The valve allows a driver to manually apply or release air pressure to components like parking brakes or other air-operated accessories by pulling or pushing a dashboard knob. It features a built-in automatic pressure release at 25-35 psi to prevent over-application, and has 1/4 inch NPT ports with a 1/4-28 thread for standard air line connections.
