PTFE Lined Check Valve

Peter PTFE Lined Pipe is a leading producer of PTFE, FEP, and PFA Lined Check Valves in Africa. PTFE Check Valves are among the valves utilized to manage fluid flow through a piping system, whereby liquid can flow in one direction only with automatic backflow prevention. Among the various types, the PTFE lined swing check valve has a swinging type and an internal PTFE synthetic polymer coating for extra durability. Disc and ball check valves are the other types, with each using a different mechanism of flow control. PTFE lined ball valves, in fact, comprise an internal PTFE coating that minimizes erosion and corrosion caused by aggressive fluids. This lining prevents inner material of valve from the impacts of environmental inner conditions, ensuring longer longevity and better performance.

What is PTFE Lined Check Valve?

PTFE Lined Check Valve is a check valve for backflow prevention in piping and one-way passage in piping systems. It has PTFE-lined (Polytetrafluoroethylene) inner surface, which is an aggressive chemical corrosion-resistant synthetic polymer that is shielded from aggressive chemicals and harsh fluids.Swing, disc and ball check valves are general types, and each has a different flow control mechanism. Strength is enhanced and the integrity of the core material of the valve is maintained while safe operation under demanding industrial environments is ensured by the PTFE lining.

What is a PTFE Lined Check Valve?

A PTFE Lined Check Valve is a valve that prevents reverse flow in pipes, featuring a lining made of PTFE to enhance corrosion resistance and chemical compatibility.

How can I maintain a PTFE lined check valve?

To maintain optimal performance, regularly inspect the valve for signs of wear, clean it thoroughly, and ensure the PTFE lining remains intact and properly sealed to extend its service life.

What materials are used in PTFE Lined Check Valves?

The valve body is typically made from carbon steel or stainless steel, and it is lined with PTFE (Polytetrafluoroethylene) for superior chemical resistance and durability.

How does a PTFE lined check valve function?

A PTFE lined check valve permits fluid to flow in one direction and automatically closes to prevent backflow when the flow stops, with the PTFE lining minimizing wear and chemical damage.

What industries use PTFE Lined Check Valves?

PTFE Lined Check Valves are widely used in industries like chemicals, pharmaceuticals, oil and gas, food processing, and water treatment due to their chemical resistance and reliability.
