PMO: (Maximum Operating Pressure)
2" to 6" 400 psi @ 150 deg. F
250 psi @ 400 deg. F.
8" to 12" 200 psi @ 150 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.
