Watts Pressure Reducing Valve Series 2300

Direct Operated Water Pressure Reducing Valve

Series 2300 Direct Operated Water Pressure Reducing Valves are used in commercial and industrial applications to regulate the flow of water to dead-end services where the flow is intermittent and changes rapidly.

Features
  • Self-contained design requires no control lines
  • Self-aligning design eliminates dirt collection point because there’s no need for a stem guide in the bottom flanges
  • Large pressure plate gives ample diaphragm support for longevity
