Z TORK Automation Co. is a leading manufacturer, supplier and exporter of Lined Control Valve in Ahmedabad, Gujarat, India. Lined Control Valve is a type of control valve whose internal surfaces are lined with corrosion-resistant materials, such as PTFE (Teflon), PFA, FEP, PVDF, or rubber, to handle aggressive, corrosive, or abrasive media. The valve body is typically made from metal (e.g., cast iron or stainless steel) for strength, but the lining isolates the body material from contact with the process fluid.
