Failures are the most common questions that plant personnel ask when it comes to issues on PTFE lined butterfly valves. We know how frustrating they are when you come across a problem like this, especially if PTFE lined butterfly valve is a newly purchased item and you’d expect the best from it.

A PTFE lined butterfly valve is a rotary valve that uses a disc as the closure member. The disc shaped closure member is rotated through 90 or there about to open or close the passage. The disc of PTFE lined butterfly valve closes against a ring seal to close off the flow.

A high-performance PTFE lined butterfly valve is a quarter-turn valve best suited for handling large amounts of liquids or gases. PTFE lined butterfly valves are easy to handle and are used in many flow control and throttling applications.

Pipeline medium are becoming much more complex in modern anti-corrosion pipeline. As such, valve requirements are getting complicated as well. Among all the anti-corrosive valves especially the traditional valves with special material like inconel alloy valves
