INSTALLATION INSTRUCTIONS
APPLICATION
The Honeywell DS06 Dial Set® Pressure Regulating
Valve is a high quality pressure regulating valve that
maintains a constant outlet pressure over a wide
range of inlet supply pressures. It is suitable for
potable water and irrigation applications. The
downstream pressure adjustment dial eliminates the
need for a pressure gauge when adjusting the
pressure setting (static pressure only).

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

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.

Units
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.
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,
preferably, in horizontal pipework with filter bowl
downwards - vertical installation also possible.
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.
Changing the Downstream Pressure (See Fig. 1)
Remove the dust cap from the DS06. The DS06 is
factory set to 60 psi.
To adjust the outlet pressure to a desired setting:
1. Loosen the locking screw by turning counter-
clockwise (Do not remove this screw.)
2. Turn the adjusting knob counter-clockwise
to reduce pressure or clockwise to
increase pressure.
3. Lock the setting by turning the locking screw
clockwise .
4. Replace the dust cap over the dial.
8. Remove cartridge using a pliers as a lever.
9. Reassemble bonnet in reverse order.
Recalibrate
If the dial knob assembly has been disassembled
recalibration is necessary.
1. Close shutoff valve on inlet.
2. Release pressure on outlet side (e.g. through
water tap).
3. Close shutoff valve on outlet.
4. Remove dust cap.
5. Loosen slotted screw (do not remove screw).
6. Fit pressure gauge.
7. Slowly open shutoff valve on inlet.
8. Set desired outlet pressure (e.g. 60 psi).
9. Align scale (e.g. 60 psi) in middle of viewing win-
dow.
10. Retighten slotted screw.
11. Slowly open shutoff valve on outlet.
Fig. 1. Changing outlet pressure.
Replacing the Cartridge (Fig. 2)
The working parts of the DS06, including diaphragm,
valve seat, strainer, and disk are all contained in a
replaceable cartridge. To replace the cartridge:
1. Close shutoff valve on inlet.
2. Release pressure on outlet side (e.g. through
water tap).
3. Close shutoff valve on outlet.
4. Loosen slotted screw (do not remove the screw).
To prevent injury and/or equipment damage,
loosen locknut and turn adjusting screw
counter-clockwise to remove spring
tension.
5. Slacken tension in compression spring by
turning counter clockwise until it does not move
anymore.
6. Unscrew Bonnet.
7. Remove slip ring.

OPERATION
DS06 is a spring loaded pressure reducing valve that
operates by means of force equalizing system. The
force of a diaphragm operates against the force of an
adjustment spring. If the outlet pressure and therefore
diaphragm force fall because water is dawn, the then
greater force of the spring causes the valve to open.
The outlet pressure then increases until the forces
between the diaphragm and the spring are equal
again. The inlet pressure has no influence in either
opening or closing the valve. Because of this, inlet
pressure fluctuation does not influence the outlet
pressure, thus providing inlet pressure balancing. See
Fig. 4 for the internal construction of the DS06.
NOTE: Minimum ambient rating is 33° F (1° C).
