Series 18:  Combi-Tee

The American AVK Series 18 is another AVK innovation designed to save time on the installation of hydrant laterals. It reduces the number of joints - which reduces leakage. It is competitively priced to replace the cost of the fitting and valve.

Features:

  • Certified to NSF 61 by Underwriters Laboratories
  • Sizes: 6" x 6", 8" x 6", 12" x 6"
  • Push-on or MJ connections available
  • Mainline laying length to AWWA C153
  • All AVK Series 18 combi-tees meet or exceed the requirements of AWWA C509 and C153 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
