Application of Stainless Steel Flanged Ball Valves
- Stainless steel hand ball valve is mainly used in the 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 stainless steel ball check valve are suitable for transportation in weak acid-base medium with less corrosion, such as nitric acid, fertilizer, benzene, oxygen, etc.
- 316 and 316L hand operated valve is mainly used for medium transportation of strong acids and bases, such as acetic acid, hydrochloric acid, sulfuric acid, etc.
