™

Relay Valve

The Bendix

RE-6NC

™

(non-charging) relay emer-

gency valve is used in dolly systems and replaces the

conventional RE-6

valve. The RE-6NC

™

valve is similar

to the RE-6

valve but is designed to prevent direct ﬁ lling

of the dolly reservoir through the RE-6NC

™

valve. It is

generally used in conjunction with the PR-3

™

pressure

protection and single check valve to provide rapid dolly

brake release.

The Bendix

PR-3

™

reservoir control valve is the

combination of a Bendix

PR-4

™

pressure protection

valve and a single check valve. This valve may be used

in a variety of applications, however the most common is

in the converter dolly brake system — where it functions

to delay ﬁ lling of the reservoir until pressure in the supply

air line exceeds 75 psi — and to prevent pressure loss

due to a failure in the trailer being towed.

The Bendix

PP-1

control valve is commonly mounted

to the frame and used as a brake release valve. Pushing

in the Bendix PP-1 valve releases the dolly’s parking

brake and allows it to be moved. Since the dolly uses its

own supply air to park, once it’s moved, pulling out the

Bendix PP-1 valve button re-parks the dolly.
