Swagelok® Gas Cylinder Changeover Regulators

KCM series regulators auto-switch gas sources, ensuring continuous flow and reducing downtime.

Get Help Selecting Regulators

Swagelok's KCM series gas cylinder changeover regulators automatically switch between two gas sources to maintain continuous gas flow in critical industrial applications, reducing downtime and labor costs. Allowing reliable gas distribution with reduced oversight, KCM series changeover regulators are designed to require minimal maintenance. Convoluted, non-perforated diaphragms within the KCM series regulators provide durability and enhanced pressure response.
