Dual Brake Valves

DESCRIPTION

Refer to Figures 4, 5 and 6 for item numbers referenced

in parenthesis.

The Bendix

E-8P

™

(Figure 1) and E-10P

™

(Figure 2)

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

™

valve. The use

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

™

dual brake

valve is generally used on buses, where smooth brake

applications contribute to passenger comfort.

The circuits in the E-8P

™

/E-10P

™

dual brake valves are

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.
