The valve body is made of stainless steel, which possesses excellent acid-alkali resistance and anti-rust performance. It can effectively resist the erosion of water, steam, and weak corrosive media, avoiding issues such as easy rusting and damage.The sealing surface is treated with an integral lining of polytetrafluoroethylene (PTFE). Known as the "King of Plastics," PTFE features outstanding corrosion resistance and good wear resistance.The handle is equipped with a limiting device, which enables precise control of the opening degree (0-90°) to meet precision requirements.Thanks to its material advantages and stable performance, this valve is widely used in various industries including chemical engineering, pharmaceutical manufacturing, food and beverage, water treatment, electric power, and metallurgy. It can be used not only for on-off control of ordinary fluids but also for the transportation of corrosive media and clean media.
