Two-Stage Preset Valve

The two-stage preset valve shall open in one stage and close in two stages based on signals from the preset register. The OCV 110-9S is specifically designed for fuel loading systems and performs the following functions:

  • Electrical opening and two-stage shutdown via preset register
  • Air Eliminator Functions – main valve goes closed when air is detected at the air eliminator head and will re-open when all air has been exhausted from the air eliminator. This prevents air from passing through a meter and causing inaccurate readings
  • LPG/LNG Functions – upstream pressure is held at a fixed value above vapor pressure to prevent flashing at the flowmeter
  • Adjustable flow setting for 2nd stage dwell
  • Can be controlled by mechanical or electronic presets
  • Factory tested
  • Junction box options are available, with explosion proof ratings
  • Two-stage electronic opening options are available
  • Class 1 Div 1 (standard), Class 1 Div 2 – ATEX, IECEX (optional)
