This 4 inch globe pattern class 150 flanged epoxy coated pressure reducing and downstream surge control valve, model 115-7, is designed to automatically reduce a fluctuating higher inlet pressure to a constant lower downstream pressure regardless of varying flow rates, and quickly modulate toward a closed position when a sudden downstream high pressure condition occurs. The quick closing action of the valve limits possible damaging high inlet pressure from passing through the valve to downstream piping.
