Function

The 4″ Wafer Butterfly Valve operates by using a rotating disc within the valve body. The butterfly disc has a central hole, and when the valve is open, the hole aligns with the flow path, allowing fluid to pass through. When the valve is closed, the disc rotates 90° to block the flow and provide a tight seal.

The wafer-style design eliminates the need for additional flanges, which reduces both installation time and cost. The full-bore design ensures that when the valve is open, fluid flows without significant pressure drop. The valve’s reliable sealing system prevents leakage, making it ideal for both on/off and modulating control applications.

This valve features a butterfly disc that rotates 90 degrees to either allow or block fluid flow. The wafer-style design ensures ease of installation and removal, as it fits directly between flanges without the need for additional flanges or gaskets. The valve is constructed from corrosion-resistant materials, including stainless steel, ductile iron, and cast iron, ensuring durability and long-term performance even in harsh environments.
