Product Overview
The FUJIKIN 796-029684-321 REV. A / 1001360 is an ultra-pure diaphragm valve engineered by Fujikin, a global leader in precision fluid control technology. Operating on a pneumatically actuated diaphragm principle, this valve isolates the working fluid from all internal actuation components, eliminating dead volume, particle generation, and contamination pathways. It is specifically designed for high-purity gas and chemical delivery systems where molecular-level cleanliness and leak-tight shutoff are mandatory. The valve serves as a critical control element in semiconductor fabrication, pharmaceutical processing, and advanced analytical instrumentation, providing precise on/off flow control with exceptional cycle life.

Engineering Features & Advantages
- Precision Performance: The diaphragm isolation design ensures zero dead volume and eliminates entrapment zones, providing consistent, repeatable flow control critical for ultra-pure media handling. The pneumatic actuator delivers fast, uniform response with minimal hysteresis.
- Industrial Reliability: Built for continuous operation under severe industrial conditions, the valve’s robust construction and high-cycle diaphragm withstand aggressive chemicals and high-purity gases without degradation or particle shedding.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original OEM standards, ensuring drop-in replacement for Fujikin 796 series installations without modification to existing manifolds or pneumatic supply lines.
- Contamination-Free Operation: All wetted surfaces are electropolished and passivated to minimize surface roughness and adsorption, meeting stringent semiconductor and pharmaceutical cleanliness requirements.
- Compact Modular Design: Space-efficient body allows high-density integration into gas sticks, valve manifold boxes (VMBs), and process gas panels.
