Air pressure governor valve.

Anywhere in the middle is good in my book. D 2 air governor for compressed air system m35 m54 m809 m939 m1078 etc. When the reservoir air pressure reaches the cut out setting of the governor the exhaust stem seats on the inlet exhaust valve closing the exhaust passage and then opens the inlet passage. Governor pressure increases with vehicle speed.

The unloading pressure for the typical air brake system is 120 psi but it can be higher up to 130 psi without a problem. Governor operating in conjunction with the unloading mechanism automatically controls the air pressure in the air brake or air supply system between a maximum cut out pressure and a minimum cut in pressure.

As the air pressure builds up the piston and valve move together against the resistance of the pressure setting spring.
