The Worm Gear Fully Welded Ball Valve is a heavy-duty valve designed for large-diameter or high-pressure pipelines, integrating a worm gear actuator with a fully welded ball valve body. The fully welded construction ensures maximum structural integrity and zero external leakage, while the worm gear mechanism provides reliable torque amplification, allowing operators to smoothly and precisely open or close large valves with minimal effort. Combining high sealing performance, robust strength, and operational ease, this valve is a critical component for reliable shut-off control in large-diameter pipelines across city gas, district heating, petroleum, and chemical industries.
