Contact usThe overall structure of the American standard fixed welded ball valve adopts a fully welded process structure, which greatly improves the internal and external sealing of the valve. Due to the valve being made of pipe material or A105 forging, the valve body itself has achieved zero sand holes, and there will be no external leakage of the valve body. Widely used in underground pipelines of urban gas, centralized heating, natural gas transmission pipelines, pressure regulating stations, and other fields.
