Swagelok H22-BN3673-2C Normally Closed Valve

Swagelok H22-BN3673-2C is a Hastelloy normally closed valve from Swagelok, configured with 1/4 in. female VCR end connections. This valve belongs to Swagelok’s H-series high-purity, bellows-sealed valve family, designed for precise shutoff in demanding chemical and gas-delivery systems. The Hastelloy construction provides robust corrosion resistance in aggressive environments, making it suitable for chemical processing, semiconductor manufacturing, and other high-purity applications where leak-tight performance matters. The NC designation indicates the valve defaults to a closed state and requires actuation to open, helping contain hazardous or costly process streams when power or control signals are absent. The VCR end connections offer reliable, leak-tight seals compatible with Swagelok VCR fittings in cleanroom and critical-service pipelines.
