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.

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.
