PFA Needle Valve
The NV-01 Series Ultrapure PFA Needle Valve is specially developed to handle high-purity corrosive chemical liquids and gases. The design uses an injection molded high-purity PFA valve body and stem as the only wetted parts. The stem sealing area is precision machined to ensure a smooth and consistent turning feel. The PTFE ferrule ensures a reliable seal between the stem and the body. The specially designed PFA stem stop prevents the stem from loosening from the body during use.
CYLEX supports small-batch customization, offers discounts for large quantities, fast delivery, and provides guaranteed after-sales service.

CYLEX PFA Needle Valve: The Ultimate Solution for Critical Flow Control
In industries where purity and corrosion resistance are non-negotiable, the CYLEX PFA Needle Valve stands out. Manufactured with precision from high-grade PFA (Perfluoroalkoxy), this valve is your trusted partner for managing ultra-pure, aggressive, and sensitive fluids with absolute precision and safety.
Why Choose CYLEX PFA Needle Valves?
● Superior Material Performance: PFA offers exceptional resistance to nearly all chemicals, including strong acids, bases, oxidizers, and organic solvents, ensuring long-term integrity and performance.
● Guaranteed Fluid Purity: With ultra-low extractables and leachables, our valves prevent contamination in high-purity applications, making them ideal for semiconductor and pharmaceutical manufacturing.
● Precise Metering & Shut-Off: The fine-pitch thread and needle-point stem allow for multi-turn, micro-adjustment of flow rates, providing excellent control from a trickle to a full shut-off.
● Robust & Leak-Free Design: Engineered for durability and a tight seal, even after repeated cycles. Available with various sealing options (e.g., Viton, EPDM, Kalrez) to match your specific fluid compatibility needs.
● Versatile Connections: Designed to integrate seamlessly into your system with standard PFA flanged, threaded, or welded connections.
