Series 45 In-Depth

Series 45 Gate Valves

The Series 45 valve is our all ductile-iron valve that meets or exceeds the requirements of AWWA C509. Series 45 MJ x MJ gate valves tested up to 350PSI up through 12″. Since they are all ductile iron, they also meet or exceed the requirements of AWWA C515. Valves are available in all end configurations including grooved ends, tapping valves, and OS&Y. Every valve is 100% tested beyond AWWA C509, including low pressure testing. All valves are certified to NSF 61 and NSF 372, meeting all requirements of the Safe Drinking Water Act.

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…

Stainless steel stem

  • 400 series Stainless Steel is AVK’s  standard stem material, providing twice the yield strength required by AWWA; Potential for bent and broken stem is eliminated
  • Threads are cold-rolled, work-hardening the steel, and ensuring smooth thread edges for low operating torque
  • Unique wiper-ring protects stem from contact with soil and water

EPDM wedge w/ captive wedge nut

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

Anode lug

  • Unique tapped lug and set screw provide a metal-to-metal termination point for cathodic corrosion protection
  • Can accommodate up to 2 – #10 AWG and may also be used as connection for tracer wire

 

Anti-rotation T-bolt lugs

  • T-bolt lugs keep T-bolt heads in position for secure installation of all bolted MJ connections

Features

One Piece Main Valve

  • This virtually indestructible valve is made from a ductile iron core, completely encapsulated in EPDM
  • One piece valve is corrosion-proof, maintenance free, and backed by a 25 year warrantee
  • Multi-part, main valves used by competitors require significant maintenance and storage of components 

Unique AVK gasket

  • Unique gasket contains a Stainless Steel insert that ensures the gasket seats easily and uniformly, reducing the chance of a pinched gasket
  • A gasket is used in three places on the AVK hydrant, further reducing the need for spare parts

Stainless upper stem

  • Standard 304 stainless upper stem vs. steel with copper sleeve, standard in other hydrants
  • Prevents corrosion or freezing of water and splitting of the sleeve
  • Options include stainless steel lower stems and 316 SS 

Serial number

  • Every AVK fire hydrant has a unique serial number engraved on the operating nut – also shown on the hydrant label
  • Serial number provides complete traceability including the date the hydrant 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

Anode lug

  • Unique tapped lug and set screw provide a metal-to-metal termination point for cathodic corrosion protection
  • Can accommodate up to 2 – #10 AWG
  • May also be used as connection for tracer wire

Monitor Elbow

  •  3″ and 4″ flanges available

Retrofitable/interchangeable parts

  • All parts are common to Series 27 Nostalgic and the Modern styles
  • Any design changes result in parts that are fully compatible with any version of AVK hydrant sold, since their introduction
  • Parts Guarantee: AVK will ship any spare part within 24 hours
  • Competitors have multiple models over many years, creating the need to store yet more repair parts
