Waits Bronze Triple eccentric Flange Butterfly Valve adopts triple eccentric design to reduce torque and extend service life. Its aluminum bronze valve body is corrosion/high temperature resistant and equipped with flange connection and multiple drive modes, suitable for petrochemical/energy fluid control. With this triple eccentric structure, the butterfly valve always maintains a tight fit between the butterfly disc and the seal ring during opening and closing.
Welcome to Waits valve, we have selected a variety of commercial and industrial Bronze Triple eccentric Flange Butterfly Valve for you. The lug connection makes it easy to install in the pipeline. Suitable for HVAC, water treatment and chemical processing. They are suitable for almost all industrial processes, including water and sewage treatment, mining, power generation, oil, gas and oil processing, food manufacturing, chemical and plastic manufacturing and many other fields.

Performance Characteristics
Bronze Triple eccentric Flange Butterfly Valve is a gate valve. The gate is in the shape of a butterfly with a center shaft and a disc connected to the center shaft. The disc is located inside the valve body, and the center shaft is connected to the handle outside the valve body. The triple eccentric eccentric butterfly valve is also called a triple eccentric center shaft valve. The composite stainless steel seal ring installed on the butterfly plate realizes a leak-proof design.
Applications
Designed for ballast and cooling systems.
Bronze Triple eccentric Flange Butterfly Valve is suitable for seawater treatment in oil and gas operations and is durable.
Desalination plants
Port infrastructure
The Waits Bronze Triple Eccentric Flange Butterfly Valve excels in sealing performance with its triple-eccentric structure, ensuring minimal wear between the seat and disc while achieving a self-tightening seal that guarantees zero leakage for gas media. It offers good resistance to high temperatures, corrosion, and abrasion, as the aluminum bronze material itself provides robust corrosion and wear resistance, further enhanced by hard-seal structures and surfacing of corrosion-resistant and abrasion-resistant alloy materials, making it suitable for terrible environments in industries like metallurgy, power, petroleum, chemicals, and water supply/drainage for pipelines handling corrosive media. The valve’s stem, designed with a triple-eccentric structure, ensures rational force distribution and low operating torque, enabling easily opening and closing across manual, worm gear, pneumatic, or electric actuation methods. With a well-engineered flow path that offers a large flow area and low flow resistance coefficient, it minimizes pressure loss in the pipeline, reducing system energy consumption and enhancing overall efficiency.
