Flanged butterfly valve
The Flanged Butterfly Valve is an advanced valve solution designed to cater to a wide variety of industrial applications. It combines the efficiency and compactness of a butterfly valve with the robust and secure connection of a flanged design, offering superior control over fluid flow in various systems.
Constructed from high-quality materials, the Flange Butterfly Valve is engineered to withstand extreme temperature and pressure conditions. Its key feature is the flanged design, which involves a disc rotating on an axis to control the fluid flow. The flanges on either side of the valve allow for easy installation and secure attachment to the pipeline, preventing any potential leakage.
One of the key advantages of this valve is its straightforward operation. The valve features a disc that pivots on a rod. When the rod is rotated by a handle or actuator, it opens or closes the valve, thus controlling the fluid flow. This simple operation makes the valve user-friendly and easy to maintain.
The Flanged Butterfly Valves can come equipped with a manual, pneumatic, hydraulic, or electric actuator, depending on your specific needs. Manual actuators are operated using a handwheel or lever, while automated actuators provide remote operation and increased safety.
The valve features a full or reduced bore design, providing minimal resistance to fluid flow when fully open, maximizing flow rates, and reducing pressure drop across the valve. This makes it an ideal choice for systems requiring high flow rates.
The body of the Flanged Butterfly Valve is typically made from metals like stainless steel, cast iron, or bronze, providing excellent resistance to corrosion and ensuring a long service life. The internal components of the valve are precision-engineered to provide a tight seal when closed, preventing any leakage and maintaining the integrity of the system.
In conclusion, the Flanged Butterfly Valve is an efficient, durable, and versatile valve solution suitable for a diverse range of industrial applications. Its flanged design, simple operation, and robust construction make it a reliable choice for controlling the flow of fluids in your system.
Double flanged butterfly valve features a bonded liner extending over the flanges. The double flange design is suitable for high pressure loading and for use in heavy industry, shipbuilding, severe vacuum applications and water treatment industry like potable water, water treatment and wastewater applications.
