The Model PRV-1A Pressure Reducing Valves, 2 in. to 8 in. (DN50 to DN200), are factory-assembled and fully trimmed valve arrangements for
pressure control. They are used on water filled pipes, where it is necessary to reduce a higher inlet pressure to a lower delivery pressure under static and/or residual flowing conditions.The Model PRV-1A Valve is intended to automatically maintain the outlet “set pressure” (static and residual) within a close range, regardless of fluctuations in the higher pressure inlet line or varying flow rates.
