Double Eccentric High Performance Stainless Steel Butterfly Valve

Performance Features

• High-Pressure and High-Temperature Resistance: The valve is designed to handle high-pressure environments and resist high temperatures effectively, making it ideal for industries such as chemical processing and power generation.
• Superior Sealing Power: The unique design ensures superior sealing capabilities, minimizing the risk of leakage and making it suitable for applications where zero leakage is critical.
• Reduced Wear and Tear: The double eccentric design reduces operating torque, minimizing wear and tear on components and enhancing the valve's longevity.
• Corrosion Resistance: The valve is equipped with features that enhance its resistance to corrosion, such as a dry shaft with multiple O-ring seals and surface protection coatings like rilsan or halar.
• Long Service Life and Ease of Maintenance: The robust construction and design contribute to the long service life of the valve, with minimal maintenance requirements and easy repair.

Advantages

• Leak-Free Design: The optimized design ensures tight shutoff and prevents leaks, even under high-pressure conditions.
• Low Maintenance: Features like replaceable shaft seals, low-friction bearings, and a durable coating require minimal maintenance over the valve's lifespan.
• Versatility: The valve can be used in both underground and above-ground applications and is bi-directional, making it suitable for various flow control needs.
• Cost-Effective: More affordable than gate valves, especially in large diameters, making it a cost-effective solution for many applications.
• Long-Term Durability: The robust design, combined with high-quality sealing materials and protective coatings, ensures that the valve can withstand harsh conditions.

Application Scenarios

• Water Supply and Distribution: Ideal for use in water pipelines, sewage treatment plants, and stormwater management systems.
• Wastewater Treatment: Offers an excellent combination of durability, tight sealing, and ease of maintenance in wastewater treatment facilities.
• Chemical Processing and Power Generation: Suitable for controlling the flow of steam, water, and hazardous chemicals in chemical processing plants, refineries, and power plants.
• Oil and Gas: Used in oil and gas pipelines and processing plants to control the flow of liquids and gases under high pressure and temperature conditions.
• HVAC Systems: Regulates the flow of air or fluid in heating, ventilation, and air conditioning systems.
