APPLICATION
The Honeywell Braukmann D05 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 ideally suited for new
residential and light commercial construction, drip
irrigation, and applications requiring highly sensitive and
accurate regulation.
The wide inlet pressure range of the D05 gives flexibility
without compromising reduced outlet pressure accuracy
or capacity. The superior balanced single seat design
maintains a constant outlet pressure over a wide range
of inlet pressures. The noncorroding unitized cartridge
insert contains all the working parts and is easily
replaceable.
The D05 is used for water or air regulation. It is not
suitable for steam.

Water Capacities (SeeTable 1):
The suitability of a given regulator size is dependent
on the pressure requirements of each installation.
To determine 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 (gpm), 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
12 gpm capacity is required with only 10 psi
falloff allowable, a 1/2 in. D05 is required.

INSTALLATION
When Installing this Product...
Read these instructions carefully. Failure to follow
them could damage the product or cause a
hazardous condition.
Check the ratings given in these instructions and
on the product to make sure the product is suitable
for your application.
Installer must be a trained, experienced service
technician.
After installation is complete, check out the product
operation as provided in these instructions.
Procedure
Flush the system clear of sediment or debris.
Close the supply valve and downstream isolating
valve (if used).
Install the D05 with the arrow on the body pointing
in the direction of water flow. (The D05 can be
mounted in any position.)
The D05 can be installed directly onto the pipe by using
the female NPT threads on each end. If space limitations
restrict turning the D05, install single- or double-unions.
NOTE: Heat from soldering can damage internal parts
of the D05. Always remove the tailpiece(s) from
the D05 during soldering, or disassemble the
D05 prior to heating the casting.
aVelocity in feet per second is based on schedule 40 pipe size. recommended pressure falloff for general use is
approximately 104 kPa (15 psi). Recommended velocities for the flow of water: Residential and general use, 5 to 10
feet per second; industrial use, 7 to 15 feet per second; boiler feed, 7 to 15 feet per second.
Open the supply valve.
Changing the Outlet Pressure (See Fig. 1)
The D05 is factory set to 60 psi. To change the outlet
pressure, turn the adjusting bolt counterclockwise
to reduce pressure or clockwise to increase
pressure.
To adjust the outlet pressure to a desired setting:
Close the supply shutoff valve and open a down-
stream faucet to relieve static pressure in the line.
Install a pressure gauge to the gauge tap on D05G
models, or temporarily with a downstream hose bib
on other D05 models.
Loosen the locknut by turning counterclockwise
two turns.
Turn the adjusting bolt counterclockwise
several turns to make sure the setting is below the
desired setting.
Close all downstream valves and/or faucets and
slowly open the supply valve until fully open.
Turn the adjusting bolt clockwise to gradually
increase the pressure until the gauge indicates the
desired outlet pressure (under no flow condition).
Reopen a downstream valve. During flow, there
will normally be a pressure falloff of 3 to 15 psi
depending upon the amount of water flow.
Tighten the locknut by turning clockwise until
tight. Do not overtighten.

D05 PRESSURE REGULATING VALVES
OPERATION
The Honeywell Braukmann D05 is a balanced, direct
acting pressure regulating valve. The D05 provides
constant downstream pressure regardless of varying
inlet pressures and downstream flow demands.
The spring force holds the valve in the open position until
downstream pressure, sensed by a port, is sufficient to
press on the underside of the diaphragm and close the
valve. As downstream pressure drops due to demand,
the force on the diaphragm is reduced and the valve
opens. Adjustment is made by manually turning the
adjustment screw clockwise to increase the spring
force and require a higher downstream pressure to close
the valve. Similarly, reducing the spring force lowers the
outlet set pressure.
Once the outlet pressure is set, the D05 regulates to
maintain that pressure downstream. See Fig. 4 for the
internal construction of the D05.
Cleaning the Cartridge Screen
To clean the cartridge screen:
Shut off the supply valve and open a downstream
faucet to relieve the system pressure.
CAUTION
To prevent injury and/or equipment damage,
loosen locknut and turn adjusting screw
counterclockwise to remove spring tension.
Loosen locknut and turn adjusting screw
counterclockwise to remove spring tension.
Remove the bonnet and washer using an
adjustable wrench, socket, or box-end wrench.
Remove the cartridge using two screwdrivers as
levers as shown in Fig. 3.
Remove and clean the cartridge screen.
NOTE: D05G models can be cleaned partially by
removing the gauge tap plug and using
an air hose to blow air into the unit.
Replace the cartridge screen and make sure the
O-rings are installed properly.
Carefully clean the cartridge seat area.
Insert the cartridge. Do not scratch the sides.
Place the washer on top of the cartridge.
NOTE: The inner lip must be pointing up to avoid
damaging the diaphragm.
쐅Replace the spring, spring cup and bonnet (see
Fig. 3).
쐈Readjust the outlet pressure to the desired setting
by using the procedure described in Changing the

Problem Solution
Whistling noise. • Slightly increase or decrease the outlet pressure until the noise disappears.
Will not hold pressure. • Clean the filter cartridge as shown on page 2.
•Open the guage tap and blow out any dirt (D05G only).
Chatters. • Replace the screen and O-rings.
•Replace the cartridge as shown on page 2.
Freezes up. • Replace bonnet or cartridge if damaged.
•To avoid future freeze-up:
—Temporarily (slightly) open a downstream faucet if the D05 is going to be
exposed to temperatures below 32°F (0°C). The slight water flow will
eliminate freeze-up.
—Move the D05 to a location with an ambient temperature above 32°F
(0°C) if it is currently exposed to prolonged temperatures below 32°F
(0°C).
Pressure gauge measures a lower
pressure under flow conditions than
was originally set during static
conditions.
•D05 is functioning properly. No action is necessary. The pressure decrease
is characteristic of all direct acting pressure regulating valves and is referred
to as fall-off.
