Gas fixed ball valve
The Gas Fixed Ball Valve is a high-performance fixed ball valve specially designed for gas transmission, distribution, and industrial gas control systems. It adopts a trunnion-mounted fixed ball structure, providing excellent stability, reliable sealing, and safe operation under high-pressure and large-diameter pipeline conditions.
Unlike floating ball valves, the fixed ball design uses upper and lower stem support to reduce operating torque and improve service life, making it suitable for high-pressure gas applications and frequent operation requirements.
The valve is manufactured with advanced machining technology and strict quality control to ensure superior sealing performance, corrosion resistance, and long-term reliability. It is widely used in natural gas pipelines, LNG systems, petrochemical plants, and energy industries.
