DESCRIPTION
The Bendix
®
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 drain 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 a 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.
