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

™

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 conﬁ guration. 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 ﬁ lter screen in the adapter. The ﬁ lter should

be discarded. Later versions may have a standard pipe nipple instead

of the adapter.

NOTE: If a vehicle equipped with a Bendix® DV-2™ automatic drain valve(s) is operated in subfreezing temperatures, it is recommended that a heated reservoir drain valve is installed. OPERATION Referring to Figure 1, with no air pressure in the system, the inlet and exhaust valves are closed. Upon charging the system, a slight pressure opens the inlet valve (Figure 2) which permits air and contaminants to collect in the sump.

SERVICE CHECKS IMPORTANT With system charged, make several foot valve applications and note each time an application is made, an exhaust of air occurs at the exhaust port of the drain valve. If no air comes out, push the wire stem. If no air comes out, there may be a plugged filter in the adapter which should be removed and discarded.
