KCM Series Gas Cylinder Changeover Regulator
Brand: Swagelok CompanyThe KCM series 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 of the KCM series eliminates costly system downtime and maintenance expense of continuously monitoring the gas supply. The KCM series gas changeover uses Swagelok KPR Series General Purpose Regulator.
