®
The Bendix
E-8P
(Figure 1) and E-10P
dual brake valves are fl oor mounted, treadle operated
type brake valves with two separate supply and delivery
circuits for service (primary and secondary) braking, which
provides the driver with a graduated control for applying and
releasing the vehicle brakes.
The E-10P
dual brake valve (Figure 2) is similar to the
E-8P
dual brake valve except that a metal coil spring
(5) housed in an upper body assembly replaces the
rubber spring (27) used in the E-8P
of a metal coil spring (and the upper body assem-
bly) provides greater treadle travel and, therefore,
provides the driver with a less sensitive "feel" when
making a brake application. The E-10P

valve is generally used on buses, where smooth brake
applications contribute to passenger comfort.
The circuits in the E-8P
identifi ed as follows: The No. 1 or primary circuit is that
portion of the valve between the spring seat which contacts
the plunger and the relay piston; the No. 2 or secondary
circuit is that portion between the relay piston and the
exhaust cavity.
The primary circuit of the valve is similar in operation to a
standard single circuit air brake valve and under normal
operating conditions the secondary circuit is similar in
operation to a relay valve.
Both primary and secondary circuits of the brake valve use
a common exhaust protected by an exhaust diaphragm.
