The series 55 valve is our large diameter ductile-iron gate valve meeting or exceeding the requirements of AWWA C515. It comes in MJ x MJ and FLxFL versions. All valves come pre-fitted with an F16 mounting plate to mount gearing or motorized actuators. Bevel or spur gearing is available on request.

Features:

• All AVK gate series 55 valves meet or exceed the requirements of AWWA 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 failure 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
• Stainless steel lifting eyes supplied on every valve
• 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.
