All the fluid passages are in stainless steel (303), membrane in
PTFE, cover in aluminum nickel treatment for manual model or anodized for remote air control.
The regulators HGB-609 are equipped with stainless steel tee and riser tube and a manometer. The tightness of these connections ought to be perfect so to protect the manometer.
See drawings on « Accessories ».
IMPORTANT: These regulators may be used with most common coating and finishing materials. However, there are not designed for use with highly corrosive materials which have such characteristics, it must be expected that frequent and thorough cleaning will be required and/or the necessity for replacement of parts will be increased.
INSTALLATION
The regulators must be fitted in horizontal position to remove heavy fluid particle deposit. The riser tube for manometer must be in vertical position. The manometer will be protected by air staying into the top of the riser tube.
A good sealing ought to be done on the connectors so to remove any air leakage to protect the manometer.
Connect the fluid supply line, coming from pump or pressure feed tank, under the regulator at the ¼’’ BSP or
3/8’’ NPS/BSP universal (See on page 11 depend of version used).

4. Unscrew the fluid inlet connector remove the spring and the ball valve. Clean all the parts and the gasket inside the valve body. If the gasket is damaged replace it. Please follow the instruction described on page 6. If the gasket is ok put thread locking compound (loctite 222) on the connector thread and tighten to a maximum torque of 6.4Nm.
Periodically clean exterior of regulator with solvent soaked rag.
REPLACEMENT OF PARTS
OPERATION
Relieve the line pressure before servicing for pneumatic model
(HGB-510). For manual model HGB-509 & 609, Relieve spring forces by unscrewing the adjusting screw rep 4 at the maximum
(FIG A).

For models HGB-510-R1, R2 or R4
TO REPLACE DIAPHRAGM
The fluid pressure regulation is adjusted by remote air pressure regulator, for that connect Rilsan tube on the top connector on cover. To flush the regulator, connect air tube on the side connector
(R1/R2/R4) and set the air pressure to full open the valve regulator.
It’s useful to fit the air regulator close to the fluid regulator to obtain the accurate regulation at a low fluid flow. If it’s not the case, you can obtain this accurate regulation in piercing the Rilsan tube with sewing needle near of the connector to create a small air leakage.
1. Remove the 6 hex. head cap screws.
2. The diaphragm is sold complete with its washer and its fluid flow plastic deflector. These parts could be not separated, if diaphragm or the deflector is damaged replace it.
3. Install the new diaphragm kit into the regulator body.
4. Put the cover on the regulator and screw the 6 screws at 7.5 to
8 mN.
To flush the fluid line with solvent, connect the flushing air command to the right connector on the side of the regulator.
5. For the pneumatic model HGB510, reassemble all the parts in the right order and position. It’s recommended before to set the regulator that the two diaphragms work about 10 time so to be in full condition, this operation could be done in using the connector Rep 8 and pressurize the flushing cavity at 4 bar.
DO NOT EXCEED THE FLUSHING AIR COMMAND MORE
THAN 1 BAR OVER THE SOLVENT PRESSURE.
TO SERVICE VALVE ASSEMBLY
Note: To come back at the initial set up after cleaning operation, purge the air line so to have no air pressure on intermediary chamber. This intermediary chamber can be used as a safe area if the membrane brakes and fluid leakage goes through the air line.
“Perlast D shape” seat and Ball valve.
1. Unscrew the fluid inlet valve and connector rep 16 from the regulator body.
To know and differentiate what is your regulator model, an arrow is marked above the cover which is either in direction of the flushing air inlet connector for the R1 model or in direction of the
1/ 4 or 1/ 2 printed on the intermediary plate. Take care during the re assembling operation after maintenance to fit the cover in the right place corresponding to the model of regulator used.
PREVENTIVE MAINTENANCE
2. Clean and check the valve, if the parts are damaged, replace the parts in using the valve kit.
3. Fit the washer in the right position small dimension in front of the “D” gasket, Screw the valve body on the regulator body with a sealing compound “loctite 270” on the third thread and tight at maximum torque 12Nm, Do not exceed this torque, over torque will damaged the regulator body.
Periodic cleaning of regulator with a solvent compatible with the material being used is recommended. To clean material from the regulated material line and the regulator, these steps should be followed:
4. Wait a few minutes for the loctite to dry and fit the ball valve and the spring
5. Clean the thread on the fluid inlet connector, use a thread locking compound like Loctite 222.
1. Relieve supply line pressure.
6. Apply a maximum torque 6.4Nm.
2. Put the regulator in flushing position (See “Operation”). This holds the valve off its seat.
3. Blow material back through the regulated line by introducing air pressure into the line down stream from the regulator. With spray gun attached this can be done by loosening air cap ring on gun, holding a rag over air cap and pulling gun trigger. This
