What Is The Difference Between Ptfe Lined Valves And Rubber Lined Valves?

In today's industrially developed era, with the development of some enterprises, there is a large demand for Lined Valve and rubber-lined valves. So both valves have outstanding anti-corrosion performance, what is the difference? Let's take a look at the differences between these two valves.
Let's take a look at the PTFE-lined valve first. The PTFE-lined valve is known as plastic, and plastic is a material that is not afraid of corrosion. Therefore, the PTFE-lined valve can work in various high-concentration sulfuric acid, hydrochloric acid, etc. High-intensity corrosion environments. However, this valve is greatly 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 used most 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 rubbers, which can adapt to different working environments.
In addition, these two 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 between PTFE lined valves and rubber lined valves. I hope it can help you distinguish between these two valves.
