Preventive Maintenance; Replacement Of Parts - Binks HGB-509 Series Operator's Manual

  PREVENTIVE MAINTENANCE
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 :
1. Relieve supply line pressure.
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 forces air in a reverse
path through spray gun and air forces material back through regulated material line.
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
Note : 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).
TO REPLACE DIAPHRAGM
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.
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.
TO SERVICE VALVE ASSEMBLY
" Perlast D shape" seat and Ball valve.
1. Unscrew the fluid inlet valve and connector rep 16 from the regulator body.
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.
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.
6. Apply a maximum torque 6.4Nm.
