DOT 407 Magnetic Vacuum Breaker
The Magnetic Vacuum Breaker is a valve designed to limit negative pressure (vacuum)
in a typical tank trailer. A permanent magnetic force controls the movement of the valve
poppet to open on demand at 4” Hg or greater. All working parts are kept away from the
airflow paths, which promotes easy cleaning and hassle-free repairs.
