DESCRIPTION:

The Bendix

SR-1

™

spring brake valve is used in dual

or “split” air brake systems equipped with spring brake

actuators. The function of the SR-1 valve is to supply a

speciﬁ c, limited hold-off pressure to the spring brakes, and

in the event of the loss of No. 1 service air pressure, to

modulate the spring brakes through the use of the service

brake valve.

The valve has four identiﬁ ed 1/4" N.P.T.F. ports and a

diaphragm protected exhaust port. Two 5/16" diameter

holes are provided in the integral mounting bracket of the

valve body. The SR-1 valve must be mounted with the

exhaust port down toward the road surface.

OPERATION - INITIAL AIR SYSTEM CHARGE

Air ﬂ owing from the No. 1 reservoir only enters the reservoir

port of the SR-1 valve. This air remains under piston A as

system pressure builds. With No. 1 reservoir pressure

below approximately 55 P.S.I. the spring above piston A

forces it into contact with inlet and exhaust valve A causing

the exhaust to seal and the inlet to open. Refer to Figure 3.

With air system pressure above approximately 55 P.S.I. in

No. 1 & 2 service reservoirs, piston A has moved against

the force of the spring above it, allowing the inlet of valve A

to close and opening the hollow exhaust passage through

piston A. Refer to Figure 4.
