PureFlex – 800 Series Butterfly Valve

General Details

The PureFlex 800 Series fully lined composite valve is manufactured to be corrosion resistant inside and out in hostile services. The valve has the strength of steel with ½ the weight and is 10× more impact resistant than standard FRP. They are used for shut-off and throttling of most known corrosive fluids, and have the purity required for ultra-pure applications. The 800 Series can be used for end of the line service and is bubble tight at full rated pressure of 150psi, has triple stem seals and can operate at temperatures of -60ºF to +250ºF.

The 800 Series valve body is manufactured from Durcor®, PureFlex’s proprietary advanced fiber reinforced composite. Durcor® 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® 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® excels in temperatures from -60°F to +250°F and has only .001” of thermal expansions across its full temperature range.

PureFlex 860 Series valves take resilient seated butterfly valve technology to the next 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 the transfer of many corrosive and erosive fluids, and has the purity required for ultra-pure and food applications.
