Description
The Honeywell PP902C1009/U Pressure Reducing Valve is a control unit used to regulate incoming water pressure for plumbing, hydronic, and HVAC systems while maintaining a controlled downstream pressure level. It automatically reduces higher inlet pressure to a preset operating range, protecting connected equipment and piping from excessive pressure conditions. This valve is installed in water supply lines ahead of boilers, water heaters, or other pressure-sensitive equipment where stable pressure is required. It provides water flow, supports consistent system operation, and assists with protecting connected components during service.
