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).
