Difference between fluorine lined check valve and rubber lined check valve

Among various types of valves, check valve There are various types of products, but there are also many products with different materials. For example, the hard and soft seals of check valves, such as those made of steel alloy or copper alloy, are considered hard seals, while materials like plastic or plastic belong to soft seals. Today, let's take a look at the difference between fluorine lined check valves and rubber lined check valves:
Fluorine lined check valve is a corrosion-resistant valve, which is embedded in the inner wall of the valve by processing or molding polytetrafluoroethylene resin, and embedded in the inner lining or surface of the pipeline in the same way, with strong anti-corrosion performance.
Rubber lined check valve, which is used for non corrosive or generally corrosive media. The valve body cavity is not embedded with various rubbers and is used in fluid pipelines at different temperatures.
Overall, fluorine lined check valves have higher anti-corrosion performance and are suitable for use in pipelines with severe corrosion. Rubber lined check valves are a commonly used valve with relatively higher cost-effectiveness. It is recommended that consumers choose the appropriate valve according to their own needs.
