R12 Relay Valve

Description

The R-12P relay valve is designed specifically for use on trailers and converter dollies. This 0 PSI crack and differential relay speeds up brake application signals to provide an equal or balanced pressure signal to all trailer and dolly brakes on double and triple trailer combinations. By providing the same application signal across the entire train of trailers this pilot operated relay valve aids in achieving overall vehicle brake balance and stability.
