Swing-type fluorine-lined check valve, H44F46, Fluorine-lined check valve, Swing-type check valve, Check valve

To ensure that the pipeline medium does not come into direct contact with the valve body material, the internal components such as the valve body, valve cover, valve disc, etc. in this product are all designed as lined components; the valve seat uses an integral polymer as the sealing material, which has excellent sealing performance within a wide range of temperature and pressure; the valve material selection is extensive and the specifications are complete. It is an ideal valve for the transportation of pipelines in petroleum exploration, petrochemical, chemical, crude oil and natural gas, etc. The valve stem is designed as a segmented type and is connected by positioning clamps, which is conducive to the control of the valve opening and maintenance.

The FEP (F46) and PCTFE (F3) fluorine-lined swing-check valves are suitable for use in various concentrations of aqua regia, sulfuric acid, hydrochloric acid, hydrofluoric acid, and various organic acids, strong acids, and strong oxidants within the temperature range of -50℃ to 150℃. The FEP fluorine-lined swing-check valves are also applicable for use in pipelines carrying various concentrations of strong alkaline organic solvents as well as other corrosive gases and liquid media. The FEP fluorine-lined swing-check valves are also applicable for use in pipelines carrying various concentrations of strong alkaline organic solvents as well as other corrosive gases and liquid media.
