Manual Flanged High-Performance Butterfly Valve

Features

• High-Performance Sealing: Utilizes advanced sealing materials and designs to achieve bubble-tight sealing, surpassing Class VI standards. This ensures minimal leakage and reliable performance in various applications.
• Double Eccentric Design: Minimizes sealing face friction and extends valve life. This design allows for smooth operation and reduces wear on the sealing surfaces.
• Durable Construction: Made from high-quality materials such as stainless steel, carbon steel, and alloy steels, ensuring longevity and resistance to harsh operating conditions.
• Adjustable Stem Packing: Easy access and field serviceable, allowing for low fugitive emissions and extended service intervals.
• Blowout-Proof Stem Design: Prevents stem blowout due to connection failure between disc and stem, enhancing safety and reliability.
• Easy Maintenance: Features interchangeable parts and on-site replaceability of defects with general tools. This simplifies maintenance procedures and reduces downtime.
• Versatile Applications: Suitable for a wide range of industries and media, including acids, alkalis, corrosive chemicals, gases, hydrogen, oxygen, and water.

Applications

• Chemical Industry: For handling corrosive chemicals, acids, and alkalis.
• Oil and Gas: In pipelines, refineries, and natural gas processing facilities.
• Power Generation: In steam and water systems of power plants.
• Water and Wastewater Treatment: For controlling water flow in treatment plants.
• Pharmaceuticals: In applications requiring high-purity and sterile conditions.
• Food and Beverage: For processing and packaging applications where hygiene is critical.

Installation and Maintenance

• Pre-Installation: Ensure the valve is clean and free from foreign objects. Check all connecting pipe bores and connection areas for flush, rust, and foreign bodies.
• Installation: Install the valve in the correct orientation, ensuring flow direction matches the valve's preferred direction. For double-flanged valves, align with ASME B16.5 raised-face flanges.
• Maintenance: Regularly inspect and clean the valve. Check the condition of seals and replace if necessary. Adjust stem packing to maintain proper sealing. Lubricate moving parts as needed.
• Storage: Store in a dry, well-ventilated area away from direct sunlight and corrosive substances.
