Abstract
A method of decreasing tire pressure includes opening a wheel valve () to allow pressurized air from a tire () to be directed to a first valve assembly () and to atmosphere. A target pressure is selected for a fluid control conduit (). The fluid conduit () is in fluid communication with the first valve assembly () and a second or control valve assembly (). The pressure in the fluid conduit () is measured. If the measured pressure is greater than the target pressure, then the second valve assembly () is de-energized. If the measured pressure is less than the target pressure, then the second valve assembly () is energized. A valve () prone to leak under very low temperatures may be subjected to repeated cycles of pressure application and pressure release in order to form a fluid-tight seal.
