Mehul PTFE Lined Pipe is one of the leading producers of PTFE, FEP, and PFA Lined Check Valves in Ahmedabad, India. PTFE Check Valves are one of the valves utilized for controlling the flow of fluids in a piping system, whereby liquid can flow in one direction with automatic backflow prevention. Of the various varieties, the PTFE lined swing check valve boasts a swinging variety and internal PTFE synthetic polymer finish for increased hardness. Disc and ball check valves are the others, each utilizing a unique way of controlling the flow. PTFE lined ball valves actually come in an inner PTFE coating which decreases erosion and corrosion caused by hostile fluids. This lining protection ensures that the inner material of the valve is not influenced by internal environmental conditions, enhancing longevity and performance.

What is PTFE Lined Check Valve?

A PTFE Lined Check Valve is a check valve employed to prevent backflow in piping systems and permit fluid flow in one direction only. The valve interior is lined with PTFE (Polytetrafluoroethylene), a resistant synthetic polymer against corrosion, that protects against severe chemicals and hard fluids. Swing, ball and disc check valves are some general types, where each of these has a difference in flow controlling mechanism. PTFE lining enhances strength, maintains the integrity of the core material of the valve and allows safe operation under challenging industrial requirements.
