Home > Stainless Steel Butterfly Valves
Weston Stainless is based in Midland, UK, and specializes in being the leading producer and distributor of superior stainless steel valve solutions that stand for quality, precision, and reliability across most industries. Our Stainless Steel Flanged Butterfly Valves are developed from superior grade materials. Characterized by high corrosion resistance and durability. With a disc-shaped closure element and flanged end connections these valves provide safe installation and effective flow control. Suitable for chemical, water treatment and industrial applications, they offer reliable performance in high-flow and pressure situations.
Stainless Steel Flanged Butterfly Valves are produced with high-grade materials consisting of Chromium (18–20%), Nickel (8–14%) and Molybdenum (2–3%) in 316 models for improved corrosion resistance. They show good mechanical properties such as tensile strength of 515–620 MPa, yield strength of 205–290 MPa, and satisfactory elongation (30–40%). Physically, these valves possess a density of 7.9 g/cm³, a melting point of approximately 1400°C, and good thermal conductivity, which makes them suitable for high-temperature applications, pressure, and corrosive or sanitary flow control purposes.
