The Pneumatic Fluorinated Lined Globe Valve (J641F46) features a compact structure, high strength, and superior corrosion resistance. Specifically designed for controlling corrosive media, its internal cavity is fully lined with corrosion-resistant fluorinated material. It is suitable for pipelines carrying corrosive gases, liquids, and solutions of various concentrations at temperatures ranging from -10°C to 150°C. The valve seat employs an integral polymer sealing material, delivering excellent sealing performance across a broad range of temperatures and pressures. As a valve where the closing member (disc) is actuated by the stem to move vertically along the seat's central axis, it primarily serves to connect or disconnect media flow within pipelines. However, it is not suitable for throttling applications.
