Buried Fully Welded Ball

Hebei Tongli Automatic Control Valve Manufacturing Co., Ltd produces buried fully welded ball valves designed for underground installation in heating, gas and industrial piping systems. These valves eliminate the need for tall valve wells, reducing construction costs and improving safety by preventing operator exposure to harmful gases or debris. The fully welded design integrates the valve directly into the pipeline, removing the need for flanges, bolts or gaskets, which enhances sealing reliability and longevity.

The ball valve’s construction uses a floating ball design, where the ball is held in place by two spring-loaded seats that compensate for pressure and temperature variations. This ensures a tight seal even in the presence of minor impurities or debris in the medium. Typical materials for the body include carbon steel (ASTM A216 WCB) or stainless steel (ASTM A351 CF8), with a standard pressure rating of PN16 to PN40 and temperature range of -29°C to 200°C. The valve’s buried design also allows for direct welding to the pipeline, which improves structural integrity and reduces leakage risks.

These valves are used in city gas distribution networks, central heating systems, heat exchangers, steel plants and industrial equipment for fluid, gas and heat transfer applications. The supplier, based in Shijiazhuang, Hebei Province, highlights advantages such as light weight, ease of insulation and a typical warranty of 10 years due to the valve’s robust construction. Buyers should confirm compatibility with their piping material, pressure class and medium type, as well as any custom mounting dimensions.

Hebei Tongli Automatic Control Valve Manufacturing Co., Ltd is based in Room 1611, Diamond Square B Building, Shijiazhuang, Hebei Province, China. The company specialises in the development and production of control valves, with a focus on innovative designs for underground and industrial applications. The supplier holds a harbor trust tier and imported supplier tier, though current response metrics are not available, indicating buyers should establish direct contact for inquiries.

The company’s product line centres on fully welded ball valves, which are engineered to address challenges in traditional valve systems, such as debris accumulation, sealing failures and high material consumption. The profile does not provide details on production capacity, certifications or export markets, so buyers are advised to request technical specifications, quality control processes and references to validate the supplier’s capabilities.
