SecoLok Changeover Gas Manifold
Description
A SecoLok changeover gas manifold typically has two inlet ports, one for each gas source. There is also an outlet port that is connected to the downstream gas system. A valve is used to control which gas source is currently supplying gas to the outlet port.
To change over to the other gas source, the valve is simply turned to the other inlet port. This closes the valve to the previous gas source and opens the valve to the new gas source. There is no interruption to the flow of gas during the changeover process.
Applications
SecoLok gas panels are used in a variety of applications in the food and beverage, pharmaceutical, and chemical industries. Some specific applications include:
- Nitrogen purging of food and beverage products
- Helium purging of pharmaceutical products
- Oxygen purging of chemical products
- CO2 purging of food and beverage products
