SITE SELECTION
GF Piping Systems recommend isolation valves (gate or block type) be installed upstream & downstream
of the NeoFlow pressure reducing valve to facilitate isolation of the valve for maintenance and repairs. A
downstream hydrant and an upstream flow meter are also recommended.
2.2.1
BYPASS LINE
For existing installations with bypass lines, GF Piping Systems recommends the configuration
shown below. Isolation valves 1 and 6
must be securely closed
before the valve on the bypass
line is commissioned.
