Butterfly Valves800 Series, 860 Series, 890 Series
800 Series Butterfly Valves
The 800 series valve body is manufactured from Durcor®-62™, PureFlex proprietary advanced fiber reinforced composite. Durcor®-62™ reinforcing fibers are long and interlocked; this interlocked reinforcement system transfers loads throughout the fiber matrix making the 800 series valve body virtually indestructible. It has tensile and compressive strengths that rival steel along with outstanding impact resistance that is unmatched in the industry. The strength of Durcor®-62™ enables the 800 series valve to maintain ANSI face to face dimensions, be direct threaded for lug design and allows it to be installed in any type of piping system without the need for special considerations. Durcor®-62™ excels in temperatures from -60°F to +250°F and has only .001” of thermal expansions across its full temperature range.
860 Series Butterfly Valves
PureFlex 860 series valve take resilient seated butterfly valve technology to the nest generation in reliability. The valve is bubble tight at full rated pressure of 150psi, has triple stem seals for unmatched leak free dependability and it can operate at temperatures between -60°F to +250°F (consult factory for higher temperature applications). The 860 fiber reinforced vinyl ester valve body has a zero corrosion rate, the strength of steel with only ½ the weight, and is virtually indestructible. The 860 series is used for shut-off, throttling and transfer of many corrosive and erosive fluids and has the purity required for ultra-pure and food applications.
890 Series Butterfly Valves
PureFlex Series 890 Butterfly Valve bodies are manufactured from Derakane 411/470 vinyl ester reinforced with ECR glass fiber in a proprietary process developed by PureFlex providing outstanding corrosion resistance to thousands of media. The Lug and Full-Face 890 valves offer full flange support in FRP and light gauge metal piping systems.
Ball Valves400 Series, 405 Series, 450 Series, 455 Series, 459 Series
400 Series Ball Valves
The 400 series valve is manufactured from advanced premium Derakane® 470 vinyl ester resin reinforced with glass fibers. It is highly corrosion resistant and is suitable for many chemicals from -50°F to +215°F up to 275 psi. Size range 1” – 10”.
405 Series Ball Valves
The 405 series valve is manufactured from advanced premium Derakane® 470 vinyl ester resin reinforced with carbon graphite fibers. It is highly corrosion resistant and is suitable for many chemicals from -50°F to +250°F up to 275 psi. size range 1” – 10”. Valve is static dissipative, having less than 10³ ohms-cm surface resistivity.
450 Series Ball Valves
The 450 series valve is manufactured from advanced E-Plus™ epoxy resin reinforced with glass fibers. It has outstanding corrosion resistance to solvents and is suitable for many chemicals from (-)50°F to 250°F up to 275 psi. Size range 1” – 10”.
455 Series Ball Valves
The 455 series valve is manufactured from advanced E-Plus™ epoxy resin reinforced with carbon graphite fibers. It has outstanding corrosion resistance to solvents and is suitable for many chemicals from (-)50°F to 275°F up to 275 psi. Size range 1” – 10”. Valve is static dissipative, having less than 10³ ohms-cm surface resistivity.
459 Series Ball Valves
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, cavitations, 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 with the valve in service. The 459 series valves are ½ the weight of competitors ceramic valves, offer maximum corrosion resistance, the elimination of product entrapment and provide the ultimate in flexibility and value.
Ball Check Valves100 Series
Ball Check Valves
One piece massive valve body is light weight, rugged and is corrosion resistant on the outside as it is on the inside to resist environmental attack. Available in fiberglass or carbon graphite reinforced vinyl ester or E-Plus™ epoxy materials. The valve body meets ANSI B16.10 and flange connections are compliant to ASME B16.5 Class 150. Other flange drilling options are available.
