Relay Emergency Valves

Relay emergency valves were used on pre-121 trailers. They apply the parking and service brakes on trailers without spring brakes. It is very important that trailers with this type of valve have no air leaks as tank pressure is used to apply the brakes when parked. If the air leaks from the system, there will be no parking brake.
