The Difference Between The Materials And Uses Of Ptfe Lined Valves And Rubber Lined Valves

Lined Valve and rubber-lined valves, two different materials of valve products, are still widely used in the field of industrial chemical industry today, and there is a large demand for many companies. The materials used in PTFE-lined valves and rubber-lined valves have outstanding anti-corrosion properties, so what is the difference between them? Let's introduce them in detail.
Let's take a look at the PTFE-lined valve first. PTFE-lined valves are known as plastics, and plastic materials are a kind of material that is not afraid of corrosion. Therefore, PTFE-lined valves can work in various high-concentration sulfuric acid, hydrochloric acid and other high-intensity corrosive environments. However, this type of valve is also limited by temperature, because high temperature will cause the PTFE-lined material to deform, and deformation will cause medium leakage, thereby causing dangerous accidents. It is recommended to use the temperature between -50 degrees Celsius and 150 degrees Celsius.
Rubber-lined valves are a type of valve that is widely used in the petrochemical industry and are favored by some engineering projects. This is because the rubber-lined valve has the dual functions of switching and regulating flow, and it does not affect the flow of the medium while in use. In addition, the surface of the valve cavity is covered with various rubber materials, which can adapt to different working environments.
In addition, the PTFE-lined valves and rubber-lined valves should be stored in a dry place, away from the sun and rain, and near fire sources, so as to prevent the valve lining from deformation.
The above is the difference in the materials and related uses of PTFE-lined valves and rubber-lined valves. I hope it can help you in distinguishing these two valves.
