WEEON's PFA lined valve types include ball valves, diaphragm valves, 3-way/4-way ball valves, and ball check valves.                                                                           WEEON PFA lined ball valves are more flexible, reliable & easy to operate with less torque value. The lining locked by grooves allow the valves to be used on high vacuum, pressure and temperature application without lining collapse, shrinkage and blowout.                Also, WEEON PFA lined ball valves are virtually unaffected by changes in processing operation or chemical concentration like chloride, sulfuric acid, mixed acid.                                                                                                   For detailed information on each product, please refer to the WEEON website.       Applied standard are as follows.
