Watts 0009217 1/2" Water Pressure Reducing Valve 25/75 PSI

The Watts 0009217 1/2 Inch Water Pressure Reducing Valve is an essential product for managing and controlling the pressure of water in different plumbing systems especially those related to HVAC systems. This valve can be used to regulate incoming water pressure to a safer prescribed range of 25-75 PSI because it will guard delicate installations like plumbing fixtures/water systems, water heaters, and irrigation systems against water pressure-related damages. This pressure reducing valve works through a piston and a diaphragm system within the same valve body. Upon admission of water in the dome, pressure increases and pushes the piston against the diaphragm controlling the flow of water largely reducing the downstream pressure.
