Wafer Butterfly Valves

Wafer butterfly valves are pivotal components in fluid control systems. Recognized for their compactness, lightweight nature, and straightforward installation, they serve a crucial role in regulating fluid flow across a variety of industries. Here’s a closer look at these valves, their design, and their applications.



    • Shape and Function: Named “wafer” because of their thin design, these valves consist of a central disc (the butterfly) mounted on a spindle. This disc rotates, controlling the flow of fluid through the valve.
    • Installation: Their body is sandwiched between two flanges in a pipeline, held in place by bolts, ensuring a secure and tight seal.


    • Space Efficiency: Their slim structure ensures they’re ideal for installations with limited space.
    • Light and Durable: Made typically from materials like ductile iron, these valves are both lightweight and robust.
    • Optimized Flow: Their design results in a minimal pressure drop when fully opened, ensuring efficient fluid movement.
    • Rapid Response: Operating on a quarter-turn principle, they can swiftly open or close, which is crucial for on/off control applications.
    • Cost Advantage: Simplicity in design coupled with durability translates to cost-effectiveness.


    • HVAC Systems: Their efficiency in regulating hot and cold water flow makes them staples in heating, ventilation, and air conditioning setups.
    • Water Management: Their cost-effectiveness and installation ease place them at the forefront in water supply, treatment plants, and irrigation systems.
    • Chemical Handling: Their ability to control flow efficiently makes them ideal for chemical processing plants, especially with corrosive fluids.
    • Food Production: Their design, which allows for easy cleaning, is crucial for the food and beverage industry, ensuring hygiene.
    • Fire Safety: Their rapid operation ensures they’re vital components in fire protection systems for quick and reliable shutoff control.


Wafer butterfly valves are invaluable tools in fluid flow regulation, combining efficiency, cost-effectiveness, and reliability. For professionals in industries ranging from HVAC to food production, these valves remain integral for effective fluid handling and management.
