36 inch butterfly valves are large-diameter valves designed to control and isolate substantial fluid flow in industrial and municipal piping systems. They provide a compact and lightweight alternative to more cumbersome valve types while still accommodating high flow rates. Well suited for low to medium pressure applications, these valves offer smooth operation, reliable shutoff, and minimal maintenance. Common applications include water treatment plants, HVAC systems, cooling water circuits, and industrial process pipelines, where 36 inch butterfly valves are appreciated for their efficiency, durability, and ease of installation.
