Girard - Model DOT 407 - Ultra Low Profile Magnetic Vacuum Breaker Brochure

The new ultra low-profile Magnetic Vacuum Breaker is a valve designed to limit a negative pressure (vacuum) in a typical tank trailer. This model has a 3" NPS swivel connection and stands less than 4" when installed on a typical tank nozzle, making it easy to install under already existing overturn protection.
