Check valve SW NPT RF RTJ Bolted Bonnet Integral Seat API 602 Forged Steel Valve
API 602 Check Valve
Check valves serve an important application—namely to prevent flow in one direction while allowing it in the other. A check valve is self-actuated and designed to prevent fluid from flowing back into the system (prevent reverse flow). Real-life applications include preventing backflow into an injection line or into a pump. The fluid flow opens the valve by forcing a disk or ball in one direction. When the flow stops, the disk or ball is seated and closes the valve. They can be installed in horizontal or vertical upward flow piping.
Design Features
  • Valves in accordance with API-602.
  • Socket Weld, Threaded, Combined or Flanged RF or RTJ ends.
  • Bolted Bonnet or Welded Bonnet options.
