Application Of Stainless Steel Ball Valves


  • Stainless steel ball valves are mainly used in petrochemical industry, such as ethylene cracking device, polyethylene device and polypropylene device in ethylene production, PTA device (pure terephthalic acid), polyester device and polyester spinning device in chemical fiber production.

  • 304 and 304L ball valves are suitable for transportation in weak acid-base medium with less corrosion, such as nitric acid, fertilizer, benzene, oxygen, etc.

  • 316 and 316L ball valves are mainly used for medium transportation of strong acids and bases, such as acetic acid, hydrochloric acid, sulfuric acid, etc.
