FEATURES AND BENEFITS
FEATURES
AMERICAN Flow Control’s Series 2500 Ductile Iron
Resilient Wedge Gate Valves are suitable for use in
drinking water, sewage and re protection systems.
The Series 2500 has a rated working pressure of 250
psig and seal with zero leakage. The design employs
a clear unobstructed waterway.
•The2500hasnodiscinwaterwaytorestrictow
or to increase pumping costs.
• The clear waterway allows passage of pigging
devices.
• Internal parts can be serviced without cutting
the valve out of the pipeline.
• The 250 psig rating allows working pressure to be in-
creased above the 150 psig pressure rating found
onmostbutteryvalves.
• The 2500 closes with zero leakage. No more time
consuming testing to determine allowable leakage
rate.
• No pocket in bottom of valve to collect sediment
or trap debris.
• Lower torque requirements to operate valve.
• 250 psig pressure rating compared to the 200 psig
rating found on most double disc gate valves.
• Fusion bonded epoxy coated inside and out.
• Lower total valve weight.
•250 psig rated working pressure.
• Ductile iron body, bonnet, wedge, operating nut
andstu󰀩ngbox.
• Triple O-ring stem seals.
• Thrust washers.
• Fusion bonded epoxy coating.
• 100% bottle tight closure.
• Rubber encapsulated wedge.
• Flat features on valve body allows the valve to
stand upright for storage or, during installation.
• Optional geared actuators.
•2in.–66in.valvesareCertiedtoNSF/ANSI
Standard 61 and NSF/ANSI 372.

GATE VALVES
SERIES 2500 RESILIENT WEDGE GATE VALVE
STANDARD FEATURES
BENEFITS
DUCTILE IRON CONSTRUCTION
The ductile iron body and bonnet provide superior strength
and allow a pressure rating of 250 psig. The strength of
ductile iron is double that provided by gray iron. This added
strength and higher pressure rating is provided in a compact,
lighter design.
FUSION BONDED EPOXY COATING
The Series 2500 valve is epoxy coated both on the
interior as well as the exterior of the valve. The fusion bonded
coating is applied after the valve body is shot blasted clean.
The coating is applied to all ferrous surfaces so that even the
bolt holes and body-to-bonnet ange surfaces are epoxy
coated.
THRUST WASHERS
Thrust washers are located above and below the stem collar
ensuring trouble-free operation of the valve.
DUCTILE IRON LIFTING LUGS
Thestu󰀩ngboxisconstructedofhighstrengthductileiron
with integral lifting lugs on most sizes. Lifting lugs allow the
valve to be lifted safely, without risk of the valve falling or
damaging the valve by lifting from the operating nut.
TRIPLE O-RING STEM SEALS
This valve features triple O-ring stem seals. Two O-rings
are located above the thrust collar and one O-ring is located
below the thrust collar. The O-ring directly above and
below the stem collar provide a sealed lubrication chamber.
This feature assures the ease of operation for long periods of
time without the need for constant maintenance required for
other designs. The upper O-ring acts as a shield, sealing the
stemfromdirtandgritthatmightotherwiseenterthestu󰀩ng
box in buried and sewage service applications.
NO FLAT GASKETS
The stu󰀩ng box gasket and bonnet gasket are pressure
energized rubber O-rings. This assures sealing of the valve
components without the need for excessive bolt loading as
is required by at gaskets. The O-ring seals are reusable,
which eliminates the need for time consuming cleaning,
scrapping and cutting of new gaskets.
AVAILABLE IN UL AND FM CONFIGURATIONS
The Series 2500 valve can be furnished in congurations
thatareULListedandApprovedbyFMApprovals.
