The vacuum breaker VV 34 ATEX H2
are valves which allow air to be aspirated once a set vacuum or pressure difference to atmosphere is reached. They are specially developed for hydrogen applications.
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 vacuum breaker has a tension spring and a spring cap complete with scale for setting the breaking pressure.
