Butterfly Valves - Flowseal
We provide a broad range of high-performance butterfly valves engineered to meet the demands of various industrial applications. Available in multiple sizes, materials, and configurations, our valves are designed for efficient flow control, long-term durability, and ease of installation and maintenance.
Whether you're working within space-constrained systems, need reliable isolation in critical applications, or require robust solutions for corrosive or high-pressure environments, we have the right valve for your specifications.
Our Butterfly Valve Offerings Include:
- Wafer Butterfly Valves – Slim, lightweight design ideal for low-pressure applications and compact piping layouts.
- Lug Butterfly Valves – Designed for easy installation and line maintenance, suitable for dead-end service.
- Double-Offset Butterfly Valves – Precision sealing and reduced wear, perfect for high-temperature and moderate-to-high pressure systems.
- Triple-Offset Butterfly Valves – Metal-seated for maximum durability and zero leakage, ideal for critical and corrosive applications.
- Resilient Seated Butterfly Valves – Excellent corrosion resistance, making them ideal for water treatment, chemical processing, and general utility use.

- 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.
