Product Overview
The FUJIKIN 766-077822-501 REVA / AK00X5D00 is an ultra-pure diaphragm valve engineered by Fujikin, a global leader in precision fluid control technology for semiconductor, pharmaceutical, and high-purity process industries. This valve utilizes a flexible diaphragm as the sole moving wetted component, isolating the process media from the actuator and bonnet assembly to eliminate contamination pathways and prevent dead-volume entrapment. The AK00X5D00 designation reflects Fujikin’s advanced air-operated diaphragm valve platform, designed for leak-tight shutoff and superior particle performance in critical high-purity gas and liquid delivery systems. With its REVA revision, this model incorporates the latest engineering refinements for enhanced cycle life and sealing integrity, making it an essential component in ultrapure fluid handling circuits where molecular-level cleanliness and zero-leak performance are mandatory.
