The Difference Between Wafer-Type and Flanged Butterfly Valve

This article systematically analyzes the key differences between wafer-type butterfly valves and flanged butterfly valves. Wafer-type butterfly valves feature a lightweight and simple design; they are installed by clamping between pipe flanges, making them easy to install and remove. They are suitable for applications with limited space or those requiring frequent maintenance (such as ventilation and water treatment systems); Flange-mounted butterfly valves, on the other hand, utilize pre-fabricated flanges for a secure connection, offering superior sealing performance and exceptional high-pressure resistance, making them suitable for demanding industries such as petrochemicals and power generation. Each type has distinct strengths in terms of sealing performance, maintenance costs, and application scenarios, providing a critical reference for selecting industrial fluid control valves.

Applications of Wafer-Type Butterfly Valve

Thanks to their compact design, ease of operation, and excellent sealing performance, wafer-type butterfly valves are widely used in piping systems across industries such as oil and gas, chemicals, water treatment, thermal power plants, and sulfuric acid production. Suitable for applications with limited space, they effectively control fluid flow (opening, closing, and throttling), withstand high pressures and temperatures, and resist corrosion, making them a critical component for ensuring the stable operation of industrial processes.
