The opening and closing component of the imported internal thread PFA pneumatic diaphragm valve and high-purity fluoroplastic diaphragm valve is a diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the valve cover and the driving components. The overall material is made of PFA components, and the diaphragm is made of PTFE material, providing excellent resistance to high-purity and highly corrosive chemicals.
High-purity PFA material, defining industry purity standards
Ultimate Purity Assurance:
RETZ high-purity PFA (perfluoroalkoxy) diaphragm valves use high-purity PFA raw materials, undergo strict purification processes, and have extremely low impurity content, meeting the stringent material purity requirements of high-precision industries such as semiconductors and pharmaceuticals. In the semiconductor chip manufacturing process, even trace amounts of metal ions or organic impurities can affect chip performance and yield. With its high-purity PFA material, this valve ensures that transported ultrapure water, high-purity chemical reagents, and other media remain uncontaminated, laying a solid foundation of purity for high-end manufacturing.
Outstanding Chemical Stability:
PFA inherits the excellent chemical properties of polytetrafluoroethylene (PTFE), offering superior corrosion resistance and the ability to withstand almost all chemical media. Whether it's strong corrosive substances like aqua regia or hydrofluoric acid, or various acid and alkali solutions, they are unlikely to cause damage. In the pharmaceutical industry, where multiple chemical reagents are involved in production processes, using this valve ensures safe media transport, avoids cross-contamination due to material corrosion, and guarantees the safety and effectiveness of drug production.
