Protects the brake system from accessory failure. Pressure Setting on the Type 4 is not adjustable.

Used to isolate and protect one reservoir supply from another by closing at its pressure setting. Also used in rapid buildup systems where it delays the filling of auxiliary reservoirs until a preset pressure is reached in the primary reservoir.

Accepts a signal from two sources and delivers it to a common outlet, Normally used with a trailer control and foot valve where delivery pressure from either source, but not both controls the brakes.

Functions as a quick release for the emergency side of the spring brakes, while the double check valve prevents simultaneous application of the emergency side of the spring brake (anti-compounding)

Mounted on the front axle - limits front axle brake application by 50% on slippery roads. Controlled by a “flapper” switch on the dashboard. In the normal position (dry road) it will deliver full application pressure.

Automatically reduces application pressure to the front service brakes. A preset “hold-off” pressure prevents the front brakes from operating until the “hold-off” pressure is reached.

It is designed for use on a tractor only.

Combines the functions of a standard relay valve and a proportioning valve. When operating in a “bobtail” mode, the valve proportions air pressure to the lighter rear brakes.
