Performance Excellence of Fully Welded Ball Valves

1. Engineered for no maintenance, adjustment, or lubrication, these valves are easy to install and ensure reliable long-term operation with low running costs. The surface, treated with advanced spraying technology, is both lustrous and beautiful, positioning it as a leader in the Chinese market.
2. The plastic-sprayed surface ensures a stunning lustre, leading the market in China. The welded valve body construction means there is no external leakage, making the valve lightweight and easy to insulate.
3. The operating handle is designed for easy removal and reinstallation in different directions.
4. The valve seat combines a carbon fiber reinforced PTFE seal ring with a disc spring, providing excellent adaptability to pressure and temperature changes, ensuring no leakage within the marked pressure and temperature ranges.
5. The seal ring and disc spring composition ensures high adaptability to pressure and temperature changes, preventing any leakage within the specified ranges.
6. Utilizing advanced computerized testing, the ball processing achieves high precision, ensuring superior performance.
7. With valve body material identical to the pipe material, there are no uneven stresses, no deformation from seismic activity or heavy vehicles, and the pipe remains resistant to aging.
8. The integral fully welded design includes equal and variable diameter channels, fixed and floating balls, a double piston effect sealing system, and automatic injected sealant type bearings.
9. To prevent static electricity, steel balls and springs are integrated between the stem and ball and between the stem and stuffing box, ensuring all parts remain conductive and allow current to pass, thereby releasing static electricity. This not only prevents fire and corrosion but also enables temporary cut-off for timely maintenance.
10. The stem's anti-disengagement feature is designed to counter the disengagement force generated by internal valve pressure, ensuring the stem remains securely in place.
11. Our valves feature a low-friction material thrust washer that ensures effortless pressure application against the stem, transforming the stem into a reliable torque transmitter, enhancing performance and longevity.

Innovative Applications of Fully Welded Ball Valves

1. City Gas Networks: Ideal for gas output pipelines, main lines, and various branch supply pipelines, ensuring seamless and safe gas distribution.
2. Central Heating Systems: Perfect for large heating equipment output pipelines, main lines, and branch lines, guaranteeing efficient and consistent heating.
3. Heat Exchangers: Designed for the effective opening and closing of pipelines and various circuits, offering superior control and reliability.
4. Steel Plants: Essential for managing various fluid pipelines, selective waste gas discharge pipelines, gas and heat supply pipelines, and fuel supply pipelines, optimizing plant operations.
5. Versatile Industrial Equipment: Suitable for diverse heat treatment pipelines, industrial gas, and heat pipelines, ensuring high performance in all industrial applications.
