WWT211303, Watts, 2 Pressure Reducing Control Valve With Downstream Surge Control Feature

This 2 IN Watts 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 minimizes possible damaging high inlet pressure from passing through the valve to downstream piping.
