D05T Compact Design Pressure
Regulating Valves

INSTALLATION INSTRUCTIONS

APPLICATION

The Honeywell Braukmann D05T 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 D05T 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 non-corroding unitized cartridge
insert contains all the working parts and is easily
replaceable.

The D05T is used for water or air regulation. It is not
suitable for steam.

Water Capacities (See Table 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 pres-

sure 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. D05T is required.

Changing the Outlet Pressure (See Fig. 1)

The D05T 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:

1. Close the supply shutoff valve and open a down-

INSTALLATION

When Installing this Product...

1. Read these instructions carefully. Failure to follow

them could damage the product or cause a hazard­ous condition.

2. Check the ratings given in these instructions and on

the product to make sure the product is suitable for
your application.

3. Installer must be a trained, experienced service

technician.

4. After installation is complete, check out the product

operation as provided in these instructions.

Procedure

1. Flush the system clear of sediment or debris.

2. Close the supply valve and downstream isolating

valve (if used).

3. Install the D05T with the arrow on the body pointing

in the direction of water flow. (The D05T can be
mounted in any position.)

The D05T can be installed directly onto the pipe by using
the female NPT threads on each end. If space limitations
restrict turning the D05T, install single- or double-unions.

NOTE: Heat from soldering can damage internal parts of

the D05T. Always remove the tailpiece(s) from
the D05T during soldering, or disassemble the
D05T prior to heating the casting.

Replacing the Cartridge (See Fig.

2)

The working parts of the D05T, including diaphragm, valve
seat, strainer, and disk are all contained in a replaceable
cartridge. To replace the cartridge:

1. Shut off the supply valve and open a downstream

faucet to relieve the system pressure.

To prevent injury and/or equipment damage,
loosen locknut and turn adjusting screw
counterclockwise to remove spring tension.

2. Loosen locknut and turn adjusting screw counter-

clockwise to remove spring tension.

3. Remove the bonnet and washer using an adjust-

able wrench, socket, or box-end wrench.

4. Remove the cartridge using two screwdrivers as

levers.

5. Attach new O-rings and screen onto the new car-

tridge. Make sure O-rings are properly installed
above and below the screen.

6. Insert the new cartridge. Do not scratch the sides.

7. Place the washer on top of the cartridge.

NOTE: The inner lip must be pointing up to avoid

damaging the diaphragm.

8. Replace the spring, spring cup, and bonnet.

9. Readjust the outlet pressure to the desired setting

by using the procedure described in Changing the
Outlet Pressure section.
