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
