The difference in material and usage between PTFE lined valves and rubber lined valves

    PTFE lined valve Valve products made of two different materials, namely rubber lined valves and rubber lined valves, are still widely used in the industrial and chemical fields today, and have a large demand for many enterprises. The materials used for PTFE lined valves and rubber lined valves both have outstanding anti-corrosion performance, so what are the differences between them? Below is a detailed introduction for everyone.
Let's take a look at PTFE lined valves first. PTFE lined valves are known as plastic, which is a corrosion-resistant material. Therefore, PTFE lined valves can work in various high-intensity corrosive environments such as sulfuric acid and hydrochloric acid with high concentrations. However, this type of valve is also greatly limited by temperature, as high temperatures can cause deformation of the PTFE lining material, which can lead to leakage of the medium and cause dangerous accidents. It is recommended to use it at a temperature between -50 degrees Celsius and 150 degrees Celsius.
Rubber lined valves are a type of valve widely used in the petrochemical industry and are highly favored by some engineering projects. This is because the rubber lined valve has a dual function of switching and regulating flow, which does not affect the flow rate of the medium during use. In addition, the surface of this valve chamber is covered with various rubber materials, which can adapt to different working environments.
In addition, these PTFE lined valves and rubber lined valves should be stored in a dry place during storage, avoiding direct sunlight and rain, as well as being close to fire sources to prevent deformation of the valve lining.
The above is the difference in materials and related uses between PTFE lined valves and rubber lined valves. We hope it can be helpful in distinguishing between these two types of valves.
