Item Number:

Wafer butterfly valve is a type of quarter-turn valve that is typically used in industrial applications to regulate or isolate the flow of fluids or gases. It features a disc-shaped closure element that is mounted on a shaft and rotates 90 degrees to open or close the valve. The valve's compact design allows it to be sandwiched between two flanges without the need for additional mounting hardware. Wafer butterfly valves are commonly made from materials such as stainless steel or cast iron and are suitable for a wide range of applications including water, chemicals, and gases.
