DRY PIPE VALVE - 4 and 6 INCH (100 and 150 mm)
MODEL F302 (FLANGE x FLANGE) & F3021 (FLANGE x GROOVE)
The 4 and 6 inch (100 and 150 mm),
Model F302 and F3021 Dry Pipe
Valves are differential, latch type
valves used to automatically control
the flow of water into dry pipe fire pro-
tection sprinkler systems upon opera-
tion of one or more automatic sprin-
klers. The F302 and F3021 also
provide for actuation of fire alarms
upon system operation.
Both model valves have flanged inlet
connections and are identical with the
exception of the outlet connection. The
Model F302 has a flanged outlet con-
nection, whereas the Model F3021 has
a grooved outlet connection.
Dry pipe sprinkler systems are typi-
cally used in unheated warehouses,
parking garages, store windows, attic
spaces, loading docks, and similar ar-
eas exposed to freezing temperatures,
where water filled pipe cannot be util-
ized. When set for service, a dry pipe
sprinkler system is pressurized with air
(or nitrogen), and the loss of air pres-
sure through an operated automatic
sprinkler, in response to heat from a
fire, permits the dry pipe valve to open
and allow a flow of water into the sprin-
kler system piping. The differential de-
sign of the F302/F3021 is such that the
minimum air pressure in the piping is
approximately one-sixth of the static
water supply pressure, with an added
20 psi (1,4 bar) safety factor, to help
prevent a false operation that might
otherwise occur due to water supply
pressure fluctuations.
