A cast iron wafer-type handle butterfly valve is a type of valve that is used to regulate or control the flow of fluids through a pipeline. It's called a wafer type because it has a wafer-like shape, which allows it to sandwich between two flanges in the pipeline.
The cast iron wafer-type butterfly valve is made of cast iron, which is a durable and corrosion-resistant material. The handle is opened or closed the valve, and it's easily operated. The butterfly valve gets its name from the disc-shaped component inside the valve, which resembles a butterfly.
When the handle is turned, the disc rotates around an axis perpendicular to the pipeline, allowing the fluid to flow through or be blocked by the valve. The butterfly valve is commonly used, such as water systems, HVAC systems, and food and beverage processing.
