CONSTRUCTION

BOLTLESS RESTRAINTProvides positive joint restraint with increased deflection. No nuts and bolts to corrode. Lowers installation costs.

DUCTILE IRON OPERATING NUTProvides strength

and durability.

LIFTING DEVICES 14"- 66"Valve is constructed of

high-strength ductile iron with integral lifting devices. This allows the

valve to be handled without having to lift the

valve by the operating nut, which could cause

damage to the valve stem.

BEVEL GEAR - SPUR GEARFor horizontal installation in buried service use Bevel Gear. Use Spur Gear for vertical installation.

STAINLESS STEELNUTS AND BOLTS Helps provide additional corrosion resistance.

EPOXY COATINGINSIDE AND OUTHelps ensure corrosion resistance for longer service life.

DUCTILE IRONCONSTRUCTIONGreater strength, durability, and lighter weight than gray iron construction. 250 psig rating.

DUCTILE IRON WEDGE IS FULLY ENCAPSULATED

WITH EPDM RUBBERHelps ensure zero leakage

with low stem torques.

SMOOTH OVERSIZEDWATERWAY

Helps reduce pumping costs CAST FLATSAllow the valve to stand upright during storage or installation.

16”-60” SERIES 2500 RESILIENT WEDGE GATE VALVE WITH FLEX-RING® ENDS

The 16”–60” Series 2500 Resilient Wedge Gate Valves with Flex-Ring Ends have these standard benefits:• Positive joint restraint instead of friction-based restraint. • Significant labor savings with less installation time. • Twice the deflection of friction-style restrained joints. • No bolts or nuts to inventory or keep track of on jobsite. • No point loads or digging into the connecting pipe wall.

• Flex-Ring offers a more even distribution of thrust loads. • Restraining components protected by bell socket. • Ideal for installation near structures where differential settlement may occur. • No restraining hardware to corrode.

Valves 16 in.–60 in. shall be resilient wedge type rated for 250 psig cold water working pressure and employ the use of a boltless positive joint restraint equal to the Flex-Ring joint. Friction style restrainers, which point load the adjoining pipe, will not be allowed. All cast ferrous components shall be ductile iron, ASTM A536. Valves 16 in.–60 in. shall meet or exceed all applicable requirements of ANSI/AWWA C515. The words "Ductile Iron" or "D.I." shall be cast on the valve. The wedge shall be constructed of ductile iron fully encapsulated with EPDM rubber.

The wedge shall be symmetrical and seal equally well with flow in either direction. Wedge guides shall be equipped with male guide covers. The use of auxilliary bronze rollers and plow-style shoes are not acceptable. The wedge nut shall be independent of the wedge and held in place on three sides by the wedge to prevent possible misalignment. Valves 16 in. and larger shall be furnished with spur gears for vertical

installations and bevel gears for horizontal installations. Valves shall be Certified to NSF/ANSI 61and NSF/ANSI 372.

Body bolting material shall be 304 stainless steel unless otherwise specified. Bolts may have either regular square or hexagonal shaped heads with dimensions conforming to ANSI B18.2.1. Metric size and/or socket head cap screws, or bolts, are not allowed. The operating nut shall be constructed of ductile iron. All gaskets shall be pressure energized O-ring type seals. Stem shall be sealed by three O-rings. O-rings set in a cartridge shall not be allowed. The valve shall have thrust washers located with 1 above and 1 below the thrust collar to assist operation of the valve. All internal and external surfaces of the valve body and bonnet shall have an epoxy coating, complying with ANSI/AWWA C550. Valves shall be AMERICAN Flow Control’s Series 2500 Resilient Wedge Gate Valve.

FEATURES

BENEFITS

SPECIFICATIONS

DUCTILE IRON CONSTRUCTIONThe 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 are provided in a compact, lighter design.

TRIPLE O-RING STEM SEALS

Sealing the lubrication chamber is a series of three O-ring stem seals. The O-rings help isolate the lubrication chamber.

EPOXY COATINGThe 16 in.–60 in. Series 2500 valves are epoxy coated both on the interior as well as the exterior of the valve. The 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 flange surfaces are fully epoxy coated.

LIFTING DEVICES 16"–60"Stuffing box is constructed of high-strength ductile iron with integral lifting device. This allows the valve to be handled without having to lift the valve by the operating nut. 42 in. - 60 in. valves have integrally cast lifting lugs.

THRUST WASHERSThrust washers are located above and below the stem collar to reduce operating input torque and assist in trouble-free operation of the valve.

NO FLAT GASKETSThe stuffing box gasket and throat flange gasket are pressure-energized rubber O-rings. This provides a seal without the need for excessive bolt loading as is required of flat gaskets.

FEATURES/BENEFITS/SPECIFICATIONS

AMERICAN Flow Control’s 14 in.–66 in. Series 2500 Ductile Iron Resilient Wedge Gate Valves are suitable for use in potable water, sewage and fire protection systems. These valves have a rated working pressure of 250 psig with zero leakage. The waterway is clear and unobstructed.

ADVANTAGES OVER BUTTERFLY VALVES• No disc in waterway to restrict flow or to increase pumping costs.• Allows passage of pigging devices.• Internal parts can be serviced without cutting valve out of pipeline.• 250 psig rating provides for future pressure increases over the150 psig pressure rating found on most butterfly valves.

ADVANTAGES OVER DOUBLE DISC GATE VALVES• Zero allowable leakage.• Lower torque requirements to operate valve.• 250 psig pressure rating compared to the 150 psig rating found on double disc gate valves.• Epoxy coated inside and out.• Lighter total valve weight.• Single gate construction. Double disc gate valves have multiple parts that can seize together.• Bypasses and rollers, tracks and scrapers are not needed.
