Unmatched Sealing and Flow ControlThe spherical disc butterfly valve stands out with its bubble-tight Class VI shut-off, ensuring zero leakage even under extreme conditions. The spherical geometry optimizes flow and minimizes turbulence, providing outstanding reliability in both standard and demanding process environments.
Exceptional Durability for Tough MediaThis valve's metal-seated construction allows operation with abrasive, high-temperature media such as steam, chemicals, and gases. High-grade alloy and stainless-steel materials, coupled with anti-corrosive body coatings, deliver long service life and resistance to corrosion.
Effortless Operation and MaintenanceEngineered for low operating torque, the valve's unique spherical profile enables easy manual, electric, or pneumatic actuation. Inline serviceability simplifies maintenance, reducing downtime and preserving process efficiency for busy industrial settings.
FAQ's of Spherical Disc Butterfly Valve - Metal Seated:
Q: How does the spherical disc design enhance flow and sealing in this butterfly valve?
A: The precision-engineered spherical disc creates smooth flow pathways and reduces turbulence, resulting in improved flow characteristics. Its design ensures consistent and reliable bubble-tight sealing (Class VI), even under challenging operating conditions.
Q: What sets the metal-seated valve apart for high temperature or abrasive applications?
A: The metal seat is highly resistant to wear, making it ideal for abrasive media such as slurries, chemicals, steam, and gases. It maintains sealing integrity at elevated temperatures up to 450C, where soft-seated valves may fail.
Q: When should I consider using this butterfly valve in my process system?
A: This valve is suitable for processes requiring dependable shut-off, resistance to corrosion, and robust performance at temperatures ranging from -10C to 450C. It's commonly used in industrial, power generation, chemical, water treatment, and oil & gas industries.
Q: Where can this valve be installed, and what connection standards are available?
A: The valve can be installed in diverse industrial environments and is compatible with EN, ANSI, DIN, and JIS end connection standards. Connection options include wafer, lug, and flanged types to suit various piping layouts.
Q: What is the procedure for inline servicing and maintenance of the valve?
A: Thanks to its accessible design, maintenance such as seat or seal replacement can be performed without removing the valve from the pipeline. This minimizes downtime and reduces overall maintenance workload.
Q: How does the valve benefit operators in terms of torque and actuation?
A: The special spherical profile reduces operating torque, making manual, electric, or pneumatic actuation smoother and more energy-efficient. This is particularly advantageous in large-diameter or high-pressure applications.
