Ultra-High Pure Diaphragm and Bellows Valves are engineered to meet the demanding requirements of semiconductor, pharmaceutical, solar, and specialty gas industries. All products are sourced exclusively from our trusted partner, TK-Fujikin, ensuring consistent quality, reliability, and global manufacturing standards.
These valves are designed to provide superior sealing performance, low particle generation, and maximum contamination control in ultra-clean gas delivery systems.
Diaphragm valves offer minimal dead space, excellent moisture displacement, and smooth flow paths, making them ideal for high-purity process applications. Bellows valves feature a robust metal bellows construction that ensures complete isolation between the process media and the external environment, providing zero external leakage for hazardous and corrosive gases.
Manufactured using high-grade stainless steel and advanced surface finishing processes, these valves are precision cleaned, helium leak tested, and packaged in cleanroom environments. With multiple actuation options and high reliability, Ultra High Purity Valves deliver consistent performance, safety, and durability in critical operating conditions.
