The Ratio Feature is considered a benefit in hard stop
situations and refers to the relationship between the
control air pressure to the valve and the delivered air
pressure from the valve to the service brake chambers.
During normal stopping, a 1:1 ratio exists between the
control and delivered air pressures. In a hard stop, the
ratio momentarily changes to 1:1.5 until valve lap-off
occurs and the ratio is restored. This change takes place
in less than 1/100th of a second.
