Vacuum regulating valves
How it works
Vacuum regulating valves protect components against negative pressure. They are closed in the idle state. If the internal pressure of the components decreases by more than the set differential pressure in relation to the atmospheric pressure, the valve opens. The component is ventilated until the set differential pressure has been reached again. Vacuum regulating valves continue to be closed when the internal pressure of a component rises above the ambient atmospheric pressure and thus do not protect against overpressure.
