Watts 0009489 1" Lead Free Water Pressure Reducing Valve LFN45B-1

The Watts 0009489 Reducing Valve 1” LFN45B-1 is an essential part in HVAC systems and fluid control systems meant to ensure a steady downstream water pressure. In terms of its applications, it serves the role of a reducing valve in that it is designed to admit a high pressure, and output a lower pressure within a range of 25-75 PSI. This is done by an internal means normally a spring loaded diaphragm or piston that opens the valve depending on the downstream pressure.
