The butterfly valve BF 31 is an interception device able to guarantee low pressure losses. It may be used also for intercepting liquids when a hermetic seal, low pressure losses and compact construction in the flow direction are required.

Suitable for use with natural gas and previously filtered non-corrosive gases, it is mainly used in medium and low pressure gas distribution networks.

For the Pietro Fiorentini Group, valves are produced by TIV Valves, a Group company specialized in the production of valves based in Rescaldina (MI)
