GAS VALVES BF 32 BF32 butterfly valves are interception devices for average/low pressure gas pipelines. They may be used also for intercepting liquids when a hermetic seal, low pressure losses and compact construction in the flow direction are required. The special features of these valves are as follows: • Hermetic internal seal with shut valve • Low pressure losses • Can rotate butterfly through 360° so the seat is self-cleaning without removing the body from the pipe • Not fitted permanently to pipe, as both flow directions are possible • Butterfly with sealing ring • Chromium-plated body spherical seat for longer life with hermetic internal seal and low control torques • Highly reliable • Built to UNI 9245 standard • Face to face according to UNI 9245 and ISO 5752, MSS - SP 67, BS 5155-74 standard Functional features:* ¢ Maximum working pressure: 16 bar (UNI PN16) - 19 bar (ANSI 150 RF) ¢ Working temperature: -10 ÷ +150°C ¢ Fluids: Gas, compressed air, hydrocarbons Design features: ¢ Nominal dimensions DN: DN 50 ÷ 250 ¢ Flanged connections: UNI PN16; class ANSI 150 RF Materials: ** ¢ Body: ASTM A 105 ¢ Butterfly: ASTM A105 ¢ Stem: AISI 410 ¢ Fixing screws for sealing ring: AISI 304 ¢ Sleeve: Self-Lubricating Sleeve ¢ Reinforced sealing ring: VITON NBR (Only on request)
