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).
