Technical Characteristics

A butterfly valve disc is a crucial component of a butterfly valve, which is a type of quarter-turn valve used to regulate the flow of a fluid, typically in a pipeline. The disc, also known as the butterfly, is the part of the valve that controls the flow by turning or pivoting within the valve body. The disc can be designed in such a way that it allows flow in one direction only (known as a unidirectional or one-way valve) or in both directions (bidirectional). Depending on the design of the butterfly valve, the disc can be of the lug or wafer style. The lug style has threaded inserts on the valve's outer edges for bolting it to the pipeline flanges. The wafer style is thinner and fits between two flanges, held in place by the pressure of the system.

Butterfly valves are commonly used in applications in the food, pharmaceutical, and chemical industries where flow needs to be shut off or controlled quickly and efficiently. They are typically used for large diameter pipes and are preferred for their simple, compact design and cost-effectiveness.
