Product Overview
The SMC LVA20A-02-C is a high-purity chemical valve engineered by SMC Corporation for precise, contamination-free control of aggressive and ultra-pure fluid media in semiconductor, pharmaceutical, and analytical instrumentation systems. Operating on a direct-acting pneumatic principle, this valve utilizes a PTFE (polytetrafluoroethylene) wetted body and diaphragm isolation design to prevent media contact with metallic actuation components, ensuring chemical inertness and eliminating particle generation. With a 1/4″ port size and a compact, space-efficient footprint, the LVA20A-02-C serves as a critical flow-control component in high-purity chemical delivery lines, where leak-tight shutoff and minimal dead volume are essential for process integrity.
