The vacuum breakers VV 34
are valves which allow air to be aspirated once a set vacuum or pressure difference to atmosphere is reached.
These valves are installed on pipelines, vessels, machines and equipment and are used, for instance, for venting tanks, limiting the vacuum in vacuum systems and protecting steam installations.
The VV 34 vacuum breakers have a tension spring and a spring cap complete with scale for setting the breaking pressure.
