The Sure Flow BFVL 3 Inch Butterfly Valve is a top-of-the-line solution designed for a range of applications in industrial settings, municipal systems, and HVAC installations. This butterfly valve features a durable American Society for Testing and Materials (ASTM) A-536 Ductile Iron body with 316 Stainless Steel disc material, ensuring high strength and corrosion resistance. With an ISO 9001:2008 certification, this valve is suitable for on/off isolation, throttling, and dead-end services with minimal leakage. Its extended neck design allows for easy insulation application, while the one-piece construction ensures reliability and ease of operation.
Product Specifications
Additional Information Additional Information
Bi-directional dead-end capabilityAll Butterfly Valve bodies are ductile iron 65-45-12. They are bi-directionally tested in both directions and are bubble tight with zero leakage. Lug style bodies are full rated and suitable for ASM E Class 125 and ASME Class 150 flanges. Wafer style bodies are suitable for ASME Class 125, ASME Class 150, JIS, DIN or B.S. flanges. Secondary seals are self-adjusting. All elastomers and all internal bearings are non-corrosive and non-metallic. EPDM seats are suitable for 250ºF sustained high temperature and capable of 2000 ppm on chlorinated applications.TestingAll valves are factory tested on both sides for bi-directional installations to zero leakage and bubble tight.
Benefits Benefits
Allows for 2" insulationHigh strength body when in tension (lug body)Elimination of shaft to body seizureExcellent in full vacuum distortion proof primary shaft seal, minimal seat movement and consistent displacement on closingHigh torsional capabilities with zero disc deflection

Features Features
Extended neck design for ample application of insulation.One-piece / uni-body construction of cast ductile iron designed to accommodate ASME Class 125 flanges or ASME Class 150 flanges.Integral ISO 5211 mounting flange will accept all styles of hand levers, multi-turn manual gears and power operators/actuators.Acetal Plastic "Acetal" stem bushings to assure long life even during extended periods of inactivity and to decrease operating torque which eases manual operation or power assisted operation.One-piece resilient seat with a molded-in (integral) o-ring seal eliminates the need for additional flange gaskets. The Butterfly Valve body is designed to limit seat compression to optimum dimensions.One-piece resilient phenolic back seat has molded-in (integral) o-ring seal for upper and lower valve shafts and works with disc edge hub seals to provide a double stem seal.Phenolic backed seat features:Dimensionally stable seat sealing surfaceMinimal seat wear, extending seat lifeBlow-out proof seatNon-distorting shaft hole with molded-in (integral) o-ring sealSuitable for open left or open right operation.Two-piece shaft designButterfly Valve is standard with a hard back seat. There is no movement of the seat which results in a constant torque and dead end zero leakageButterfly Valves are available in sizes up to 48 inches.
