625 Air inlet valve made of brass, weight-loaded
For the safeguarding of depressurized tanks and piping systems to prevent the occurrence of vacuum during discharge or cooling, vacuum protection is essential. These specialized valves, often referred to as 'sniffing valves,' automatically open when a vacuum is detected, allowing the release of air until the vacuum is alleviated.
Application:
During the emptying of tanks, it is crucial to have protection against vacuum formation in unpressurized containers and piping systems. These vacuum valves, also known as "sniffer valves," activate in response to negative pressure, allowing air passage until the negative pressure is resolved.
