Vacuum breaker sanitary VBS17

The ADCAPure VBS17 is a series of sanitary vacuum breakers designed to automatically relieve or “break” an unwanted vacuum condition. Applications include venting and vacuum limiting in pipelines, reactors, heat exchangers, autoclaves, amongst others. These valves should not be used as vacuum control valves. 

The device is kept close by means of a spring-loaded valve and the pressure which acts on the underside of the plug. When pressure drops below the adjusted set pressure, unbalancing of forces causes the valve to open, allowing atmospheric air to enter the system. With raise in differential pressure results an increase in valve stroke and air flow. 

The units are available with an optional lift indicator to signal in case of opening, for monitoring or contamination detection purposes.
