The hydrant control valve shall function to reduce a higher upstream pressure to a constant, lower downstream pressure regardless of fluctuations in supply or demand. It shall be equipped with a two-way hydraulic valve that will allow the valve to open when pressurized. It shall also be equipped with a high capacity surge control pilot to close the valve quickly in the event of sudden reduction in flow. The valve will open automatically in the event of pressure reversal. The OCV 114-3 is a control valve specifically designed for aircraft refueling service. Known as either a refueling or a hydrant control valve, it is the typical control valve used on pantograph refueling systems. It performs the following functions:
– Opens and closes via hydraulic deadman control
– While open, modulates to control downstream pressure at a predetermined set point
– Closes rapidly to prevent undue pressure buildup due to a rapid reduction in demand
