PFA Valves
Precision PFA Valves for Extreme Corrosion & Ultra-High Purity Applications
CYLEXPRO is a leading manufacturer of high-performance fluoropolymer valves, specializing in PFA (Perfluoroalkoxy) Valves and PTFE Valves. Our products are engineered to handle the most aggressive chemicals and meet the stringent purity requirements of critical industries worldwide. From semiconductor fabrication to biopharmaceutical processing, our valves ensure unmatched reliability, safety, and contamination-free fluid control.
Why Choose Our PFA Valves?
Superior Chemical Resistance: Manufactured from virgin PFA material, our valves withstand virtually all aggressive media, including concentrated acids, bases, solvents, and oxidizers at elevated temperatures.
Ultra-High Purity & Low Contamination: The inert nature of PFA ensures zero metallic ion contamination, making our valves ideal for UPW (Ultra-Pure Water), CMP, and etching processes in semiconductor manufacturing, as well as WFI (Water for Injection) systems in pharma.
Exceptional Thermal Stability: Perform reliably in a wide temperature range from -196°C to 260°C (-320°F to 500°F), ensuring process integrity in both cryogenic and high-temperature environments.
Comprehensive Compliance: Our sanitary and diaphragm valves are designed and finished to meet ASME BPE standards, with excellent surface finish (Ra < 0.4 µm) and full documentation support.
Our PFA Valve Product Range
We offer a complete portfolio of actuation and manual solutions to fit your specific system design:
PFA Diaphragm Valves: The industry standard for high-purity chemical delivery systems (CDS). Available in pneumatic actuated and manual handwheel versions.
PFA Ball Valves: Provide quick shut-off with minimal torque. Feature PFA-lined bodies or full PFA construction.
PFA Needle Valves: Allow for precise flow control in analytical and dosing applications.
PFA Check Valves: Prevent backflow and protect critical process equipment.
Trusted by Leaders in Critical Industries
