The Definitive Guide to Flange Butterfly Valves: Why Choose HONGON?

 In industrial piping systems where space is limited and robust connections are mandatory, the flange butterfly valve​ is the engineer's go-to solution. Unlike wafer-style valves, flanged valves are designed with built-in connection points, offering superior strength and easier installation in high-stress environments. At HONGON (Shanghai Hongon Machinery Technology Co., Ltd.), we specialize in manufacturing high-performance flange butterfly valves that combine precision engineering with unmatched durability.

Since our establishment in 2007, we have leveraged our expertise in CNC machining​ and automated production​ to become a leading supplier of industrial valves. Our flange butterfly valves are a cornerstone of our product line, trusted by clients in over 40 countries.

πŸ”§ What is a Flange Butterfly Valve?

A flange butterfly valve​ is a quarter-turn valve that uses a disc rotating on a shaft to control flow. Its defining feature is the integral flanges​ on the valve body, which allow it to be bolted directly between two pipe flanges (raised face or ring joint) using standard bolts.
  • Advantage over Wafer Type:​ Flanged valves are heavier and stronger, making them ideal for high-pressure applications, end-of-line service, or situations where the pipe might experience significant stress or vibration.
  • Bi-directional Sealing:​ Our flanged valves are engineered to provide a tight shut-off regardless of flow direction.

🏭 The HONGON Manufacturing Advantage

As a vertically integrated manufacturer, HONGON ensures every flange butterfly valve meets the highest standards.
  • Robust Construction:​ We utilize high-strength materials​ like Ductile Iron (GGG40), Cast Steel (WCB), and Stainless Steel (CF8M) to construct the valve body, ensuring it can withstand high pressures and mechanical shocks.
  • Precision Sealing:​ Whether fitted with soft seats (EPDM, NBR, PTFE) for water/gas or our patented all-metal seated design​ for high-temperature steam and oil, our valves guarantee zero leakage.
  • Automated Production:​ Our BHC automated flexible production lines​ ensure perfect flange face alignment and drilling, guaranteeing hassle-free installation.

🌍 Applications Across Industries

Our flanged butterfly valves are critical components in:
  • Water & Wastewater Treatment:​ Main isolation valves for large-diameter pipelines.
  • Power Generation:​ Cooling water systems and auxiliary steam lines.
  • Oil & Gas:​ Fuel gas lines and pump station manifolds.
  • HVAC & Fire Protection:​ Reliable shut-off for large-scale building services.
