Vacuum Relief Valve for Blower Systems

The Fuji VV8 vacuum relief valve protects blower installations by opening at a preset limit of 100 in wc. It installs directly on 2 in NPT female pipe threads and measures 6.25 in overall length.

Replaces Worn Relief Valves on Compatible Blowers

The valve matches manufacturer part numbers VFC800A-7W, VFC904A-7W, VFZ801A-5W and VFZ801A-7W. It is the correct replacement when the original relief component no longer holds its vacuum setting.

Holds Set Pressure During Continuous Operation

The preset vacuum limit remains stable while the blower runs under sustained load. The valve cycles open and closed as needed without drifting from the 100 in wc threshold.
