Product identity

The Fuji VV6 is a blower relief valve calibrated to open at 86 in wc of vacuum. It serves technicians and maintenance crews who need automatic pressure protection on positive-displacement blowers.

Installation fit

The valve mounts directly to a 2 in female NPT inlet and has an overall length of 6.25 in. It replaces compatible units such as VFC600A-7W, VFZ601A-5W and VFZ601A-7W without requiring piping modifications.

Sustained operation

Under continuous vacuum the valve holds its preset limit reliably and reseats cleanly when pressure normalises. It is not suited for systems that demand adjustable relief settings or higher vacuum thresholds.

Questions about this item

At what vacuum level does the VV6 relief valve open under continuous operation?

The valve is preset to open at 86 in wc vacuum, providing consistent relief during sustained blower use.

How much heat or noise does the VV6 generate when installed in a blower line running all day?

As a passive mechanical valve with no moving actuator, it adds no measurable heat or audible noise to the system.

What piping must already be in place for the VV6 to thread directly into the blower inlet?

A 2 in female NPT fitting is required to match the valve's 2 in male NPT inlet connection.
