DS05Dial Set Pressure Regulating ValvesAPPLICATIONThe Honeywell Braukmann DS05 Dial Set PressureRegulating Valve is a high quality pressure regulatingvalve that maintains a constant outlet pressure over awide range of inlet supply pressures. It is suitable forpotable water and irrigation applications. Thedownstream pressure adjustment dial eliminates theneed for a pressure gauge when adjusting the pressuresetting (static pressure only).SPECIFICATIONSModel:DS05 Dial Set Pressure Regulating Valves.Construction Materials:Body: Bronze.Internal Parts: Stainless steel and engineeredplastics.Regulator Mechanism: Fabric-reinforced diaphragm.Seat Design:Balanced single seat construction.Inlet Pressure (Maximum):400 psi maximum.Reduced Pressure Range:15 to 150 psi (1/2 in. to 1 in.).15 to 130 psi (1-1/4 in.).Outlet Pressure:Factory set at 60 psi.Dial Calibration:± 4 psi.Differential:14 psi minimum (inlet to outlet).Reduced Ratio:10:1 maximum.Fluid Temperature (Maximum):Air: 158°F (70°C).Water: 180°F (82°C).Ambient Temperature Range:33°F to 140°F (1°C to 60°C).INSTALLATION INSTRUCTIONSConnections:Can be configured as female thread-by-thread, single- ordouble-union, NPT threaded or sweat.Strainer Screen Size:0.032 in. (0.8 mm).Gauge Tap:1/4 in. NPT.Approvals:ASSE (Std. 1003) Certified.IAPMO, CSA, and City of L.A. Listed.Water Capacities (See Table 1.)The suitability of a given regulator size is dependent onthe pressure requirements where it will operate. For thepressure regulator valve size required for a specificinstallation, determine the following:1. Pressure differential between inlet and outletpressure in pounds per square inch (psi),2. Capacity in gallons per minute (gpm), and3. Allowable reduced pressure falloff in psi.Given these variables, use Table 1 to determine theproper size pressure regulator valve for your application.Example: An installation has 135 psi inlet pressure, 60 psioutlet pressure (75 psi pressure differential). If 12gpm capacity is required with only 10 psi falloffallowable, a 1/2 in. DS05 is required.INSTALLATIONWhen Installing this Product... Read these instructions carefully.

Recommended pressure falloff for general use is approximately104 kPa (15 psi). Recommended velocities for the flow of water: Residential and general use, 5 to 10 ft/sec; industrial use, 7 to15 ft/sec; boiler feed, 7 to 15 ft/sec.Procedure Flush the system clear of sediment or debris. Close the supply valve and downstream isolatingvalve (if one is installed). Install the DS05 with the arrow on the bodypointing in the direction of water flow. (The DS05can be mounted in any position.)The DS05 can be installed directly onto the pipe by usingthe female NPT threads on each end. If space limitationsrestrict turning the DS05, install single- or double-unions.NOTE:Heat from soldering can damage internal partsof the DS05. Always solder the tailpiecesseparately from the DS05. Open the supply valve slowly and check forleakage and proper operation of the DS05.Changing the Downstream Pressure(See Fig. 1)Remove the dust cap from the DS05. The DS05 isfactory set to 60 psi.To adjust the outlet pressure to a desired setting: Loosen the locking screw by turning counterclockwise(Do not remove this screw.) Turn the adjusting knob counterclockwise toreduce pressure or clockwise to increasepressure. Lock the setting by turning the locking screw clockwise. Replace the dust cap over the dial.Replacing the Cartridge (See Fig. 2)The working parts of the DS05, including diaphragm,valve seat, strainer, and disk are all contained in areplaceable cartridge. To replace the cartridge: Shut off the supply valve and open a downstreamfaucet to relieve the system pressure. Loosen the setpoint locking screw by turningcounterclockwise (Do not remove this screw).CAUTIONTo prevent injury and/or equipment damage,loosen locknut and turn adjusting screwcounterclockwise to remove springtension. Loosen locknut and turn adjusting screw counterclockwiseto remove spring tension. Remove the bonnet and washer using the MT06AService Wrench. Remove the cartridge using two screwdrivers aslevers.62-3042 2

Troubleshooting the DS05 Dial Set Pressure Regulating Valve.SolutionWhistling noise. • Slightly increase or decrease the outlet pressure until the noise disappears.Will not hold pressure. • Clean the filter cartridge as shown on page 2.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 is going tobe exposed to temperatures below 32°F [0°C]. The slight water flow willeliminate 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 lowerpressure under flow conditions thanwas originally set during staticconditions.• DS05 is functioning properly. No action is necessary. The pressuredecrease is characteristic of all direct acting pressure regulating valves andis referred to as falloff.62-3042 4

DS05 DIAL SET PRESSURE REGULATING VALVE60DUST CAP(BLACK)LOCKING SCREWADJUSTINGKNOBDIAL RINGBONNETSPINDLESPRINGOPERATIONThe Honeywell Braukmann DS05 Dial Set PressureRegulating Valve is a balanced, direct acting pressureregulating valve. The DS05 provides constantdownstream pressure regardless of varying inletpressures and downstream flow demands.The spring force holds the valve in the open position untildownstream pressure, sensed by a port, is sufficient topress on the underside of the diaphragm and close thevalve. As downstream pressure drops due to demand,the force on the diaphragm is reduced and the valveopens. Adjustment is made by manually turning theadjustment knob clockwise to increase the thespring force and require a higher downstream pressureto close the valve. Similarly, reducing the spring forcelowers the outlet set pressure. A factory-calibrated dial isbuilt into the adjustment mechanism to allow outletpressure (no flow) to be set without a gauge. A lockscrew maintains the setting. A black plastic cover isprovided for additional protection.Once the outlet pressure is set, the DS05 automaticallyregulates to maintain the downstream pressure.
