DS05
Dial Set Pressure Regulating Valves
APPLICATION
The Honeywell Braukmann DS05 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).
FEATURES
•Built-in, factory calibrated outlet pressure adjustment
dial.
•Noncorroding unitized cartridge contains all working
parts and is easily replaceable.
•Includes built-in strainer and thermal bypass.
•Balanced seat construction provides superior
pressure regulation.
•Inlet and outlet are internally threaded female NPT, and
externally threaded for use with union assemblies.
•Gauge tap included on all models.
•U06P Stand-In Pipe available for temporary
installation during construction or system flushing.

DS05 DIAL SET PRESSURE REGULATING VALVE
62-3041—2

Water Capacities (See Table 1.)
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 (gpm), and
3. Allowable reduced pressure falloff in psi.
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 ft/sec; industrial use, 7 to 15 ft/sec; boiler feed,
7 to 15 ft/sec.
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. DS05 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 one is installed).
Install the DS05 with the arrow on the body pointing in
the direction of water flow. (The DS05 can be mounted
in any position.)
The DS05 can be installed directly onto the pipe by using the
female NPT threads on each end. If space limitations restrict
turning the DS05, install single- or double-unions.
NOTE: Heat from soldering can damage internal parts of
the DS05. Always solder the tailpieces separately
from the DS05.
Open the supply valve slowly and check for leakage
and proper operation of the DS05.
Changing the Downstream Pressure
(See Fig. 2)
Remove the dust cap from the DS05. The DS05 is factory set
to 60 psi.
To adjust the outlet pressure to a desired setting:
Loosen the locking screw by turning one turn counter-
clockwise (Do not remove this screw.)
Turn the adjusting knob counterclockwise to
reduce pressure or clockwise to increase
pressure.
Lock the setting by turning the locking screw
clockwise .
Replace the dust cap over the dial.
MAINTENANCE
Replacing the Cartridge (See Fig. 3)
The working parts of the DS05, including diaphragm, valve
seat, strainer, and disk are all contained in a replaceable
cartridge. To replace the cartridge:
Shut off the supply valve and open a downstream
faucet to relieve the system pressure.
Loosen the setpoint locking screw by turning
counterclockwise (Do not remove this screw.)

TROUBLESHOOTING
Table 2 provides a troubleshooting guide for the DS05 Dial Set Pressure Regulating Valve.
Table 2.Troubleshooting the DS05 Dial Set Pressure Regulating Valve.
Problem Solution
Whistling noise. • Slightly increase or decrease the outlet pressure until the noise disappears.
Will not hold pressure. • Clean the filter cartridge as described in the Installation section.
Chatters. • Replace the screen and O-rings.
• Replace the cartridge as shown in Fig. 3.
Freezes up. • Replace bonnet or cartridge if damaged.
• To avoid future freeze-up:
— Temporarily (slightly) open a downstream faucet if the DS05 will be exposed
to temperatures below 32°F (0°C). The slight water flow will eliminate
freeze-up.
— Move the DS05 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.
• DS05 is functioning properly. No action is necessary. The pressure decrease is
characteristic of all direct acting pressure regulating valves and is referred to as
falloff.

OPERATION
The Honeywell Braukmann DS05 Dial Set Pressure
Regulating Valve is a balanced, direct acting pressure
regulating valve. The DS05 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 knob 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. A factory-
calibrated dial is built into the adjustment mechanism to allow
outlet pressure (no flow) to be set without a gauge. A locking
screw maintains the setting. A black plastic cover is provided
to conceal the setting and protect the DialSet from moisture
and debris.
Once the outlet pressure is set, the DS05 automatically
regulates to maintain the downstream pressure. See Fig. 5 for
the internal construction of the DS05.
NOTE: Minimum ambient rating is 33°F (1°C).
