Series 45:  Ductile Iron Gate Valves

The series 45 valve is our all ductile-iron valve that meets or exceeds all of the requirements of AWWA C509. Since they are all ductile iron, they also meet or exceed the requirements of AWWA C515 with the full wall thickness of AWWA C509. It is available in all end configurations including grooved ends, tapping Valves, and OS&Y. The grooved ends are to AWWA C606.


  • Certified to NSF 61 by Underwriters Laboratories
  • All AVK gate series 45 valves meet or exceed the requirements of AWWA C509 and C515
  • Stainless steel stem - standard
  • Lead free
  • Threads rolled in a separate cold pressing process to enhance strength
  • Rolled threads ensure smooth thread edges and low operating torques
  • Twice the yield strength required by AWWA eliminates bent and broken stems
  • Bronze stems are available
  • Stainless steel bolts - standard
  • Packing gland bolts and bonnet bolts are stainless steel for corrosion resistance
  • Bonnet bolts are countersunk and capped with hot melt to totally isolate the bolts from corrosive environments
  • O-ring bonnet gasket wraps each bolt to prevent corrosion
  • Bonnet blow offs due to bolt corrosion eliminated
  • Fully encapsulated wedge with EPDM - standard
  • Ductile iron wedge fully encapsulated in EPDM rubber with an integral bronze stem nut for optimum corrosion protection and precision wedge tracking
  • EPDM resists attack from chloramines
  • Ductile iron gland flange for protection should the valve be over-torqued in the closed direction - will not break or crack
  • Gland flange equipped with cast in lifting lugs for easy handling
  • Wiper ring - to prevent impurities from entering the stem and to protect the o-rings
  • Two o-ring stem seals to reduce friction and prevent wear and tear - replaceable under full pressure
  • Third o-ring stem seal protects upper stem from impurities entering from the water way
  • Coating to AWWA C550 - Electrostatically applied fusion bonded epoxy coating inside and outside for excellent corrosion resistance
  • 100% testing - All valves tested to 250 PSI / 500 PSI as required by AWWA
  • For UL, ULC and FM listed valves, see the Fire Protection Section Series 45
