The PTFE Solenoid Valve is an automated basic component that uses an electric current to open or close the fluid flow path. Its core feature is that all wetted parts are constructed from high-quality Polytetrafluoroethylene (PTFE) material. This design makes it an ideal solution for handling highly corrosive, high-purity, or viscous fluids, widely used in industries such as chemical, pharmaceutical, food and beverage, and water treatment.
Exceptional Corrosion Resistance
PTFE material can resist almost all strong acids, strong alkalis, strong oxidizing agents, and organic solvents, ensuring a long service life and high reliability.
High Purity & Low Contamination
The valve body features a smooth, seamless interior with no leaching of metal ions. It is perfectly suited for applications requiring extremely high fluid purity, such as semiconductor, biopharmaceutical, and food processing.
Excellent Anti-Stick Properties
PTFE has a very low surface tension, preventing media adhesion. It effectively handles viscous liquids, slurries, or crystallizing fluids, preventing valve clogging.
Broad Temperature Compatibility
Capable of stable operation within a medium temperature range of -20°C to +150°C, meeting various operational requirements.
Reliable Sealing Performance
Utilizes a PTFE diaphragm or piston sealing structure, offering an extremely low leakage rate to ensure operational and environmental safety.
Various Actuation & Power Options
Available in different functions such as normally closed and normally open. Supports multiple voltage specifications including AC (Alternating Current) and DC (Direct Current), facilitating easy integration into diverse automation control systems.
Chemical Industry: Transferring corrosive chemicals like hydrochloric acid, sulfuric acid, sodium hydroxide, and solvents.
Pharmaceutical & Bioengineering: Handling the transfer of purified water, Water for Injection (WFI), medicinal solutions, and culture media in sterile processes.
