It is best to maintain the vacuum differential (pressure differential) by lowering the vacuum, which will be more reliable than a valve configuration.
Have an insight or suggestion?

I think maintain the vacuum pressure uniquely it's better lowering the vacuum. The more relevant configuration is helpful on working atmosphere. Thanks. http://www.mitechtechnology.com/
