Series 145: UL/FM Gate Valve for Fire Protection 2.5”- 8”

Series 145 is AVK’s gate valve designed specifically for indoor fire protection applications. By focusing their design effort on meeting stringent UL/ULC and FM requirements, AVK engineers have created a gate valve with lighter weight and unique features for fire protection. Series 145 Gate Valves are made of ductile iron and have a 250 PSI rated working pressure. They are available in both NRS and OS&Y configurations, with flanged, grooved, and flanged x grooved ends, in sizes 2½" - 8"


  • "Slim Wedge” design results in a stronger and lighter, easier-to-handle gate valve; fully encapsulated EPDM wedge prevents deterioration from disinfectants
  • Comes standard with 1 boss hole, drilled, tapped, and plugged to accommodate draining
  • 304 stainless steel stems are formed by cold-rolled threading process, eliminating bent or broken stems 
  • Fixed wedge-nut provides higher torque resistance and prevents rubber wear and leakage
  • Electrostatically applied, fusion bonded epoxy resin provides extended corrosion resistance 
  • Bonnet bolts are fully isolated against corrosion to eliminate bonnet bolt failures 
  • All AVK Series 145 Gate Valves are made in the USA and covered by a 2 year warranty
