459 Series Overview

Tough Valve For Tough Services!

  • Corrosion Resistant
  • Strong as Steel
  • 1/2 the weight of Steel

The PureFlex 459 Series ceramic-lined composite ball valve is a superior quality, ANSI Class 150 valve engineered with features not yet available in any other ceramic valve. The valve body is manufactured from strong, light weight advanced premium E-Plus™ epoxy resin reinforced with carbon graphite. The ceramic liner / seats and ball are partially stabilized zirconia (PSZ) which provides unmatched impact resistance. The valve is 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. The 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 in service. The 459 series valves are 1/2 the weight of competitors ceramic valves, offer maximum corrosion resistance, and the elimination of product entrapment, and provide the ultimate in flexibility and value.
