Butterfly Valves
SBP Butterfly Valves, Fluoropolymer-Lined
Fluoropolymer-Lined SBP Butterfly Valves are proven high quality process valves for a wide range of applications. They are used in such diverse industries as chemical, petrochemical, pharmaceutical, pulp and paper, mining, and associated fields. They are suitable for installation in piping systems in accordance with DIN PN10/16 or ANSI 150lbs, fitting flanges per EN 1092 or ASME B16.5. Face-to-face dimensions are in accordance with EN 558-1 row 20, as well as ASME B16.10.
SBP bodies are available in wafer-style, with integrated centering lugs, or in lug-style with threaded bolt holes. Depending on the application the 2-part bodies can be made from epoxy-coated ASTM A216 WCB cast steel (1.0619), from CF-8M (AISI 316SS) Stainless Steel (1.4408), or from AISI 316L (1.4404). Integrated ISO 5211 mounting flanges allow direct mounting of 90° actuators. A key feature of SBP Butterfly Valves is the slim profile, bubble-tight 1-piece disc/stem assembly which maximizes flow capacity and offers polished sealing surfaces for leak-proof performance. Disc cores are made from ASTM A240 Duplex SS (1.4462), and the thoroughly anchored encapsulation guarantees the required bonding strength for vacuum applications.
Customers benefit greatly from the extended life span and hysteresis-free characteristics of Swissfluid Butterfly Valves during control applications. Liners with wide sealing grooves eliminate the need for additional gasketing by the end-user. Replacement of our liners is easily accomplished in the field.
Body liners made from highly stable materials such as PTFE, PTFE-AS (anti-static), PTFE-T (for vacuum service), UHMWPE or PVDF are readily available. Discs can be encapsulated with PFA, PFA-AS (anti-static), ETFE or Polypropylene. Discs can also be furnished in solid one-piece construction from 1.4462 Duplex SS, welded 316L SS, grade 2 Titanium, Hastelloy C, or special alloys. The notched stem with the rated breaking point outside the valve is an important additional safety feature for environmental protection.
Of course proper safety factors always have to be considered for pneumatic or electric actuator applications.
EN 12266-1 and API 598 – required tightness is met across the entire pressure and temperature range from -40°C (-40°F) to 230°C (446°F) resp. 1mbar (0.01psi) to 16 bar (232psi) with features such as high-strength body halves connections, maintenance-free shaft sealing per TA-Luft (VDI 2440) and elastomeric backing of the liner.
Highly corrosive, abrasive and even toxic liquids, vapors or poisonous gases constantly challenge the quality, functionality and safety of specified butterfly valves.
Swissfluid's lined SBP Butterfly Valves meet and exceed all criteria in the harshest environments!
SBE Butterfly Valves, Elastomer-Lined
SBE Butterfly Valves are well established elastomer-sealing process valves used in a wide range of applications in such diverse industries as chemical, petrochemical, pharmaceutical, pulp and paper, mining, and associated fields. The combination of EPDM (liner) and encapsulated disc (PFA) is perfectly suited for low-concentration acids and lyes containing solids. They are suitable for installation in piping systems in accordance with DIN PN10/16 or ANSI 150lbs, fitting flanges per EN 1092 or ASME B16.5. Face-to-face dimensions are in accordance with EN 558-1 row 20, as well as ASME B16.10.
SBE bodies are available in wafer-style, with integrated centering lugs, or in lug-style with threaded bolt holes. Depending on the application the 2-part bodies can be made from epoxy-coated ASTM A216 WCB cast steel (1.0619), from CF-8M (AISI 316SS) Stainless Steel (1.4408). Integrated ISO 5211 mounting flanges allow direct mounting of 90° actuators. A key feature of SBE Butterfly Valves is the slim profile, bubble-tight 1-piece disc-stem assembly, which maximizes flow capacity and offers polished sealing surfaces for leak-proof performance.

Customers benefit greatly from the extended life span and hysteresis-free characteristics of Swissfluid Butterfly Valves during control applications. Liners with wide sealing grooves eliminate the need for additional gasketing by the end-user. Replacement of our liners is easily accomplished in the field.
Body liners made from highly stable materials such as EPDM, white EPDM, NBR, FPM (Viton), VMQ (Silicone), or SBR are readily available. The disc can be encapsulated with PFA, PFA-AS (anti-static), PVDF or ETFE. Discs can also be furnished in solid one-piece construction from 1.4462 Duplex SS, welded 316L SS, grade 2 Titanium, Hastelloy C or special alloys. The notched stem with the rated breaking point outside the valve is an important additional safety feature for environmental protection.
Proper safety factors always have to be considered for pneumatic or electric actuator applications.
Features such as high-strength body halves connections, O-ring shaped sealing lip and the dynamic maintenance-free shaft sealing grant an excellent performance along the entire life span.
EN 12266-1 and API 598 – required tightness is met across the entire pressure and temperature range of 1 mbar to 16 bar (0.01psia – 232psi). -40°C to 230°C (-40°F to +446°F) depending on nominal size as well as choice of liner material and disc encapsulation.
Highly corrosive or abrasive and even toxic liquids, vapors or poisonous gases constantly challenge the quality, functionality and safety of specified butterfly valves.
