Short body flanged butterfly valves are the new “state of the art” butterfly valves available on the market, with a very compact design and various materials of constructions, they can be applied in several plants. Compatible with BS, DIN and ANSI flanges, the short body flanged butterfly valves have the rubber liner vulcanized on the body of the valve, allowing strong and reliable tightness, as well as the O ring cast on the body, that prevents any need of gaskets. Short body flanged butterfly valves are manufactured as centric type disc, they can stand both directions of fluid and are maintenance-free. The body, not in contact with the fluid, can be lined with EPDM, BUNA, PTFE, Neoprene or Viton: in this way we can apply these butterfly valves to any plant and for every medium, simply mounting the suitable disc in ductile iron, stainless steel 304 or 316, Al-Bronze C95400. Such valves can be installed in any position. Short body flanged butterfly valves come reducing gear and handwheel (standard execution), pneumatic operator with single or double effect, electric actuator on request.
