Product Features & Benefits

  • SUPERIOR QUALITY: ANSI Class 150 ceramic lined ball valves manufactured from strong, light weight advanced premium E-Plus™ epoxy resin reinforced with carbon graphite
  • UNMATCHED IMPACT RESISTANCE: The ceramic liner / seats and ball are partially stabilized zirconia (PSZ) which provides unmatched impact resistance
  • MEETS DEMANDING SERVICE REQUIREMENTS: Able to withstand abrasion, cavitation, wear, thermal cycling, and severe corrosive media and environments up to 275°F. The 459 Series ball valve exceeds Class IV shut-off and its stem seal will meet your routine or most rigid service requirements
  • ONE-PIECE BODY: Massive one-piece body meets ANSI B16.10 dimensions and its ISO 5211 universal mounting pad and flange mounting makes automation simple even with the valve in service
  • ZERO CORROSION: Offers maximum corrosion resistance and the elimination of product entrapment
  • ½ THE WEIGHT OF STEEL: The 459 series ball valves are ½ the weight of steel valves and provide the ultimate in flexibility and value
