SVR Global is one of the leading "https://www.svrglobal.net/product-category/lug-butterfly-valve/">ductile iron butterfly valve manufacturers in USA providing cost-effective and durable flow control solutions for industries such as water treatment, oil gas, petrochemicals, power generation, marine, and HVAC systems. Our valves are manufactured in compliance with API, ASME, AWWA, and ISO standards, ensuring reliable performance, corrosion resistance, and long service life. With a strong supply network across Houston, Chicago, Los Angeles, New York, and Dallas, we support EPC contractors and end-users across the country with high-quality butterfly valves.
A ductile iron butterfly valve is a quarter-turn valve designed to regulate, start, or stop the flow of media within a pipeline. The body is made from ductile iron, a material known for its superior tensile strength and impact resistance compared to cast iron, making it more durable in heavy-duty service. With an epoxy-coated finish, these valves offer additional corrosion protection, making them suitable for both industrial and municipal applications.
Advantages of ductile iron butterfly valves
• High strength and impact resistance compared to cast iron valves
• Lightweight design, reducing installation time and cost
• Epoxy-coated ductile iron body ensures corrosion resistance and durability
• Quarter-turn operation enables fast opening and closing
• Compact and economical design ideal for large-diameter pipelines
• Suitable for both low-pressure and medium-pressure systems
• Long service life with minimal maintenance requirements
Types of ductile iron butterfly valves -
• Wafer type ductile iron butterfly valve – Compact and lightweight, installed between flanges for general service
• Lug type ductile iron butterfly valve – Allows dead-end service and secure installation for maintenance flexibility
• Double offset ductile iron butterfly valve – Suitable for higher pressure and temperature applications with improved sealing
• Triple offset ductile iron butterfly valve – Zero leakage design for critical services in oil gas and petrochemicals
• Resilient seated ductile iron butterfly valve – Bubble-tight shutoff for water and wastewater systems
• Metal seated ductile iron butterfly valve – Ideal for abrasive and high-temperature service conditions
• Actuated ductile iron butterfly valves – Available with electric or pneumatic actuators for automation
