HK55-F-C Cast Iron Pneumatic Actuator Fluorine Ball Valve

The series of corrosion-resistant fluorine lined ball valve is designed for the opening and closing control of various strong corrosive medium pipelines. Flange type fluorine lined ball valve cavity and ball are lined with corrosion-resistant and aging resistant polypropylene by high-pressure injection molding process, so it has reliable corrosion resistance and sealing performance. It is widely used in chemical, petroleum, metallurgy, medicine and other industrial sectors to adjust or cut off the strong corrosive medium such as acid and alkali in the production process, and has the most obvious effect in the control of water treatment process. It is one of the most ideal choice of anticorrosive valve equipment at present

  • Model: HK55-F-C
  • Size Range: 1/2" to 2"
  • Pressure Range: 1.6MPa to 6.4MPa
