Series 66 HDPE In-Depth

Resilient seated gate valve with HDPE ends, for drinking water and neutral liquids to max. 160°F

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
  • 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
  • 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
  • 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
