Fully Welded Ball Valve
Specification:
1. Design standard: API 6D, API 608, ISO 17292
2. Pressure range: CLASS 150-2500 LB
3. Nominal diameter: NPS 2-60 Inch
4. Body material: Carbon steel, Stainless steel, Duplex stainless steel, Alloy steel, Nickel alloy
5. End connection: RF, RTJ, BW
6. Mode of operation: Lever, Gearbox, Electric, Pneumatic, hydraulic device, Pneumatic-hydraulic device
7. Main features: The valve body joint is fully welded which eliminates external leakage through the body joint. The valves are especially suitable for long-distance buried pipelines with rigorous service conditions, such as city gas, city heating, petrochemical plants and etc.
Product features
