Gas cylinder changeover regulators switch automatically between two gas sources, easing the burden and downtime associated with manual changeovers.

Swagelok® Gas Cylinder Changeover Regulators is a two-stage gas delivery system that ensures continuous flow of gases in critical applications. When one supply drops below the changeover pressure, the selector regulator automatically switches the gas feed from the depleted supply to an alternate supply. The automatic operation eliminates costly system downtime and maintenance expense of continuously monitoring the gas supply.
