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.
