DS06 Installation Instructions

DS06 LOW LEAD CONTENT DIAL SET PRESSURE REGULATING VALVES
33-00014EF—03 2
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 pres-
sure 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.
Table 1. Water Capacities.
Procedure
1. Flush the system clear of sediment or debris.
2. Close the supply valve and downstream isolating
valve (if one is installed).
3. Install the DS06 with the arrow on the body pointing
in the direction of water flow. Install in horizontal
pipework with filter bowl downwards.
The DS06 can be installed directly onto the pipe by using
the female NPT threads on each end. If space limitations
restrict turning the DS06, install single- or double-unions.
NOTE: Heat from soldering can damage internal
parts of the DS06. Always solder the
tailpieces separately from the DS06.
4. Open the supply valve slowly and check for leakage
and proper operation of the DS06.
