The BP-R1 bobtail proportioning relay valve is a combination of two valves in a single housing.
The lower portion contains a "standard" service brake relay valve, which functions as a relay
station to speed up brake application and release. The upper portion houses a brake proportioning
valve which reduces normal service brake application pressure when the tractor is not towing a
trailer (bobtail operation). The control port on the BP-R1 is connected to the Trailer Supply
valve delivery and signals bobtail operation.
