Press valve stem towards main body; cap (130) and
a suitable tool (screw driver) can be used as a lever.
Exert pressure SLOWLY and wait until pressure
compensation is effected. Press valve stem
through until stop and let it go back smoothly:
The SAV is open and will re-engage.
When using the tripping valve RMG 919-3 instead
of a breathing line, make sure to screw out the
locking screw (100) prior to re-engagement
operation.

Screw out locking cap, turn it round, screw it on
to valve stem and turn slowly towards body;
the pressure compensation valve will respond.
Pull locking cap until stop and let it go back
smoothly: The SAV is open and will re-
engage.
In order to ensure perfectly reliable SAV-release
performance after re-opening, it is indispensable
to screw the locking cap (201) back into its normal
position.
• Tripping tests
In order to avoid the risk of mechanical damages tripping tests should be effected only after the measuring unit will
have been mounted into the main valve body.
