VALVE

DESCRIPTION

The PP valves are push-pull manually operable on-off air

control valves with an exhaust function. Most are pressure

sensitive, so that they will automatically move from the

applied to the exhaust position as supply pressure is

reduced to a certain minimum, depending on the

spring installed. The exception to this is the Bendix

PP-8

™

valve and some Bendix

PP-1

valves which

do not contain a spring. The PP-8

™

valve also has a

larger diameter shaft for button mounting so that when

installed on the same panel with other PP valves the

buttons cannot be inadvertently mixed. The PP-8

™

valve is

normally used to operate tractor spring brakes independently

from the trailer.

The Bendix

PP-5

™

valve is unique in having an auxiliary

piston in the lower cover which, upon receiving a pneumatic

signal of 18 psi or more, will cause the valve to move

from the applied to the exhaust position from a 100 psi

application.

The Bendix

RD-3

™

valve differs slightly in that it normally

remains in the exhaust position and requires a constant

manual force to hold it in the applied position.

The PP-2

™

valve has an auxiliary port which may be

plumbed into a service brake line to release the spring

brakes if a service application is made, preventing

compounding of forces on the foundation brakes.

PREVENTIVE MAINTENANCE

Important: Review the Bendix Warranty Policy before

performing any intrusive maintenance procedures. A

warranty may be voided if intrusive maintenance is

performed during the warranty period.

No two vehicles operate under identical conditions, as

a result, maintenance intervals may vary. Experience is

a valuable guide in determining the best maintenance

interval for air brake system components. At a minimum,

the PP valves should be inspected every 6 months or

1500 operating hours, whichever comes ﬁ rst, for proper

operation. Should the PP valves not meet the elements

of the operational tests noted in this document, further

investigation and service of the valve may be required.
