A 2-way butterfly valve is a type of butterfly valve designed with two ports—an inlet and an outlet—that controls the flow of fluid through a pipeline by rotating a disc within the valve body. It provides a straightforward open or close function, regulating flow efficiently with minimal pressure drop. Typically operated manually, pneumatically, or hydraulically, 2-way butterfly valves are favored for their compact size, quick operation, and cost-effectiveness. They are widely used in applications such as water distribution, chemical processing, and HVAC systems, where simple on/off or throttling control is required in a reliable and durable valve solution.
