PFA Lined Check Valve


A check valve, also known as a non-return valve or one-way valve, is a mechanical device used to control the flow of fluids or gases in a single direction. Our PFA lined check valves are separated into spring checked type and ball valve type, offering excellent protection against chemical corrosion.

BUENO's PFA check valves are expertly crafted using Perfluoroalkoxy material with FDA certifications, ensuring their safety for use in various industries including pharmaceutical, biochemical, semiconductor, and optoelectronic manufacturing industries. Our products are water-free and oil-free, ensuring high purity with minimal oil content. The low friction of PFA enables smooth operation with low torque. Suitable for highly corrosive acids, interactions between acids and alkalis in fluid transportation systems, and processes involving organic compound precipitation and metal ion leaching in semiconductor and pharmaceutical manufacturing.

Our products are designed specifically for applications with highly corrosive media.
