Sant Valves is a very well-known and established brand in India for a wide range of industrial and plumbing valves. Their butterfly valves are particularly popular due to their robust construction, reliability, and suitability for various applications. Here's a breakdown of Sant butterfly valves: Key Features and Design: Wafer Type and Lug Type: Sant offers both wafer-type and lug-type butterfly valves. Wafer Type: These are designed to fit between two pipe flanges and are held in place by bolts that extend through the entire flange assembly. They are compact and lightweight. Lug Type: These have threaded lugs on the body, allowing them to be bolted directly to the pipe flanges, offering more flexibility for dead-end service (where one side of the pipe might be removed for maintenance). Body Materials: Commonly made from: Cast Iron (CI): Such as IS 210 Gr FG 200, which is strong and economical for general-purpose applications. Ductile Iron (SG Iron): Offers higher strength and durability than cast iron, suitable for more demanding industrial environments. Stainless Steel (SS): For applications requiring corrosion resistance. Carbon Steel (CS): For specific industrial needs. Disc Materials: Often available with: S.G. Iron (Ductile Iron): A common choice. Stainless Steel (SS): Such as AISI-410 or CF8 (SS304), for better corrosion resistance. Seat/Liner Materials: Nitrile Rubber (NBR): Good for water and general-purpose applications. EPDM Rubber: Excellent for hot water, steam, and some chemical applications. The seat is typically an integrally molded or replaceable rubber lining. Stem: Usually made of AISI-410 Stainless Steel for durability and corrosion resistance. Operation: Lever Operated: For smaller sizes and manual on/off control. Gear Operated: For larger sizes, providing easier operation and finer control.
