A SecoLok changeover gas manifold typically has two inlet ports—one for each gas source—and one outlet port connected to the downstream gas system. A valve controls which gas source is supplying gas to the outlet.
To switch sources, the valve is turned to the desired inlet port. This closes the previous gas source and opens the new one, with no interruption to the gas flow during changeover.
SecoLok gas panels are used in a wide range of industries including food and beverage, pharmaceutical, and chemical sectors. Common applications include:
