BF 31 Butterfly Valve for Low Pressure Loss Interception
The BF 31 is an interception device designed to guarantee low pressure losses in medium and low-pressure gas distribution networks. Suitable for use with natural gas and previously filtered non-corrosive gases, it can also be used for intercepting liquids where hermetic sealing, low pressure losses, and compact construction are required. The valve features a chromium-plated body spherical seat for high reliability and long life.
Supplied and supported across Saudi Arabia, the GCC and the Middle East from Al Khobar

Frequently asked questions
What is the BF 31 butterfly valve used for?
The BF 31 is an interception valve with low pressure losses for natural gas and previously filtered non-corrosive gases, mainly in medium and low pressure distribution networks and district stations. It can also shut off liquids where a hermetic seal and compact construction are needed. The butterfly can rotate 360 degrees, cleaning the seat without removing the body from the pipe.
What sizes and pressures does the BF 31 cover?
The BF 31 brochure lists DN 300 to DN 600 (12 to 24 inch), with a maximum working pressure of 16 bar on PN 16 flanges or 19 bar on ANSI 150 RF flanges. Seal material can be Viton or nitrile. For smaller lines from 2 to 10 inch, choose the BF 32.
Is the BF 31 available for projects in the GCC?
Yes. Pietro Fiorentini Saudi Industry in Al Khobar supplies and supports the BF 31 for gas distribution projects in Saudi Arabia, the UAE, Qatar, Kuwait, Bahrain and Oman. Tell us the DN, flange standard, fluid and operating pressure for a quotation.
