Regulators installed at circulating line take-offs or pumps are used to reduce main line pressure and maintain the desired fluid pressure to the spray gun, dispensing valve, or atomizing head. Before Installing the Fluid Regulator 1. Determine placement of the fluid regulator in system. 2. Install a ball valve for inlet and outlet of the regulator. 3. Install temporary plumbing between the ball valves. 4. Thoroughly flush the system to remove metal chips and other contaminants and to check for leaks. 4 306878 Installing the Fluid Regulator 1. Remove the temporary plumbing and install one regulator for each spray gun. A mounting stud, washers, and locknut are provided for mounting the regulator either from the bottom or side. 2. Put sealer on threaded connections, except on swivel unions as it interferes with the swivel action. 3. Connect the fluid supply line to the 3/8 npt(f) inlet of the fluid regulator. Connect the fluid line between the gun and the regulator’s 1/4 npt(f) outlet of choice. MAKE SURE that the direction of fluid flow agrees with the IN and OUT markings on the regulator body. 4. Flush and test the entire system.

Fluid under high pressure can be injected through the skin and cause serious injury. To reduce the risk of an injury from injection, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you: D are instructed to relieve the pressure, D stop spraying, D check or service any of the system equipment, D or install or clean the spray tip. 1. Lock the gun trigger safety. 2. Close the bleed-type master air valve (required in your system). 6. Open the drain valve (required in your system), having a container ready to catch the drainage. 7. Leave the drain valve open until you are ready to spray again. If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved after following the steps above, very slowly loosen the tip guard retaining nut or hose end coupling and relieve pressure gradually, then loosen completely. Now clear the tip or hose. Adjusting the Regulator The fluid pressure regulator controls pressure downstream from its outlet. To adjust the fluid regulator, first, back the knob out until there is no spring pressure. Then, turn the knob clockwise to increase pressure. NOTE: If you are using an accessory fluid pressure gauge, relieve the spray gun line when reducing pressure to ensure a correct gauge reading. 3. Unlock the gun trigger safety. Adjust the pump air pressure and the fluid regulator for the best spraying combination. In a circulating system, also adjust the back pressure valve. 4. Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve pressure. Record all the settings for future reference. The valve cylinder (7) has exterior markings (set points 1 to 8) for repeat settings. 5. Lock the gun trigger safety. 306878 7 Maintenance WARNING COMPONENT RUPTURE HAZARD To reduce the risk of serious bodily injury, including fluid injection or splashing in the eyes or on the skin, always follow the Pressure Relief Procedure on page 7 before adjusting, cleaning, repairing, or removing the regulator from the system. Cleaning When changing fluids or colors, the regulator should be disassembled and cleaned. Regular cleaning and inspection, and lubrication of the piston (15) and piston packing (10) are necessary to keep the fluid regulator working properly. 1. Relieve all the air and fluid pressure in the system. 2. Remove the regulator from the system. Never pressurize the system with the fluid regulator adjusting knob removed. 3. Disassemble the regulator, referring to the Parts Drawing on page 9. Clean and inspect all parts. Never completely remove the adjusting knob when system pressure is present. Flushing D Flush before changing colors, before fluid can dry in the equipment, at the end of the day, before storing, and before repairing equipment. D Flush at the lowest pressure possible. Check connectors for leaks and tighten as necessary. CAUTION Use special care when handling the hard carbide portions of the piston (13) and seat (12). Damage will cause poor operation and leakage. Repairing D Flush with a fluid that is compatible with the fluid being dispensed and the equipment wetted parts. Normally, only the ball support (21), seat (20) and piston packing (10) will ever need replacement. Repair Kit 220139 is available to replace these parts. See page 9. 1. Record the pressure adjustment setting of the regulator before flushing. 1. Lubricate the piston packing (10), piston (15), and spring locater (11) with lithium base grease. 2. Shut off the pump and relieve fluid pressure in the system by triggering the gun and opening the back pressure valve or other bypass valve. 2. Place the washer (19) over the pointed end of the piston (15). 3. Never exceed the maximum working pressure of the lowest rated system component. 3. Place the packing (10), with its lips facing down, over the pointed end of the piston (15) and against the washer (19). 4. Open the fluid regulator by turning the adjusting knob (6) fully clockwise. 4. Insert the piston (15) into the bottom of the cylinder (7) and gently work it into place. 5. Supply solvent to the system. Set pump to the lowest possible pressure, and start pump. 5. Reassemble the remaining parts in reverse order of disassembly. Torque the valve seat (20) into the housing to 175 to 200 in-lb (20 to 22 NSm). Over tightening could break off the hex portion of the seat. 6. Flush until thoroughly clean. 7. Adjust the fluid regulator to return to the desired fluid pressure setting. NOTE: Do not allow paint or solvent to set in the system for a long time. Fluid could dry on the piston, causing leakage at the piston packing. If leakage occurs, disassemble and clean the regulator. 8 306878 Parts 16 18 6 8n 13 9 8 11 5* 7 20* Torque to 175 to 200 in-lb (20 to 22 NSm) 17 *10 19 3 2 Install with lips down Use Loctiter Grade TL242 on threads 14 12 *15 Torque to 55 to 65 in-lb (6.3 to 7.3 NSm) 1 Use Loctiter Grade 601 on threads 26 1 Mounting Parts 4 Model 206661, Series G Model 217576, Series D Includes items 1–20 Includes items 1–26 REF NO.
