Changeover
(SCO)
Introduction
A Swagelok ® changeover (SCO) is a special type of primary gas control system, pre-engineered
for applications where the continuous supply of gas is critical. When one source is depleted below
a selected changeover pressure, the continuous gas delivery system automatically switches to a
back-up supply. The depleted source can then be changed, in-line, without downtime.
