Ceramic Lined Ball Valves
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.
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
- FLOW CONTROL OPTIONS:
- Full CV
- 60 Degree
- 30 Degree
- 15 Degree
