The company takes "committed to anti-corrosion, pioneering and innovative" as its core development concept, and introduces high-end equipment and manufacturing process upgrades from home and abroad.
High-performance manual fluorine-lined ball valve is designed, manufactured, inspected and tested in accordance with the provisions of GB/T12237 and factory standards. It is suitable for acid, alkali and salt corrosive media with temperatures ranging from -29°C to 180°C, and is determined by the maximum operating temperature of its lining material. It is mainly used to control the on-off of the pipeline system. It has the advantages of small fluid resistance, simple structure, reliable sealing, and rapid opening and closing. The products are widely used in many fields such as new energy, petroleum, chemical industry, dyeing, pesticide, acid and alkali production.
The fluorine-lined flange butterfly valve produced by our company is suitable for temperatures ranging from -29 degrees Celsius to 180 degrees Celsius, and is suitable for strong acids and alkalis. It is used as a start-stop device in the pipeline system and can ensure good sealing performance under working pressure. The lined butterfly valves launched by the company are divided into: clamp connection and flange connection according to the connection method. According to the main body material, it can be divided into carbon steel lined butterfly valve and stainless steel lined butterfly valve. Lining materials include: PTFE, FEP, PFA, etc. This type of valve can control a variety of drive devices such as manual, pneumatic, electric, and hydraulic to achieve remote control and automatic operation.
