Fully Welded Trunnion Ball Valve

Product details

Because the valve body material is the same as the pipe material, there will be no uneven stress, but also avoid potential leakage path to the external environment, to ensure the reliable protection of the entire system. The robust binaural construction and two independent seats with bi-directional seals ensure maximum sealing and reliability under high pressure and temperature conditions in all critical isolation services. Unique features provide advanced technical solutions for urban gas output pipelines, main lines and feeder supply pipelines. The material selection is fully customizable to meet the customer's project specifications.
