is a dead man's switch which requires a human operator to hold it in the mid-position and take some action if the operator takes off pressure or applies full pressure. Often (especially in heavy rail applications) this type of fail-safe braking is provided with one foot and one hand control to reduce driver fatigue by giving them the option to switch between the two.
