General Purpose Butterfly Valves
General-purpose butterfly valves are versatile components used in fluid control systems to regulate and control the flow of various liquids and gases. These valves feature a disc-shaped closure element, known as the butterfly disc, which rotates on a central axis to control the flow passage. General-purpose butterfly valves are popular due to their compact design, lightweight construction, and ease of operation. They offer quick and efficient shut-off capabilities and can handle significant flow rates with minimal pressure drop. These valves are widely used in industries such as water treatment, HVAC, chemical processing, and industrial applications where reliable flow control and cost-effective solutions are required. With manual or automated operation options, general-purpose butterfly valves provide a reliable and economical choice for a wide range of fluid control applications.

High Performance Butterfly Valves
High performance butterfly valves give tighter shutoff, higher pressure ratings and longer life than standard resilient-seated butterfly valves. Offset disc designs reduce seat wear and torque.
High Performance Valve Types
- Double offset valves – soft and fire-safe seats
- Triple offset valves – metal-seated zero leakage
- Wafer and lug bodies – ANSI Class 150 and 300
- Automated packages – actuators and controls
Where They're Used
Typical uses include steam, hydrocarbons, chemicals and power generation, where gate or ball valves would be heavier or more expensive. Specify size, class, media, temperature and operator.
Centro supplies high performance butterfly valves and automation.

PTFE Lined Butterfly Valves
PTFE (polytetrafluoroethylene) lined butterfly valves offer chemical resistance and reliability in fluid handling systems. Featuring a PTFE lining, these valves provide superior protection against corrosion and are compatible with a wide range of aggressive chemicals and high-purity fluids. The butterfly valve design ensures smooth flow control and tight shut-off, making them well-suited for applications where precise regulation of flow rates is essential. PTFE-lined butterfly valves find extensive use in industries such as chemical processing, water treatment, and pharmaceuticals, where maintaining product purity and preventing contamination is critical. Their durable construction and ability to withstand harsh operating conditions make them a trusted choice for ensuring efficient fluid handling and optimal performance in demanding environments.

FAQS
- A butterfly valve is a quarter turn valve that uses a rotating disc to control or isolate flow in a piping system. The valve opens and closes quickly and is commonly used in large diameter applications.
- Butterfly valves are used in water and wastewater treatment, HVAC systems, chemical processing, food and beverage, fire protection, and general industrial piping systems.
- Common types include wafer style, lug style, and flanged butterfly valves. They are also classified as concentric or high performance (double offset) designs.
- Butterfly valves are commonly made from cast iron, ductile iron, stainless steel, and carbon steel. Seat materials may include EPDM, Buna N, Viton, or PTFE depending on application needs
- Wafer valves fit between flanges and are held in place by flange bolts. Lug valves have threaded inserts that allow one side of the piping to be disconnected while the valve remains installed.
