Diaphragm-Sealed Valve

Swagelok® Diaphragm-Sealed Valves

Diaphragm-sealed valves minimize entrapment areas and facilitate purging with a fully swept flow path to improve system efficiency while providing effective flow shutoff. A variety of sizes, materials, and configurations, including atomic layer deposition, thermal immersion, and springless, meet the system requirements of high-purity and ultrahigh-purity applications.
