Product introduction:
With superior performance and reliable quality, fully welded ball valves have become core equipment for underground
projects in urban gas transmission and distribution networks, central heating systems, natural gas long-distance pipelines,
and pressure regulating stations. After 30 years of technical expertise, continuous R&D innovation, and process optimization,
product performance has been continuously breakthrough, gaining wide trust and high recognition in energy infrastructure
construction across more than 30 countries globally. The valve body adopts an integrated full-welding process, fundamentally
eliminating potential leakage hazards from traditional connection methods and achieving leapfrog upgrades in both internal
and external sealing performance of the valve. The valve body is carefully selected from high-quality steel pipes or A105
forgings, and through precision forging and strict testing, it ensures that the valve body is free of defects such as sand holes
and air pockets, completely eliminating leakage risks. This design not only significantly reduces sealing maintenance costs
in engineering construction but also greatly shortens the construction period by minimizing hidden danger inspections in
installation and debugging, providing efficient and safe solutions for energy transmission projects.

Product features:
1. Fully Welded Body: Integrally welded to eliminate external leakage, with a compact structure for easy installation.
2. Low Torque Operation: Equipped with PTFE self-lubricating bushings to minimize friction, ensuring effortless opening
and closing.
3. Double Block and Bleed (DBB): Allows discharge of media from the valve body when closed under pressure, ensuring
safety.
4. Dual Piston Sealing: Both valve seats are pressure-actuated for sealing; if the upstream seat leaks, the downstream
seat automatically engages to stop leakage.
5. Reliable Sealing: Floating seat + spring preload, combined with particle-resistant composite seals, achieves zero
leakage and adapts to various working conditions.
6. Emergency Sealing System: - Inject sealant to repair damaged seals under pressure. - Clean and lubricate sealing surfaces when handling particulate media. - Bottom check design prevents leakage from the valve base.
