ductile iron butterfly valve manufacturers in USA

 

SVR Global is one of the leading 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

Key parts of ductile iron butterfly valves
• Valve body manufactured from ductile iron with corrosion-resistant coating
• Disc made of stainless steel, ductile iron, or coated alloy for durability
• Seat available in EPDM, NBR, PTFE, or metal options depending on service
• Stem/shaft providing torque transmission and operational reliability
• Bearings and bushings ensuring smooth disc rotation
• Actuator or hand lever for manual or automated operation
