Pressure Reducing & Surge Control Valve 

The pressure reducing & surge control valve shall function to reduce a higher upstream pressure to a constant, lower downstream pressure and prevent the downstream pressure from rising too far in the event of sudden reduction of flow. The OCV 127-5 should be used in fuel delivery systems where a pressure must be reduced to a manageable level and demand can diminish rapidly (dead end service).

  • Reduces a higher inlet pressure to a lower outlet pressure
  • Constant outlet pressure over wide flow range
  • Minimizes downstream pressure build-up in the event of sudden reduction in flow
  • Pilot-operated main valve not subject to pressure fall-off
  • Can be maintained without removal from the line
  • Adjustable opening/response speed
  • Factory tested and can be pre-set to your requirements
