WATER CAPACITIES
The suitability of a given regulator size is dependent on the pressure requirements where it will operate. For the pressure regulator valve
size required for a specific installation, determine the following:
1. Pressure differential between inlet and outlet pressure in pounds per square inch (psi),
2. Capacity in gallons per minute, and
3. Allowable reduced pressure falloff in psi. Given these variables, use Table 2 to determine the proper size pressure regulator
valve for your application.
Example: An installation has 135 psi inlet pressure, 60 psi outlet pressure (75 psi pressure differential). If a 15 gpm capacity is required
with only 10 psi falloff allowable, a 3/4 in. FK06 is required.

Capacities are based on a 100 psi supply pressure and a difference of 50 psi or more between the initial supply pressure and the reduced
no-flow pressure. Check local water pressures before selection.
