Series 66: Gate Valves with HDPE Fusible Ends

The American AVK Series 66 is designed especially for use in polyethylene water distribution systems. The valve is identical to our premier resilient wedge gate valve with one exception: The PE-pipe stubs are already mounted. This means lower installation costs and leak proof joints.

Features:

  • NEW: 2-inch and 3-inch sizes now available
  • Sizes 4-inch through 12-inch available
  • Hydrant bases available with PE connectors
  • The patented valve to pipe joint is water-tight and high strength - stronger than the pipe itself
  • Optimum corrosion protection and finish of the valve joint is ensured by the heat activated polyolefin covering meeting the requirements of AWWA C216
  • Connection to all types of PE possible
  • PE pipe stubs comply with AWWA C906 and are NSF 61 certified.
  • The valve can be installed using socket fusion or butt welding processes - a boltless assembly means corrosion free joints
  • The valve joint can resist thrust loads - eliminating the need for thrust blocking
  • All AVK gate valves with PE ends meet or exceed the requirements of AWWA C515 where applicable
  • 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
