Emre PTFE Lining is a leading Turkish, Istanbul manufacturer of PTFE, FEP, and PFA Lined Check Valves. PTFE Check Valves are among the valve types utilized for fluid flow regulation in a piping system, whereby liquid can only flow in one direction with automatic backflow prevention. Of the various types, the PTFE lined swing check valve comes with a swinging type and an internal PTFE synthetic polymer coating for increased longevity. Disc and ball check valves are the other two, and each of them has a unique flow control mechanism. PTFE coated ball valves, in fact, consist of a PTFE coating on the inside that assists in reducing erosion and corrosion caused by aggressive fluids. The protective coating prevents the inner material of the valve from being affected by inner environmental conditions, improving performance and lifespan.

What is PTFE Lined Check Valve?

A PTFE Lined Check Valve is a check valve applied to prevent backflow in piping systems and permit fluid flow in one direction only. The valve interior is lined with PTFE (Polytetrafluoroethylene), a corrosion-proof synthetic polymer that protects against aggressive chemicals and hostile fluids. Swing, ball and disc check valves are typical varieties, each with a different mechanism of flow control. The PTFE lining enhances strength, maintains integrity of valve’s core material and ensures safe operation in rigorous industrial applications.
