Among the various types, the PTFE lined swing check valve has a swinging type and an inner PTFE synthetic polymer coating for extra longevity. Disc and ball check valves are the other two types, with both types having a dissimilar process of controlling the flow. PTFE lined ball valves, in reality, comprise an inner PTFE coating minimizing erosion and corrosion caused by aggressive fluids. This lining provides assurance that the material inside the valve is not impaired by environmental interior conditions, enhancing performance and life.

What is PTFE Lined Check Valve?

A PTFE Lined Check Valve is a check valve applied in preventing backflow in piping systems and allowing for fluid to travel in a one-way direction only. The valve interior is lined with PTFE (Polytetrafluoroethylene), a corrosion-resistant man-made polymer that protects against harsh chemicals and aggressive fluids. Swing, ball and disc check valves are typical forms, each with varying flow control method. The lining of PTFE enhances strength, maintains integrity of the valve’s core material and offers safe operation under severe industrial use.
