This Carbon Steel Fully Welded Ball Valve is made of Q235B/Q355B high-quality carbon structural steel plate with CNC rolling and fully automatic one-piece welding. It is equipped with full-series polymer soft seal structure, specially designed for PN10-PN25 (Class150) low pressure working conditions. Covering full sizes DN50-DN1200, it strictly complies with GB, ANSI/ASME and API 6D standards, eliminating external leakage risk from the root. It is the core on-off equipment for low pressure underground pipe networks such as urban gas, district heating and municipal water supply & drainage.

The Butt Welded Ball Valve is a high-performance valve designed for critical applications that require a seamless, leak-free connection between the valve and the pipeline. This valve uses butt-weld connections that are fused directly into the pipeline, eliminating the need for flanged or threaded joints. As a result, it provides a permanent and durable seal, ensuring reliable performance in high-pressure, high-temperature, and harsh environments. The Butt Welded Ball Valve is widely used in various industrial sectors, including oil and gas, chemical processing, petrochemical, power generation, and HVAC systems. It is an ideal solution for applications where safety, reliability, and minimal...

The Socket Welded Ball Valve is a highly reliable and durable valve designed for use in high-pressure systems. This valve features a socket weld connection, which ensures a secure, leak-tight seal, making it suitable for applications where safety, reliability, and performance are critical. The valve body is typically made from stainless steel or carbon steel, offering excellent corrosion resistance and mechanical strength. The socket weld design is particularly beneficial for systems operating under high pressure and severe conditions, such as oil and gas pipelines, chemical processing, and power generation.

This Buried Full Welded Ball Valve is a special on-off valve tailor-made for direct underground burial working conditions. Its core adopts an integrally welded valve body made of Q235B/Q355B high-quality carbon structural steel plate with CNC rolling and fully automatic one-piece welding, without split connections, bolt fastenings and aging-prone gaskets, completely eliminating the risk of valve body external leakage from the root.

The Electric Fully Welded Ball Valve is designed for low-pressure and low-temperature applications where reliable and secure flow control is critical. Constructed from welded steel plates such as Q235, Q345, and 16Mn, this valve offers a robust, leak-proof design that is ideally suited for district heating systems, municipal heating pipelines, and water distribution systems. With PTFE sealing for optimal leak protection, this valve provides long-lasting performance in environments with pressures up to PN25 and temperatures up to 150°C.

The 3-piece butt welded ball valve is a high-performance valve designed for demanding industrial applications requiring secure and durable pipeline connections. Featuring a three-piece body construction, this valve provides excellent maintainability and sealing performance. ...
