Z TORK Automation Co. is a leading manufacturer, supplier and exporter of Lined Diaphragm Valve in Ahmedabad, Gujarat, India. Lined Diaphragm Valve is a type of control or shut-off valve that uses a flexible diaphragm to regulate the flow of corrosive or abrasive fluids. In this valve, the body is internally lined with chemically resistant materials such as PTFE, PFA, FEP, glass, or rubber to protect the valve from aggressive media. The diaphragm itself is also made of an elastomer or fluoropolymer and acts as the isolating element between the fluid and the valve’s moving parts.
