These double block-and-bleed valves are certified for fire safety
Armaturenfabrik Franz Schneider
The Taurus Series of double block-and-bleed valves (photo) provide a double-isolation function with a twin-ball design. The valves are available from 1 to 6 in. full-bore (8-in. reduced-bore). The ball valves have an anti-blowout stem and an anti-static design, and are fire-safety tested and certified according to API 607 and ISO 10497. Where necessary, polyether ether ketone (PEEK) is available as a seat material and Duplex as a ball material. Stems are generally made of XM-19, an austenitic stainless-steel grade that has a greater corrosion resistance and higher yield strength than 316 stainless steel. All other trim materials and all non-wetted parts are provided in 316 stainless steel, making the valves suitable for installation in corrosive environments.
