VG7000 Series Bronze Control Valves Installation Instructions2

Dimensions

IMPORTANT: Take care to prevent foreign material

such as weld slag, thread burrs, metal chips, and

scale from entering the piping system. This debris

can damage or severely impede the operation of the

valve by embedding itself in the seats, scoring the

valve, and ultimately resulting in seat leakage. If the

debris becomes embedded in the seats, subsequent

flushing and filtering of the piping system with the

valve installed does not remedy the problem.
