Natural Gas Welded Ball Valve: Applications, Features, Installation, and Maintenance

✦ Urban Gas Supply: Perfect for gas output pipelines, main trunk lines, and various branch supply pipelines, ensuring stable gas delivery to residential and commercial zones.

✦ Centralized Heating Systems: Essential for output pipelines, main trunks, and branches of large-scale heating equipment, enabling efficient heat distribution.

✦ Heat Exchangers: Utilized to open or close pipelines and individual circuits, precisely controlling heat exchange processes.

✦ Steel Plants: Suitable for various fluid pipelines, exhaust gas discharge pipelines, gas and heat supply pipelines, as well as fuel supply pipelines.

✦ Various Industrial Equipment: Applied in heat treatment pipelines and various industrial gas/heat pipelines, meeting diverse industrial fluid control needs.

✦ Integral Welded Structure: Eliminates the risk of external leakage, ensuring maximum sealing reliability.

✦ Adaptable Valve Seat: Composed of a carbon fiber-reinforced Teflon sealing ring and a disc spring, it adapts strongly to pressure and temperature changes. No leakage occurs within the rated pressure and temperature range.

✦ Precision-Machined Ball: Advanced computerized inspection systems monitor the ball’s manufacturing process, achieving ultra-high machining precision.

✦ Pipeline-Matched Valve Body Material: The valve body uses the same material as connected pipelines, avoiding uneven stress. It also resists deformation from earthquakes or vehicle traffic above ground and ensures long-term aging resistance.

✦ Zero-Leakage Sealing Ring: Made of RPTFE with 20% carbon content, the sealing ring guarantees 100% leak-free performance.

✦ Direct Burial Capability: Can be buried directly underground without large valve wells. Only small shallow wells are needed on the ground, greatly reducing construction costs and time.

✦ Customizable Design: The length of the valve body and the height of the valve stem can be adjusted according to pipeline construction and design requirements.

✦ Smooth Operation: Ultra-precise ball machining ensures light, smooth operation without unwanted interference.

✦ High Pressure Resistance: Crafted from premium raw materials, it withstands pressure above PN25.

✦ Compact & Attractive Appearance: Compared to same-spec products in the industry, the valve body is smaller and more aesthetically pleasing.

✦ Long Service Life: Under normal operation, its service life exceeds 15 years.

✦ Pre-Installation Checks: Before installation, inspect the valve for any damage during transportation. Verify that the valve model, specifications, and pressure rating match the pipeline requirements. Also, check the sealing performance of the valve.

✦ Pipeline Preparation: Ensure the pipeline is clean and free of debris, rust, or other contaminants that could damage the valve or affect sealing. Align the pipeline accurately with the valve to avoid excessive stress during welding.

✦ Welding Process: When welding the valve to the pipeline, use appropriate welding techniques and materials that match both the valve and pipeline materials. Avoid overheating the valve during welding, as this can damage internal components. It is recommended to use cooling measures if necessary.

✦ Post-Welding Inspection: After welding, inspect the welds for integrity. Check for any leaks using appropriate testing methods, such as pressure testing. Ensure the valve operates smoothly after installation.

✦ Periodic Inspections: Conduct regular visual inspections to check for signs of leakage, corrosion, or damage. Inspect the valve stem for smooth operation and check the sealing performance.

✦ Lubrication: Apply appropriate lubricants to the valve stem and other moving parts at regular intervals to ensure smooth operation and prevent wear.

✦ Cleaning: Keep the valve and surrounding area clean. Remove any debris or contaminants that could interfere with valve operation.

✦ Pressure Testing: Perform periodic pressure tests to verify the valve's sealing performance and ensure it can withstand the rated pressure.

✦ Replacement of Worn Parts: If any components, such as sealing rings or springs, show signs of wear or damage, replace them promptly to maintain the valve's performance.
