Specication
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 shuto valves. The indicator mounts to the bottom of the valve and visually displays
when the valve is open or closed.
Pressure Rating
10 PSI
Gases
Natural gas, propane, butane, non-
corrosive gases, and air.
Gas
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 suciently tightened. DO NOT overtighten, or
the o-ring can be damaged. An additional 1/8 to 1/4 turn
after nger-tight is typically sucient.
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shutovalvemustbede-energizedandits
gassupplyshutobeforeinstallingthevisual
indicator.
