Series '150FCS'

Available with cast steel or stainless steel body in sizes 2" to 12" with ANSI 150# RF flanged ends for maximum operating pressures as follows:
PMO: (Maximum Operating Pressure)
275 psi @ 100 deg. F
245 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.
