WWT849215, Watts, 2 1/2 Pressure Reducing Control Valve With Downstream Surge Control Feature, Thread

This 2 1/2 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. It has threaded connections.
