The PP-7™ trailer supply valve provides in cab control for the tractor protection system and functions in conjunction with the park control valve. It is responsible for synchronizing the tractor and trailer parking and emergency brakes. It is essentially a combination of two non-modulating, on-off control valves in a single, compact package. Each of the four pipe tapped ports of the PP-7™ valve are identified with cast in, raised letters. The supply and control ports have 1/8 in NPTF dry seal pipe threads while the delivery and exhaust ports have 1/4 in NPTF dry seal pipe threads.
