GENERAL DESCRIPTION

The Bendix

RV-3

™

pressure reducing valve is a normally-

open pressure control device. The function of the RV-3

valve is to reduce system air pressure and maintain a

constant speciﬁ ed pre-set pressure below that of system

pressure. Various pressure settings can be obtained

through the use of springs and shims in combination.

The Bendix RV-3 valve has one supply port and one

delivery port. A single pipe plug is installed in the control

port and should remain in place for most applications of

the RV-3 valve. A rubber exhaust diaphragm is installed

in the end of the valve opposite the supply port. Two .28”

(7.1mm) mounting holes are cast into the valve body.

MOUNTING LOCATION

Care should be given to assure proper mounting location.

The valve should be mounted with the exhaust pointed

downward (toward the road surface), and mounted high

on the frame rail. It should be away from road spray and

debris. Unprotected or exposed exhaust ports can allow

migration of road contaminants into the valve, which may

cause accelerated wear or unintended operation.

OPERATION

The spring force exerted on the piston determines the

delivery pressure of the valve. With no air pressure present

at the supply port, the inlet valve is unseated and open while

the exhaust passage through the center of the piston is

sealed by the exhaust valve. Compressed air entering the

supply port ﬂ ows out the delivery port. Air simultaneously

ﬂ ows between the piston stem and valve body to the
