Governors and Components
The Governor monitors the air pressure in the supply
reservoir and operates the compressor unloading
mechanism to control whether the compressor builds
air pressure or not.
The Bendix
®
D-2
™
governor is an adjustable piston-
type valve available preset to a choice of pressure
settings.
The pressure range between the cut-in and cut-out
pressure is designed into the governor and is not
adjustable. The D-2
™
governor may be direct-mounted
to the compressor or remote-mounted as desired.
Specialized governors are available for vehicles needing
a governor adapted to abnormally high or low
temperatures, as well as a “weatherproof” model.
The D-2A
™
governor is a non-adjustable version of the
D-2
™
governor.
The D-2
™
/SV-1
™
governor module is a special
combination device used with the Bendix
®
DuraFlo
™
596 air compressor to provide the fast-rising unloader
signal needed by this compressor.
Safety Valves are used in an air brake system to
protect against excessive air pressure buildup and to
sound an audible alert. Safety valves are available in
both adjustable (e.g. the Bendix
®
ST-1
™
valve) and non-
adjustable (e.g. ST-3
™
, ST-4
™
valve) styles, in various
pressure settings, and for various port sizes. Maximum
service system air pressure allowed by government
regulation is typically 150 psi. Various safety valve
settings are used at different points in the charging and
treatment system.
Specifically designed for use in compressors, ST-4
™
safety valves are installed in an extra compressor head
discharge port, if available, or in the discharge line near
the compressor, to prevent compressor damage in the
event of discharge line blockage.
An Inlet Regulating Valve (or “IRV”) is typically used
on multi-cylinder compressors which receive their input
air supply from the pressurized side of the engine
turbocharger. The IRV, which is generally mounted to
the compressor inlet, is designed to regulate
compressor inlet pressure to 10 PSI or less. The outlet
flange of the IRV can be mounted to all Bendix
®
Tu-Flo
®
compressors except the Bendix
®
Tu-Flo
®
300
compressor. The IRV may not be used in conjunction
with single cylinder compressors.

Inlet Check Valves (or “ICV”) are used on naturally
aspirated compressors to prevent oil mist from entering
the inlet line during the unloaded cycle. The inlet check
valve either mounts to the intake side of the
compressor (and must be used in conjunction with an
inlet valve stop or inlet adapter), or may be mounted
remotely.
