AWWA C 504 Type - Butterfly Valves3” 24” AWWA Butterfly Valve Design SpecificationsShaft SealSelf-sealing Y-type or V-type rings provide excellent sealing, low abrasionand long service life when fluid pressure increasesSelf-Lubricating BearingStainless steel backed PTFE bearing is designed for superior lubrication withlow maintenance.Corrosion Resistant ShaftShafts are ASTM A276 304 or 316 stainless steel. High strength stainless steelshaft is used for 250 psi pressure conforming to AWWA C504 standard.Streamlined DiscDisc is available in either ductile iron with stainless steel sealing edge or allstainless steel. The spherical design permit efficient sealing.BodyBody is available in cast iron or cast steel. Flange dimensions conform toASME B16.1 cIass 125 or class 250Corrosion Resistant ShaftShaft is made of ASTM A 276 304 or High strength stainless steel. Upperand Lower pieces of shafts fully comply with the design requirementsof AWWA C504 Class 150B.Shaft SealingSelf-Sealing Y-type or V-type rings can provide excellent sealing, lowabrasion, long service life when fluid pressure increases.Shaft ConnectionDisc-shaft connection is achieved by use of stainless steel pins andself-locking nuts or pin free design, that transmits the required torqueand insures strong connection between disc and shaft performing inall conditions without loosening the disc-shaft connection.DiscThe dome-shaped disc reduces the resistance to the fluid and enhancesits strength to be more reliable in service.SeatNSF approved EPDM Rubber is used for seat material for applicationsrequiring contact with Potable (drinking) water. The seat is designedto allow field removal/replacement.BodyBody is made of ASTM A536 cast iron or cast steel flange dimensionsconform to ASME B16.1 Class I25 or Class 250.SPECIAL FEATURES21

The need for standardization of butterfly valves was recognized by the American Water Works Association (AWWA) with the adoption of AWWA C504 for Rubber-Seated Butterfly Valves in 1954. This companion standard was developed by the AWWA Standards Committee on Feb. 12, 2006, to meet the need for large-diameter valves in the waterworks industry.
