1 gas ball valve is a type of valve that uses a ball to regulate the flow of fluids through a pipeline. The ball is fixed in place and does not move, and the valve operates by rotating the stem, which in turn rotates the ball. This design is simple and reliable, and fixed ball valves are commonly used in a variety of industries. Fixed ball valves are available in a range of sizes, materials, and pressure ratings to suit different applications.
