Raise the bar using Vacuum Breaker Valves

Vacuum breaker and air valves are useful tools in the industry for protecting pipelines against vacuum or near vacuum conditions. High points in the pipe can be susceptible to these low-pressure conditions during surge events, as pressure waves moving through the system cause a sudden pressure upsurge or downsurge.

AFT Impulse can help engineers to identify if vacuum conditions will be present in their system and help to properly size vacuum breaker and gas release valves to protect the pipeline when these events occur. Here are some considerations to keep in mind when modeling these type of valves to best represent their complex behavior.
