The WATTS Pressure Reducing Valve is designed to regulate and reduce the incoming water pressure in a plumbing system to a specific, adjustable level. Here's a description of the key features and specifications of the WATTS Pressure Reducing Valve:

  1. Pressure Range: The valve is capable of reducing water pressure from a maximum of 500 kPa (kilopascals) to a lower, adjustable pressure level.

  2. Material: This pressure reducing valve is constructed from Lead-Free DR (Dezincification Resistant) Brass. This material is safe for potable water systems and helps prevent the corrosion and degradation of the valve over time.

  3. Adjustable Pressure: The valve is adjustable, meaning you can set the desired outlet pressure by turning a screw or knob on the valve. This allows you to customize the water pressure to meet the specific needs of your plumbing system.

  4. Regulation: The valve is designed to provide stable and consistent water pressure downstream, even when the incoming pressure varies. It helps prevent pressure spikes that can damage appliances and plumbing fixtures.

  5. Size: The valve is available in various sizes to accommodate different pipe diameters and flow rates. It's essential to choose the right size to ensure proper pressure regulation for your system.

  6. Applications: Pressure reducing valves like this one are commonly used in residential, commercial, and industrial plumbing systems. They are particularly useful in areas with high water pressure, as they protect pipes, fixtures, and appliances from potential damage.

  7. Lead-Free Compliance: The use of Lead-Free DR Brass ensures that the valve meets or exceeds lead-free regulations and is safe for use in drinking water systems.

  8. Installation: The valve is typically installed on the main water supply line entering a building or at specific points within the plumbing system where pressure regulation is necessary.

  9. Maintenance: Regular maintenance may be required to ensure the valve continues to function correctly. This can include periodic inspection, cleaning, and adjustments as needed.

  10. Pressure Gauge: Some pressure reducing valves come with an integrated pressure gauge to monitor the outlet pressure easily.

Always follow the manufacturer's instructions and local plumbing codes when installing and maintaining pressure reducing valves. Proper installation and maintenance are essential to ensure the longevity and effectiveness of the valve in regulating water pressure within your plumbing system.
