Item Number 125FCSIVR-3, Cast Iron Globe Style Silent Check Valve On Colton Industries

Series '125FCSI'

Available in sizes 2" to 16" with ANSI 125# FF flanged ends for maximum operating pressures as follows:
PMO: (Maximum Operating Pressure)
2" to 12" 200 psi @ 150 deg. F.
125 psi @ 450 deg. F.
14" to 16" 150 psi @ 150 deg. F.
100 psi @ 250 deg. F.

Notes:

These valves are designed for horizontal and vertical flows.
The conical spring design allows the plug greater travel, resulting in better flow characteristics than valves of conventional design.
These valves can be machined to accept an optional soft seat (usually Buna-N) for bubble tight shut-off.
