Ductile iron is a great material for butterfly valves due to its rigidity. It will not lose its shape even under extreme pressures. Butterfly valves are a convenient, easy-to-operate valve that has a 90-degree range of motion from open to close.
The name "butterfly" valve refers to the wing-like appearance of the disk on either side of the valve's central stem. These valves are typically operated with a quarter-turn handle or an automatic actuation system. The ductile iron butterfly valves we carry are available in a wide range of sizes and configurations.
