4.4.5. FILLING VALVE
To protect filling valve against contamination a sintered
metal filter is screwed in the filling valve body.
-
Unscrew pressure gauge (3, Fig. 22) from filling valve
body (1).
- Screw off sintered metal filter (2) with a suitable screw
driver.
- To clean filter element, the best method is to use hot
soapy water and to blow dry with compressed air.
Replace if heavily soiled.
- Screw in filter element,.
- Seal pressure gauge with PTFE tape or Loctite 243 and
screw in tight to desired position.

4.4.6. PRESSURE MAINTAINING VALVE
DESCRIPTION
A pressure maintaining valve (1, Fig. 23) is mounted on the
filter head of the filter system P11.
It ensures that pressure is built up in the filter even from the
start of delivery, thus achieving a constant, optimum filtra­
tion. It will also guarantee proper working conditions for
the final stage cylinder.
The pressure maintaining valve is adjusted to 150
±
10 bar
(2,175 psi) .

MAINTENANCE
The pressure maintaining valve (Fig. 23) is adjusted at the
factory to the required pressure and normally does not re­
quire regular maintenance.
4.4.7. SAFETY VALVES
DESCRIPTION
All three compressor stages are protected by safety valves
as follows
1st stage 9 bar (130 psi)
2nd stage 80 bar (1,160 psi)
The safety valve for protection of the last stage is mounted
on top of the filter system P21 and is adjusted to the operat­
ing pressure of the unit (see chapter 1, Technical Data),
225
bar (3,200 psi) for the standard units, 330 bar (4,700 psi)
for models -H or -HU . All safety valves are sealed at the fac­
tory.
If one of the intermediate pressure safety valves blows off,
the valves in the next stage are not closing properly, afford­
ing valve check. The cause of the trouble is usually the inlet
valve of the next stage. See also chapter 4.4.9.
MAINTENANCE
Checking function
The final pressure safety valve has to be checked regularly.
For this purpose the safety valve can be vented manually.
Turn knob on top of the valve anticlockwise until valve
blows off (Fig. 24).
This just ensures that the valve is functional and will release
pressure in case of a malfunction. To check the blow-off
pressure value refer to ”Blow-off pressure check”.
