Full welded ball valve
The Full Welded Ball Valve is a high-performance industrial valve designed for reliable shut-off and flow control in long-distance pipeline systems and demanding industrial applications. Featuring a fully welded valve body structure, this valve eliminates potential leakage points caused by traditional bolted connections, providing superior safety, durability, and long-term operational reliability.
The all-welded design offers excellent pressure resistance, corrosion protection, and mechanical strength, making it especially suitable for buried pipelines, natural gas transmission systems, oil transportation networks, and other critical pipeline applications.
With a full bore flow channel design, the valve provides low pressure loss, high flow capacity, and efficient pigging capability. The advanced sealing structure ensures tight shut-off performance, reduced maintenance requirements, and stable operation under harsh environmental conditions.
Manufactured using advanced welding technology, precision machining, and strict quality control processes, the Full Welded Ball Valve delivers excellent performance in high-pressure, high-cycle, and outdoor applications.
We provide professional OEM and customization services to meet different project requirements, including customized valve dimensions, materials, pressure ratings, welding standards, connection designs, coating systems, sealing solutions, and actuator configurations.
All valves are manufactured under strict quality management systems and comply with international valve industry standards. We provide complete certifications, including ISO 9001, API, CE, ASME, API 6D, ISO 14313, and other applicable industry certifications, ensuring reliable quality and global application compliance.
