Features:
AVK bolting and gasket system

  • 316 stainless steel bonnet bolts will never come in contact with water or soil and are 100% protected against corrosion.
  • Unique gasket has round inserts for bolts, which are countersunk into the tapped valve body and capped with hot-melt.
  • Easily disassembled after years of service - but, you’ll never need to...

Stem material 
AVK’s standard stem material can be offered in:

  • stainless steel 316 or Aluminium bronze C63020, providing more than twice the yield strength required by AWWA; Potential for bent and broken stem is

    eliminated.

  • Threads are cold-rolled, ensuring smooth thread edges for low operating torque.

  • Unique wiper-ring protects stem from contact with soil and water.

EPDM/NBR wedge w/captive wedge nut

  • Standard EPDM wedge is taste and odor free, stands up to chlorine and other disinfectants.

  • Optional NBR wedge can be supplied for harsh mediums.

  • Wedge nut is fully encapsulated in the wedge, resulting in efficient mechanical motion and 10X the open/close operations vs. competitors; Provides higher torque resistance and prevents rubber wear and leakage.

Serial number

  • Every AVK valve has a unique serial number engraved on the stem – also shown on the valve label; Serial number provides complete traceability to the date the valve was built, and every operation performed throughout the manufacturing process.
  • AVK is the only gate valve and fire hydrant manufacturer in the USA with a Quality Assurance program that requires serializing every product for traceability.
