DIAL-SET®PRESSURE REGULATING VALVES

APPLICATION

The Honeywell DS05C,D,G 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.

• Stand-In Pipe available for temporary installation

during construction or system flushing.

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, 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 a 12 gpm

capacity is required with only 10 psi falloff allowable, a 1/2 in.

DS05 is required.

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 the instructions.

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 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-unions or double-unions.

NOTE: Heat from soldering can damage internal parts of the

DS05. Always solder the tailpieces separately from

the DS05.

4. 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:

1. Loosen the locking screw by turning one turn 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.

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:

1. Shut off the supply valve and open a downstream faucet

to relieve the system pressure.

2. Loosen the setpoint screw by turning it counter-

clockwise (Do not remove this screw).

Fig. 2. Changing outlet pressure.

CAUTION

To prevent injury and/or equipment damage,

loosen locking screw and turn adjusting knob

counter-clockwise to remove spring tension.

3. Turn adjusting knob counter-clockwise to remove

spring tension.

4. Remove the bonnet and washer using an MT06A

Service Tool.

5. Remove the cartridge using two screwdrivers as levers.

Attach new O-rings and screen onto the new cartridge.

6. Make sure O-rings are properly installed above and

below the screen.

7. Insert the new cartridges. Do not scratch the sides.

8. Place the washer on top of the cartridge.

NOTE: The inner lip must be pointing up to avoid damaging

the diaphragm.

9. Replace the spring and bonnet.

10. Readjust the outlet pressure to the desired setting by

using the procedure described in Changing the

Downstream Pressure section.

Cleaning the Cartridge Screen

To clean the cartridge screen:

1. Shut off the supply valve and open a downstream faucet

to relieve the system pressure.

CAUTION

To prevent injury and/or equipment damage,

loosen locking screw and turn adjusting knob

counter-clockwise to remove spring tension.

Do not remove screw.

2. Loosen locking screw and turn adjusting knob counter-

clockwise to remove spring tension.

3. Remove the bonnet and washer using an MT06A service

tool.

4. Remove the cartridge using two screwdrivers as levers

as shown in Figure 3.

5. Remove and clean the cartridge screen.

6. Replace the cartridge screen and make sure the O-rings

are installed properly.

7. Carefully clean the cartridge seat area.

8. Insert the cartridge. Do not scratch the sides.

9. Place the washer on top of the cartridge.

NOTE: The inner lip must be pointing up to avoid damaging

the diaphragm.

10. Replace the spring and bonnet.

11. Readjust the outlet pressure to the desired setting by

using the procedure described in Changing the Outlet

Pressure section.

Recalibration

If the dial knob assembly has been dismantled, recalibration is

necessary. Recalibrate as follows:

1. Install a good quality pressure gauge at the gauge tap

connection.

2. Open supply pressure and adjust spindle until the gauge

shows 60 psi.

3. Reassemble dial ring and adjustment knob so dial reads

60 psi.

TROUBLESHOOTING

Table 2 provides a troubleshooting guide for the DS05 Dial 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 goes away.

Will not hold pressure. •Clean the filter cartridge as described in the installation section.

Chatters. •Replace screen and O-rings.

•Replace the cartridge as shown in Figure 3.

Freezes up. •Replace bonnet or cartridge if damaged.

•To avoid further 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 temperature 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 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 Dial-Set from

moisture and debris.

Once the outlet pressure is set, the DS05 automatically

regulates to maintain the downstream pressure. See Figure 5

for the internal construction of the DS05.

Minimum ambient rating is 33° F (1° C).
