Dual Brake Valve

DESCRIPTION

The E-14

™

dual brake valve is a suspended-pedal foot valve

with two separate supply and delivery circuits. The valve

provides the driver with graduated control for applying and

releasing the vehicle brakes.

The circuits in the E-14

™

dual brake valve are identified as

follows: The number one (primary) circuit is the portion of

the valve between the primary piston and the secondary

piston. The number two (secondary) circuit consists of the

area between the secondary piston and the exhaust cavity.

The supply, delivery, and exhaust ports of the E-14

™

brake

valve are identified by designations cast into the valve body

next to the port. (See Figure 1). The primary supply and

delivery ports are located in the valve’s primary body, and

the secondary supply and delivery ports are located in the

secondary body.
