DS06 LOW LEAD CONTENT DIAL SET PRESSURE REGULATING VALVES
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 1 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. DS06 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.
Procedure
1. Flush the system clear of sediment or debris.
Units
2. Close the supply valve and downstream isolating
21
valve (if one is installed).
3. Install the DS06 with the arrow on the body
40
pointing in the direction of water flow. Install,
48
preferably, in horizontal pipework with filter bowl
70
downwards - vertical installation also possible.

The DS06 can be installed directly onto the pipe by
400
using the female NPT threads on each end. If space
limitations restrict turning the DS06, install single- or
double-unions.
