First stage valve:
I . Connect the regulator to the test box.
2. Connect the LP gauge hose to one of the low
pressure outlets.
3. Open the LP valve (= 20 bar),.
4. Set the secondary pressure at 10 bar, and
intermittently purge the second stage by means
of the button. NOTE that the second stage valve
must be fully tight during this test. When the
pressure gauge needle stops at the preset
pressure, a maximum rise in pressure of I bar is
acceptable. If the needle continues to move to a
higher pressure reading there is a fault in the seal
between the valve seat and the piston or the
O-ring.
5. Close the LP valve, and open the HP valve
(=200/3OObar). Purge intermittently with the
purge button, check the tightness, and adjust the
pressure to 8,5-9 bar.
Second stage valve: Tightness test of the low
pressure valve and the servo valve.
1. Push the servovalve on the low pressure valve
carefully, and purge a few times. Immerse the
valve in a water tank and make sure the valve is
absolutely air tight.
Checking and adjustment of the inhalation
resistance:
1. Connect the oval connecting pipe of the inha-
lation resistance gauge to the mouth-piece on the
regulator.
2. Test-breath. Check the reading of the gauge
needle, which should rise to 38-44 mmvp when
the valve is opening.
3. Adjustment:
Remove the cover and the diaphragm.
Hold the diaphragm center on the center part and
push an Allen wrench No. 8510 (1,27 mm) in the
adjustment screw.
If the resistance is too low, turn the screw
anticlockwise.
If the resistance is too high, turn the screw
clockwise.
4. Install the diaphragm with the adjustment screw
to the right position and the cover. Test again
from pos. 1.
Checking the purge button:
1. Press the purge button. The second stage valve
should now provide a generous supply of air.
2. Cover the mouth-piece and press the purge
button. The second stage valve should now
supply a reduced air flow.
