Fluorine-lined Gate Valve Product Introduction:
The fluorine-lined gate valve is divided into: straight-through fluorine-lined gate valve, direct-flow fluorine-lined gate valve, and angle fluorine-lined gate valve. It has advantages such as compact structure, flexible opening and closing, strong corrosion resistance, and short stroke (generally 1/4 of the nominal diameter). It is widely used in pipeline systems in petroleum and chemical industries for medium cutoff. However, it is emphasized that the fluorine-lined gate valve is strictly prohibited from being used for flow regulation to avoid erosion of the sealing surface caused by high-speed medium flow at the throttling port.
Fluorine-lined Gate Valve Application Range:
The fluorine-lined gate valve is suitable for various concentrations of aqua regia, hydrofluoric acid, and various organic acids, strong acids, and strong oxidants at temperatures of -50℃ to 150℃. FEP is also suitable for pipelines carrying various concentrations of strong alkaline organic solvents, as well as other corrosive gases and liquid media.
Fluorine-lined Gate Valve Structural Features:
1. Plastic Lining J41 Type Straight-through, J45 Type Direct-flow, J44 Type Angle Gate Valve, with advantages such as compact structure, flexible opening and closing, strong corrosion resistance, and short stroke (generally 1/4 of the nominal diameter). It is widely used in pipeline systems in petroleum and chemical industries for medium cutoff. However, the plastic-lined gate valve is strictly prohibited from being used for flow regulation to avoid erosion of the sealing surface caused by high-speed medium flow at the throttling port.
2. The valve disc and valve stem are designed as an integrated structure to prevent the possibility of internal components being ejected from the valve body due to pipeline pressure fluctuations, ensuring a compact structure and safe use.
