AWWA BUTTERFLY VALVESDesign Details: Models 511A and 510A — 20" and SmallerSELF ADJUSTING PERMANENT PACKINGChevron type packing increases sealing force as line pressureincreases. The self adjusting packing bears on turned, groundand polished stainless steel, minimizing wear and assuring longlife. Packing is accessible for replacement without dismantlingthe valve per AWWA Standard C504.LIFETIME BEARINGSChemically inert nylon bearings are sized to meet or exceedAWWA specification pressure loads. They are self-lubricating,require no periodic maintenance and are designed to outlastthe life of the pipe line.CORROSION RESISTANT SHAFTSShafts in rubber seated butterfly valves, 3" through 20", areconstructed of centerless, ground ASTM A276 type 304 ortype 316 stainless steel bar and thus are not susceptible tocorrosion as are carbon steel or other similar materials. Shaftsare one-piece, through-shaft construction, sized to meet orexceed the requirements of AWWA Standard C504 for Class150B butterfly valves.STREAMLINED DISCSThe lens-shaped discs are designed to minimize pressure dropand turbulence. In the full open position, the disc creates nomore friction loss than a 45 elbow. Discs are secured to shaftsby stainless steel pins to transmit required torques and withstand stresses imposed under a variety of operating conditions.BODY SEATOur standard seats are constructed of Buna N rubber andbonded to the valve body. This molding process ensures thatthe disc-to-seat interference will not cause excessive wear orabrasion under normal operating conditions. The seat-in-bodydesign minimizes the effects of corrosive build up on the insideof the valve because deposits are swept away by the hardsealing edge of the disc each time the valve is exercised.HEAVY DUTY BODIESBoth Models 511A and 510A bodies are heavy duty cast iron.Model 511A flanges are fully faced and drilled in accordancewith ANSI B16.1, Class 125 standard for cast iron flanges.Model 510A mechanical joint end connections are in accordancewith AWWA C111 and ANSI 21.11. The actuator mountingtrunnion is machined and drilled for a 4-bolt connection.3

AWWA BUTTERFLY VALVESFeatures and Benefits of Milliken Models 511A and 510A — 20" and SmallerFEATUREBENEFIT Seat-in-body design Seat molded in recessed body cavity, protected bymetal on 3 sides Valve withstood proof-of-design testing of 100,000cycles - AWWA only requires 10,000 cycle proof-ofdesign testingReduces seat failure due to corrosive buildup inthe valve and pipeline. No hard ware to loosen. Noperiodic maintenance required. Rubber protectedfrom flow media to increase seat life. Proven reliability over the life of the valve Provides a tight disc-to-shaft pin connection, greatlyreducing the possibility of loosening through vibration Higher Cv: lower head loss results in energy savings forcustomer’s system Prevents galvanic corrosion and provides lowercoefficient of friction Self-adjusting, lasts the life of the valve Through-disc pinning Symmetrical lens-shaped disc Nonmetallic bearings Chevron V-type packingTYPE OF MATERIALVALVE SIZECVVALVE SIZECV3"32310 "44584"57512"64206"129414"873820 "8"2300VALVE SIZECVVALVE SIZEBODY16"114133 " - 4"Ductile IronCF-8MType 304SS18 "144446"Cast IronCF-8MType 304SS178328 " - 20 "Cast IronCast Iron /316SS EdgeType 304SSC V values for the 511A and 510A in thefull open positionDISCSHAFTOther materials available upon request4

AWWA BUTTERFLY VALVESSuggested Specification for the Milliken Rubber Seated Butterfly Valve, Sizes 3" through 20"GENERALPAINTINGButterfly valves shall be manufactured in accordance with the latestrevision of AWWA C504, Class 150B and conform to NSF Standard 61.The manufacturer shall have produced AWWA butterfly valves for aminimum of five years. All valves shall be either 511A Flanged or 510AMechanical Joint and comply with the following details.All surfaces of the valve interior shall be clean, dry and free fromgrease before painting. The valve interior and exterior, exceptfor disc edge, rubber seat and finished portions shall be evenlycoated with a 2-part liquid epoxy to comply with NSF61 and AWWAStandard C504.VALVE BODIESTESTINGValve bodies shall be constructed of ASTM A126, Class B cast iron.Flanged valves shall be fully faced and drilled in accordance withANSI Standard B16.1, Class 125. Mechanical joint end connectionsare in accordance with AWWA C111 and ANSI 21.11.PROOF OF DESIGNVALVE SEATSRubber body seats shall be of one piece construction,simultaneously molded and bonded into a recessed cavity in thevalve body. Seats may not be located on the disc or be retained bysegments and/or screws.VALVE BEARINGSValve bearings shall be of a self-lubricating, non-metallic materialto effectively isolate the disc-shaft assembly from the valve body.Metal-to-metal thrust bearings in the flow stream are not allowed.VALVE DISCThe disc shall be a lens-shaped design to afford minimal pressuredrop and line turbulence. Materials of construction shall be: 3" - 6" — ASTM A351 Gr. CF8M stainless steel disc 8" - 20" — ASTM A126, Class B cast iron disc with a stainlesssteel type 316 edgeDiscs shall be retained by stainless steel pins which extendsthrough the full diameter of the shaft to withstand the specifiedline pressure up to valve rating and the torque required to operatethe valve. Disc stops located in the flow stream are not allowed.VALVE DISCValve shafts shall be of stainless steel type 304. At the operatorend of the valve shaft, a packing gland utilizing “V” type chevronpacking shall be utilized.5Hydrostatic and seat leakage tests shall be conducted in strictaccordance with AWWA Standard C504.The manufacturer furnishing valves under the specification shall beprepared to provide Proof of Design Test reports to illustrate that thevalves supplied meet the design requirements of AWWA C504.MANUAL ACTUATORSManual actuators shall be of the traveling nut, self-locking type andshall be designed to hold the valve in any intermediate positionbetween fully open and fully closed without creeping or fluttering.Actuators shall be equipped with mechanical stop-limiting devicesto prevent overtravel of the disc in the open and closed positions.Actuators shall be fully enclosed and designed to produce thespecified torque with a maximum pull of 80 lb. on the handwheelor chain wheel. Actuator components shall with stand an inputtorque of 450 lb. ft. at extreme operator position without damage.Manual actuators shall conform to AWWA C504 and shall beMilliken MDT or an approved equal.
