A valve assembly comprising a lower block forming a first fluid chamber configured to receive pressurized fluid from a fluid pressure source, a second fluid chamber, and a first port configured for sealed communication with a vehicle tire; a first one-way valve disposed between the first fluid chamber and the second fluid chamber so as to allow fluid communication from the first fluid chamber to the second chamber; a second one-way valve disposed between the first fluid chamber and the first port so as to allow fluid communication from the first fluid chamber to the first port; an upper block forming a third fluid chamber, a first fluid channel in fluid communication with the third fluid chamber, a relief channel in fluid communication with the third fluid chamber and a vent in fluid communication with atmosphere, wherein the relief channel and the vent each terminate at a common surface; and a diaphragm disposed between the upper block and the lower block, the diaphragm having a first side disposed against the common surface so as to substantially seal the relief channel and the vent from fluid communication, and having an opposing second side forming a wall of the second fluid chamber, such that when fluid pressure in the third fluid chamber exceeds fluid pressure in the second fluid chamber, the diaphragm may flex away from the relief channel and the vent so as to allow fluid to flow from the relief channel to the vent.
