Difference between Clamped Butterfly Valve and Flanged Butterfly Valve
This paper systematically analyzes the core differences between butt-clamp butterfly valve and flange butterfly valve. Clamped butterfly valves have a simple structure and are installed by clamping between pipe flanges, which makes them easy to disassemble and install, and are suitable for occasions where space is limited or frequent maintenance is required (e.g., ventilation and water treatment systems); flanged butterfly valves use prefabricated flanges for butt joints, which provide a solid connection and better sealing performance, especially high pressure resistance, and are suitable for petrochemical, electric power and other highly demanding fields. Both of them have their own emphasis on sealing, maintenance cost and application scenarios, which provide a key reference for industrial fluid control selection.
