R-14H Relay Valve - Suit Kenworth

PART NO : AB8396
​

Relay valves are primarily used on long wheelbase vehicles to apply and release rear axle(s) service or parking brakes. They are air operated, graduating control valves of high capacity and fast response. Upon signal pressure from the service brake valve, they graduate, hold or release air pressure from the chambers to which they are connected. They are generally mounted close to the chambers they serve.
The R-14 relay valve incorporates an integral double check valve with a balance port connection which provides both an anti-compounding or quick exhaust feature depending upon vehicle application. The anti-compound feature is used when these valves are used to control spring actuated parking features.
