It speeds up the release of air from the service brake chambers when the driver releases the brakes, improving brake release time and reducing brake drag. The valve is commonly replaced when it sticks, leaks, or causes slow brake release. It has 3/8 inch NPT supply and delivery ports and a 0 PSI crack pressure.
