The R-8P pressure equalizing pilot relay valve is a devicedesigned to reinforce the control signal on long wheel base towing trailers and converter dollies. Unlike a standard relay valve which typically has a 4 PSI crack pressure and similar differential between control and delivery, the R-8P valve has a 0 PSI differential. On the converter dolly and long wheel base towing trailers, the R-8P valve reinforces the service brake application signal without the differential found in standard relay valves.The 0 PSI differential of the R-8P valve assures that alltrailer and dolly brakes will receive the same strength control signal even during light brake applications. By providing a balanced pressure signal to all trailer and dolly brakes, the R-8P valve helps achieve overall vehicle brake balance and stability. The R-8P valve also helps improve brake lining wear balance on combination vehicles by causing even the most distant brake to contribute it's share of braking effort.
