What is a lined butterfly valve?

If you are in search of a valve to regulate or prevent the flow of fluid look no ahead. Lined Butterfly Valves are the best options for you.

These valves normally isolate or regulate the flow of fluid. The disc that sits at the centre of the valve is used as a closing mechanism. A handle connects the disk and the top of the valve. It passes through a shaft. The disc in the PTFE lined butterfly valve induces the pressure drop. Since it is light in weight it requires less support and can be shut off quickly.
