BENDIX DV-2 AUTO RESERVOIR DRAIN VALVE - User Manual

®
DESCRIPTION
The DV-2
™
automatic reservoir drain valve ejects moisture
and contaminants from the reservoir in which it is connected.
It operates automatically and requires no manual assistance
or control lines from other sources.
The automatic reservoir drain valve has a die cast aluminum
body and cover and is normally mounted either in the bottom
of the reservoir using the top port of the drain valve or in the
end of an end drain reservoir using the side port of the valve.
The DV-2
™
valve is also available with a heater and thermostat
cast into the cover for vehicles operated in subfreezing
temperatures. The heated DV-2
™
valve is supplied in either
a 12 or 24 volt model and in bottom or end drain configuration.
A 1/4" male pipe adapter is supplied with all DV-2
™
drain
valves, end drain and bottom drain, both standard and heated.
This adapter should be installed directly into the reservoir.
Early versions included a filter screen in the adapter. The
filter should be discarded. Later versions may have a standard
pipe nipple instead of the adapter.
