Pressure Reducing Valves

Pressure Reducing Valves (PRV) regulate water pressure entering the fire protection system from the main water supply.

Field Adjustable PRV (1 1/2" & 2")

Field Adjustable Pressure Reducing Valves regulate incoming water pressure and can be adjusted in the field.

Factory Set PRV (1 1/2" & 2")

NOTE: When choosing a Factory Set Pressure Reducing Valve, you must choose a Bonnet that corresponds with your application's specifications (refer to chart below).

Factory Set Pressure Reducing Valves regulate incoming water pressure and come pre-configured from the factory.

Choosing the proper Bonnet:
When choosing the Bonnet for the Pressure Reducing Valve refer to the charts and the following procedure:

  1. Determine the demand in gallons per minute required downstream of the valve.
  2. To determine the static outlet pressure, locate the static chart. Determine the valve inlet static pressure shown on the vertical axis and draw a horizontal line from that pressure to the appropriate curve determined above. Then, draw a vertical line down to the horizontal axis and read the static outlet pressure.
  3. Determine the standpipe residual or "flow pressure" at the valve inlet.
  4. Locate the appropriate flow chart based on GPM required and body style.
  5. Locate the inlet residual pressure on the vertical axis of the chart and draw a horizontal line from this pressure across the chart.
  6. Locate the desired valve outlet residual pressure on the horizontal axis of the chart and draw a vertical line from this pressure.
  7. The curve nearest the intersection of the two drawn lines is the appropriate type for the valve.
