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.
