Product Overview
The SMC LVR50-Z19N 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 advanced chemical processing systems. Operating as a pneumatically actuated process valve, it utilizes a direct-acting diaphragm or bellows-sealed mechanism to isolate the working fluid from the actuator and external environment, preventing particle generation and media cross-contamination. The LVR50-Z19N is specifically configured with a Z19N designation, indicating a high-purity wetted-path specification with PFA or PTFE body construction and a normally closed (N.C.) pneumatic actuation mode. This valve serves as a critical flow-control component in high-purity chemical delivery lines, where leak integrity, minimal dead volume, and chemical resistance are paramount.
