• 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
• Stainless steel bolts
• 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
• (2) 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
• Ductile iron wrench nut, bronze wedge nut, thrust collar, Buna-N nitrile rubber bonnet gasket, wiper ring, O-ring stem seals and O-ring gland seal
• All AVK gate valves are covered by a 10-years warranty
• Made in USA
