PFA/PTFE Lined Control Valve

ALIS Valves offers PFA/PTFE Lined Control Valves for industrial applications that require precise flow regulation and reliable resistance to corrosive chemicals. These valves feature an internal lining made from PFA (Perfluoroalkoxy Alkane) or PTFE (Polytetrafluoroethylene), providing a chemically resistant barrier between the process media and the valve body. The control mechanism regulates the flow passage to help maintain the required flow rate and support stable process conditions. Depending on the valve design, these valves can be equipped with pneumatic, electric or other compatible actuation systems for automated or manual control. The lining material and internal components are selected according to the chemical properties of the media, operating temperature, pressure requirements and the control performance needed for the application.

PFA/PTFE Lined Control Valves are suitable for chemical processing plants, pharmaceutical manufacturing, acid and alkali handling systems, specialty chemical production, water treatment facilities and other industrial processes involving corrosive fluids. They can be specified for compatible acids, alkalis and chemical solutions within the operating limits of the selected lining and valve construction. Important selection factors include chemical compatibility, operating pressure, temperature range, flow coefficient (Cv or Kv), differential pressure, valve size, lining material, seat and sealing design, actuator requirements and required flow characteristics. PFA and PTFE have different mechanical and temperature performance characteristics, so the appropriate material should be selected based on the actual process conditions. Choosing the correct valve configuration helps support accurate flow control, corrosion protection and reliable service in demanding chemical applications.
