measurements - How to regulate a vacuum pump .

The device you're looking for is called a vacuum regulator and sits between the vacuum source and the process. This page from Equilibar shows some examples and provides links that explain how they work.. You can also use a vacuum breaker, which operates more or less like a pressure relief valve, but a vacuum regulator will offer more precise control.
