5.5 Installing sensor to process coupling
1. Separate sealing bushing (A) and sealing nut (B from each other. Make sure that
the O-ring (C) is properly installed in the sealing bushing (A). Push the sealing bush-
ing towards the probe tip until it stops at the lock ring.
2. Tighten the sealing bushing to the ball valve. Do not over-tighten!
3. Install the locking ring (D). This ring
ensures that the assembly is opened in
the correct order: the sealing nut must be
opened first before the sealing bushing
can be unscrewed. The locking ring must
be on the flat tool surface of the ball
valve, as shown in the photo.
