What is PTFE Lined Diaphragm Valve?

A PTFE Lined Diaphragm Valve is a control valve of flow type built with an internal lining of PTFE (Polytetrafluoroethylene) for chemical and corrosion attack resistance. It follows the principle of a flexible diaphragm which travels in an upward or downward direction to open or close the passage of flow. Being used widely in pharmaceutical, food and beverages, biotechnology and semiconductor industries, the valve provides high purity and leak-tight operation. The PTFE lining further safeguards the valve body against aggressive media, prolonging life and ensuring pipeline system integrity.
