Watts 2300 User Manual
Lead free, Series 2300, Direct operated water pressure reducing valves

For Commercial and Industrial Applications
ES-2300
Series 2300 Direct Operated Water Pressure Reducing Valves are
designed for dead-end water service where the flow is intermittent
and changes rapidly, as on domestic water system. This Series
is also installed to regulate the flow of water to such fast acting
equipment as flushometers and snap cocks. The Series 2300 is
recommended where city water pressure is to be reduced to sup-
ply plumbing fixtures to prevent violent pressure fluctuations. The
2300 features Lead Free* construction to comply with Lead Free*
installation requirements.
