3” ANSI Flange DOT 407 GEILINER ® Magnetic Vacuum Breaker

FUNCTION
This Teflon® lined, ultra low profile Magnetic Vacuum
Breaker is a valve designed to limit a 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. This lined vacuum breaker is
designed to protect against aggressive ladings that normally
would chemically attack stainless steel. All wetted surfaces
are lined with a 1/8” thick Teflon® liner. The valve seat seals
on a Tef-O-Sil encapsulated silicone O-Ring. This O-Ring
provides complete chemical resistance and a bubble-tight
seal. All working parts are kept away from the airflow paths,
which promotes easy cleaning and hassle-free repairs.
