Series 65 with HYMAX GRIP® technology

There are many situations that require valves and hydrants with additional restraining power. AVK valves and hydrants equipped with the patented technology of the HYMAX GRIP®. Designed using HYMAX’s innovation and patented technology, our flow control solutions work with ductile iron, PVC and HDPE pipes and are suitable for a wide variety of applications.

The Series 65 valve is our all ductile-iron valve that meets or exceeds the requirements of AWWA C515. Every valve is 100% tested beyond AWWA C515, 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
