RAF 80 are piloted hydraulic valves activated by line pressure. The pilot valve has a spring- loaded membrane, which is exposed to the upstream pressure. The valve is normally closed. Only when the line pressure rises above a preset point, the RAF 80 opens to relieve the excessive pressure downstream without causing surge hazards. When the line pressure drops the RAF closes.
