Swagelok 6LVV-DPB111P-CS-47728 Diaphragm Valve

Swagelok 6LVV-DPB111P-CS-47728 is an ultrahigh-purity diaphragm-sealed valve from Swagelok’s DP Series, engineered for clean-gas distribution in semiconductor processing, analytical instrumentation, and other high-purity gas systems. The 6LVV designation identifies a 316L VIM/VAR stainless steel body, aligning with Swagelok’s ultrahigh-purity platform. DP Series valves use a springless diaphragm design intended for high cycle life and minimizing gas entrapment, making them well suited for precise shutoff in demanding environments. This variant is part of the DP family’s high-purity lineup and supports operating pressures up to 300 psig (20.6 bar). Typical applications include gas distribution manifolds in semiconductor fabrication, chemical processing lines, and lab-scale purge and pressurize sequences where ultra-clean materials and compatibility are essential. The exact model is reported in distributor listings as discontinued, so customers planning new systems should verify current Swagelok offerings for suitable replacements or upgrades.
