This thermoplastic butterfly valve improves performance
The new 565 butterfly valve (photo) valve is said to be strong yet lightweight. It consists of high-performance plastic components that include polyvinylidene fluoride (PVDF) disc with fiber-reinforced polyamide housing and ethylene propylene diene monomer (EPDM) rubber or FKM (Viton) seals, making it ideally suitable for pressures up to 16 bars and temperatures ranging from –10 to 80°C. Available in sizes from NPS 2 through 12 (DN50-300), the 565 valve is 60% lighter than a comparable metal valve, allowing a single technician to safely and easily handle it during installation. The valve offers high corrosion resistance, long service life and more effective use of energy and resources during industrial production, says the company. — Georg Fischer LLC, Irvine, Calif.
