PRODUCT DATA

The Honeywell DS06D,G Dial Set 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 potable water and irrigation applications requiring accurate regulation.

The wide outlet pressure range, high inlet pressure, and compact design allow flexibility in installation and application.

To facilitate setup and checkout, the DS06D,G features a calibrated outlet pressure set dial that allows outlet pressure adjustments without the use of a gauge in most applications.

DS06D,G DIAL SET PRESSURE REGULATING VALVE

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, calculate 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.

Table 1. Water Capacities.

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 30 gpm capacity is required with only 10 psi falloff allowable, a 1-1/2 in. DS06D,G is required. This pressure regulator valve allows a flow capacity up to 46 gpm with a 10 psi falloff at a no flow pressure differential of 75 psi.

INSTALLATION

CAUTION

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 you application.

3. Installer must be a trained, experienced service technician.

4. After installation is complete, check out the product as provided in these instructions.

Procedure

1. Flush the system clear of sediment and debris.

2. Close the supply valve and downstream isolating valve

(if existing).

3. Install the DS06D,G with the arrow pointing in the direction of water flow (any mounting orientation is acceptable). The DS06D,G can be installed directly onto a pipe using the female NPT threads on each end or by using single or double unions, if required. (One union is provided.)

Adjusting Outlet Pressure (See Fig. 2)

The DS06D,G is factory set at 60 psi (no flow). Follow this procedure if adjustment is required:

Heat from soldering can damage internal parts. Always remove tailpiece or solder adapter prior to soldering.

4. Open the supply valve slowly and open the downstream

valve, if provided.

5. Check for leaks at connections and correct, if necessary.

1. Remove dust cap and loosen locking screw one turn

counterclockwise. Do not remove the locking screw.

2. Turn adjusting knob clockwise to increase pressure and counterclockwise to decrease pressure. When decreasing pressure, a slight downstream flow is necessary to relieve pressure. Turn until dial scale indicates desired pressure (no flow set pressure).

3. Tighten locking screw and replace dust cap.

MAINTENANCE AND REPAIR

Replacing DS06D,G Cartridge

The working parts of the DS06D,G, including diaphragm, valve seat, strainer, and disk, are all contained in a replaceable cartridge. To replace the cartridge:

1. Close the supply valve and relieve the downstream pressure.

2. Remove the dust cap. Relieve pressure on the spring by loosening the locking screw (do not remove) and turning the adjusting knob counterclockwise until no resistance is felt.

3. Remove the bonnet (See Fig. 3) by turning counterclockwise. Remove the spring and protection washer (See Fig. 4).

4. Remove the cartridge using two screwdrivers as levers (See Fig. 4). Remove the cartridge O-ring.

5. Remove the strainer cup (See Fig. 5).

6. Remove the strainer and strainer support. Remove the

U-seal.

7. Clean the inside of the valve and all the components.

NOTE: Replace the U seal (provided in the repair kit) for a

complete cartridge repair.

DO NOT REMOVE ADJUSTING KNOB. SETPOINT READOUT WAS CALIBRATED IN THE FACTORY AND SET AT 60 PSI. REMOVING THE ADJUSTING KNOB CANCELS THIS CALIBRATION – AND REQUIRES RECALIBRATION USING A PRESSURE GAUGE.

MAXIMUM INLET PRESSURE IS 400 PSI. OUTLET PRESSURE RANGE IS 15 TO 130 PSI.

8. Replace the U-seal by placing the U-seal on the strainer support and pushing the assembly into place. The U-seal open end must face the strainer support (See Fig. 7). Replace the strainer onto the strainer support.

9. Assemble the strainer cup O-ring onto the strainer cup and insert the assembly into the body of the valve. Tighten securely using the service tool. Do not over torque.

10. Replace the new cartridge ensuring the O-ring is in place.

11. Replace the protection washer with the lip up (away from the valve body). See Fig. 6.

12. Replace the spring and bonnet. Tighten the bonnet using the service tool. Do not over torque.

13. Adjust the outlet pressure following the procedure in Adjusting the Outlet Pressure section.

Cleaning Strainer Screen

To clean the strainer screen:

1. Close the supply valve and relieve the downstream pressure.

2. Remove the strainer cup (See Fig. 5).

3. Remove the strainer and the strainer support. Do not

remove the U-seal.

4. Clean the strainer cup and the strainer.

5. Replace the strainer on the strainer support. Insert the

assembly into the valve.

6. Assemble the strainer cup O-ring onto the strainer cup and insert the assembly into the body of the valve. Tighten securely using the service tool. Do not over torque.

Recalibrating DS06D,G

If the adjusting knob and dial are accidentally removed, the dial must be recalibrated as follows:

1. Follow the procedure in Adjusting the Outlet Pressure section. Set the pressure on the gauge at 60 psi (or another convenient pressure).

2. Reassemble the dial ring onto the bonnet with the pressure on the ring matching the pressure gauge.

3. Assemble the locking screw and tighten. Replace the dust cap.

OPERATION

The Honeywell DS06D,G Dial Set is a balanced, direct acting pressure-regulating valve. It 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 (under no flow condition) to be set without a gauge. A lock screw maintains the setting. A black plastic cover is provided for additional protection.

When the outlet pressure is set, the DS06D,G automatically regulates to maintain the downstream pressure.

TROUBLESHOOTING

Table 2 is a troubleshooting guide for the DS06D,G Pressure Regulating Valves.

Table 2. Troubleshooting DS06D,G Pressure Regulating Valves.

Problem Cause Solution

Will not hold pressure or pressure gradually rises.

Frozen. Valve exposed to freezing temperatures

Pressure gauge measures a lower pressure under flow conditions than set pressure at no flow.

Low capacity, low outlet pressure. Screen blocked with debris.

Thermal expansion. Debris on valve seat. Damaged valve seat.

below 32° F (0° C).

This is normal and characteristic of direct-acting pressure-reducing valves.

Valve undersized.

Install a thermal expansion tank to limit pressure rise. Clean valve. Replace cartridge.

Inspect and replace any damaged components. Move valve to a location that remains above freezing.

No action is necessary.

Clean screen. Check capacity versus requirements and increase valve size.
