Ductile Iron Flanged Butterfly Valves

It certainly does. All of our actuated valves come complete with a full set of operations and maintenance manuals from both the valve and actuator manufacturers.

Flanged connections provide secure installation, easy alignment, and strong sealing in larger pipeline systems. They are especially beneficial in high-flow or critical service lines where stability and maintenance access are priorities.

Yes we can. If you cant find what you are looking for on the website get in touch. We have valve switch boes for all zoned and safe areas including LED visual indication.

Ductile iron flanged butterfly valves are commonly used to isolate or regulate flow in water, HVAC, chemical processing, and general industrial pipeline systems. They are ideal for large diameter pipelines where lightweight construction and reliable shut-off are important.

Maintenance is typically minimal, but regular inspection is recommended to check the seat condition, disc wear, and fastener tightness. Keeping the valve clean and operating it periodically helps prevent seizure and ensures reliable long-term performance.

Ductile iron offers higher strength, impact resistance, and flexibility compared to traditional cast iron. This makes the valve more durable under pressure, vibration, and temperature changes, reducing the risk of cracking in demanding applications.

Most ductile iron flanged butterfly valves are manufactured to PN10, PN16, or ANSI 150 pressure ratings. The exact rating depends on the design standard and seat material, so it’s important to match the valve to the system’s operating pressure.

They can be suitable when paired with the correct internal coating and seat material. Epoxy coatings and resilient seats such as EPDM or PTFE help protect the valve body and allow it to handle a wide range of water and mild chemical applications.

Great. The Namur standard interface is perfect for direct mounting a pilot solenoid valve. We can supply this actuated valve for you with or without a solenoid valve.
