BF 31 Butterfly Valve
Size Range: DN 300–600 | 12"–24"The Pietro Fiorentini BF 32 is a butterfly valve designed for medium and low pressure gas distribution, compressed air and hydrocarbon service. It covers DN 50 to 250 (2 to 10 inches), with UNI PN16 flanged connections rated to 16 bar or ANSI 150 RF connections rated to 19 bar, and a working temperature range of -10°C to +150°C.
A butterfly valve isolates flow with a disc that rotates a quarter turn on a central stem. On the BF 32 the disc seals against a chromium-plated spherical seat using dual sealing rings, and an in-line seal check port allows the integrity of the seal to be tested. The disc can rotate through 360 degrees, which gives a self-cleaning action across the seat. The body is ASTM A 105 steel with an AISI 410 stem; Viton seals are standard and NBR is available on request.
The valve is built to UNI 11354, ISO 5752 and MSS-SP 67. When choosing between PN16 and ANSI 150 versions, match the flange standard of the existing pipework and check that the line pressure sits within the rating for that connection. Seal material should be chosen for the gas composition and temperature, and the operator for the size and how often the valve is cycled.
