Product details

Fluorine lined vertical check valve is a special type of valve mainly used to prevent reverse flow of media in pipelines. Its working principle is to use the flow power of the medium itself to automatically open and close the valve disc to prevent the medium from flowing back, so it is also known as a check valve or one-way valve. The main feature of the fluorine lined vertical check valve is that the surface of its valve body cavity is covered with a layer of fluoroplastic, which gives the valve excellent corrosion resistance and is suitable for environments with various corrosive media.

Texture of material

The fluorine lining process uses corrosion-resistant materials such as PTFE (F4), FEP (F46), PCTFE (F3), etc. for the contact surfaces inside the valve, and is combined with stainless steel or cast steel structure to improve the durability and reliability of the valve in harsh environments.

Types and characteristics

Check valves can be divided into silencing check valve, ball check valve, butterfly check valve, but they can also be divided into vertical check valve and swing check valve according to other types. Fluorine lined vertical check valves can be divided into various types such as lifting type and swing type according to their structure and working principle. The valve disc of the lift check valve moves up and down along the axis of the valve body channel, suitable for installation in vertical pipelines; The valve disc of the swing check valve rotates around the axis outside the valve seat and is suitable for larger diameter horizontal pipelines. Each type of valve has its unique advantages and application scenarios, and users can choose the appropriate valve type based on specific working conditions and requirements.

Fluorine lined vertical check valves play a crucial role in many industries due to their excellent corrosion resistance and reliable safety performance. Finally, the combination of a check valve and a globe valve can serve as a safety and isolation device.
