What Is a Wafer Butterfly Valve

A wafer butterfly valve is a type of quarter-turn valve designed to regulate or isolate flow in piping systems. The valve is installed between two flanges using bolts that pass through the entire assembly, making it compact and lightweight compared to flanged butterfly valves.

Wafer butterfly valves are widely used in water treatment, HVAC systems, oil and gas pipelines, and general industrial applications due to their simple structure and cost efficiency.

Cast Iron Wafer Butterfly Valve Raw Material

When selecting materials for industrial water valves, cast iron wafer butterfly valves stand out as a preferred choice due to their strength, reliability, and cost-effectiveness. 

  ● Excellent durability and pressure resistance: High pressure cast iron wafer butterfly valve offers high compressive strength, making it ideal for low to medium pressure fluid systems, including water distribution, HVAC, and wastewater management.

  ● Corrosion protection: With fusion bonded epoxy coating, our corrosion-resistant cast iron butterfly valves ensure long-lasting protection even in humid or mildly aggressive environments.

  ● Cost-effective for large-scale projects: Compared to stainless steel or exotic alloys, low cost cast iron wafer butterfly valve offers a more affordable solution while still delivering reliable sealing and operation in industrial piping systems.

Wafer vs Lug Butterfly Valve

Compared with lug butterfly valves, wafer butterfly valves are more economical and lighter in weight. Wafer design is suitable for systems where downstream removal is not required, while lug type valves allow end-of-line service.
