The safety valves are adjusted to the corresponding pres
sure and sealed at the factory.
The safety valve for protection of the last stage is adjusted
according to order, see 1.3, Technical Data, but maximally
to the values given above.
8. PRESSURE GAUGES
The pressure in the final compressor stage can be mon
itored by means of the B-CONTROL display. See chapter
11. Pressure gauges in the instrument panel are optional ex
tras for all Verticus 5 units. If provided, the gauges should
indicate the correct pressures during operation.
8.1. INTERMEDIATE PRESSURE GAUGES
The correct values are given in chapter A-13.1., Technical
Data.
8.2. FINAL PRESSURE GAUGE
The final pressure gauge shows a mark indicating the max
imum operating pressure.

8.3. OIL PRESSURE GAUGE
Correct oil pressure indication should read approx. 4.5 bar
(3 to 6 bar) .
If not, check the lube oil circuit or adjust the oil pressure. See
chapter D-2.
For oil pressure monitoring, see chapter A-11.
9. VALVES
The valve heads of the individual stages form the top part
of the cylinders. The intake and pressure valves are fitted in
side the valve heads.
Note that the valves are operated by the flow of the me
dium. On the suction stroke, the intake valves open and the
medium flows into the cylinders. At the start of the com
pression stroke the intake valve closes and the medium
opens the pressure valve, Fig. 20.
Intake and pressure valve of the 1st stage is a combined
plate valve under the valve head (Fig. 21). Different valve
types are used as shown.
