High-purity PFA material, defining industry purity standards

Ultimate Purity Assurance:

RETZ high-purity PFA (Perfluoroalkoxy) diaphragm valves are made from high-purity PFA raw materials, undergoing strict purification processes with extremely low impurity content, meeting the stringent material purity requirements of high-precision industries such as semiconductors and pharmaceuticals. In semiconductor chip manufacturing, 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 media such as ultrapure water and high-purity chemical reagents remain uncontaminated, laying a solid foundation of purity for high-end manufacturing.

Excellent Chemical Stability:

PFA inherits the excellent chemical properties of polytetrafluoroethylene (PTFE), offering superior corrosion resistance and withstanding almost all chemical media. Whether it's aqua regia, hydrofluoric acid, or other highly corrosive substances, as well as various acid and alkali solutions, it is difficult to damage the material. In the pharmaceutical industry, where multiple chemical reagents are involved in production processes, using this valve ensures safe media transport, avoiding cross-contamination caused by material corrosion, and ensuring the safety and effectiveness of drug production.

Ultra-High Purity & Corrosion Resistance:
PFA Material: Perfluoroalkoxy resin (PFA) purity ≥99.99%, no metal ion leaching, meeting stringent standards such as SEMI and USP Class VI, suitable for corrosive media like ultrapure water, acids (e.g., hydrofluoric acid), alkalis, and organic solvents.
Zero Contamination: The valve body cavity is smooth and free of dead ends, avoiding fluid residue and cross-contamination, ideal for clean processes such as semiconductor wafer cleaning and biopharmaceuticals.
2. Excellent Sealing Performance
Diaphragm Design: Uses PFA/FFKM diaphragm, with strong elasticity and fatigue resistance, achieving 100% zero leakage, eliminating the risk of external leakage (especially for toxic or high-value fluids).
No Metal Contact: The fluid only contacts PFA material, avoiding metal contamination, suitable for sensitive applications such as the optoelectronics industry and lithium battery electrolytes.
3. Long Life & Low Maintenance
Aging Resistance: PFA has a wide temperature resistance range (-196°C to +150°C), resistant to UV and chemical degradation, with a service life far exceeding that of PVC and PP valves.
Lubrication-Free Structure: No need for regular lubrication, reducing maintenance costs, suitable for automated production lines.

Precision Structural Design for Efficient and Accurate Control

Low Dead Volume Design:

RETZ imported high-purity PFA diaphragm valves adopt a low dead volume design, minimizing the space for residual media inside the valve. In scenarios with extremely high requirements for micro-sample handling, such as laboratories and biopharmaceuticals, the low dead volume design effectively avoids sample residue and cross-contamination, ensuring accuracy and consistency in each experiment or production process. Additionally, this design reduces media waste, improves production efficiency, and lowers production costs.

Reliable Sealing Performance, Eliminating Leakage

Tightly Fitted Diaphragm Seal:

Dual Sealing Assurance: Some high-end models of imported high-purity PFA diaphragm valves are equipped with a dual sealing structure, adding an auxiliary sealing device on top of the diaphragm seal. This dual sealing design further enhances the valve's sealing reliability, effectively preventing media leakage even under extreme conditions such as high pressure and high temperature, providing more reliable safety assurance for industrial production.

Application Scenarios Highlighting Selling Points
Semiconductors: "Ensures UPW (Ultrapure Water) system TOC <1ppb, helping to improve 5nm chip yield."
Pharmaceuticals: "Aseptic-grade design complies with FDA 21 CFR177.1550, meeting vaccine production ASME BPE requirements."
Chemicals: "Resists 98% concentrated sulfuric acid, 30% hydrogen peroxide, replacing Hastelloy valves with a 40% cost reduction."

Conclusion:
As the core sealing component of the valve, the diaphragm tightly fits the valve seat in the closed state, forming a reliable sealing surface. Imported high-purity PFA diaphragm valves use advanced manufacturing processes to ensure the sealing precision between the diaphragm and the valve seat, effectively preventing media leakage. When transporting hazardous media such as toxic, harmful, flammable, or explosive substances, this reliable sealing performance ensures production safety, avoiding accidents and environmental pollution caused by leakage.
