NSV A105 Full Welded Ball Valves with 100mm nipples have been shipped. Featuring A105 forged steel bodies and a fully welded structure, they are designed for city gas and district heating systems to ensure zero leakage and long-term stability.
The fully welded body eliminates external leakage, making it ideal for direct burial in harsh environments and the extended 100mm nipple design perfectly accommodates deep burial or thick insulation layers.
Combined with bi-directional sealing technology, it provides excellent shut-off performance regardless of flow direction, significantly reducing maintenance costs.
Every valve undergoes rigorous pressure testing and inspection before leaving our factory.
NSV remains committed to delivering precision-engineered quality that supports safe and efficient fluid transport across global industrial pipelines.
