Specification
Visual Indicator The Visual Indicator (VI) is for use with the DUNGS SV (DLE), MV (D) (DLE), DMV-D(LE), and DMV-
ZRD(LE) series of shutoff valves. The indicator mounts to the bottom of the valve and visually displays
when the valve is open or closed.

Mounting
1. Remove the plug and the o-ring on the bottom of the valve
with a 5 mm hex key wrench.
2. Insert the Visual Indicator and its o-ring; using a 5/8"
(16 mm) open end wrench, turn clockwise until the Visual
Indicator is sufficiently tightened. DO NOT overtighten, or
the o-ring can be damaged. An additional 1/8 to 1/4 turn
after finger-tight is typically sufficient.
3. Be certain that the valve area where the stickers will be
placed is clean before applying the stickers. Install the two
aluminum adhesive-backed stickers (one on each side) of
the valve body so the operator can refer to either of them
while viewing the indicator.
4. Before putting the valve into service, test the indicator by
opening and closing the valve to visually verify the indicator
is working properly.
5. Apply a soapy water solution between the indicator and
the valve body to verify that no leakage occurs.
The shutoff valve must be de-energized and its
gas supply shut off before installing the visual
indicator.
Function
The valve position is indicated through the clear plastic cover.

Reducing the main flow adjustment may limit the
ability of the VI to indicate the opened position of
the valve. At least 5/32" (3.5 mm) of stroke is required
for the visual indicator to indicate an opened valve.
