Butterfly Valves
Butterfly Valves play a crucial role in ensuring precise flow control across a wide range of industrial applications, including the management of liquids, gases, and slurries. Our selection of Butterfly Valves encompasses both wafer and lug designs, engineered with high-performance 316 stainless steel disks and EPDM seats to guarantee robust, leak-proof operation. They offer excellent resistance to abrasion, oxidation, heat aging, ketones/esters, and water, handling temperatures up to 110°C.
Constructed from durable ductile iron, these valves are both lightweight and strong, optimizing space without sacrificing reliability. With a choice between lever-operated and gear-operated mechanisms, users can select the ideal option based on their specific operational needs. Lever-operated valves are known for their straightforward and quick operation, making them suitable for applications where frequent adjustments are necessary. In contrast, gear-operated valves offer precise control, ideal for systems requiring fine-tuned adjustments, such as in chemical processing or large-scale water treatment plants.
Available in multiple sizes and pressure ratings, also Watermarked. Our Ductile Iron Butterfly Valves excel in both general and severe service environments, offering exceptional performance and longevity in real-world applications such as municipal water treatment and distribution, HVAC systems, mining, brewing, industrial chemical handling and many more.
Butterfly Valves: Wafer & Lugged Styles / Lever & Gear Operated
Explore our range of Certified Ductile Iron Butterfly Valves, engineered for efficient fluid control in diverse applications.
Wafer Butterfly Valves
The wafer butterfly valve style is compatible with most international flange standards, including AS2129, BS10, ANSI, DIN, and JIS. Available in sizes from 50mm (2") to 300mm (12") or 350mm (14") to 600mm (24") in the Watermark range, these valves are ideal for inline service, securing to the pipeline with flanges on either side. The 50mm to 300mm EPDM version is WaterMark certified (Certificate No: WMKA25460) and features a durable blue Akzo Nobel Paint coating.
Lugged Butterfly Valves
The lugged butterfly valve style also ranges from 50mm (2") to 300mm (12") or 350mm (14") to 600mm (24") in the Watermark range, and includes lugs cast into the body, allowing for flange fixing on one side. This design enables mounting at the end of a pipeline without requiring a downstream flange. Like the wafer style, the EPDM version is WaterMark certified (Certificate No: WMKA25460) and protected by a blue Akzo Nobel Paint coating.
