DRE/DRD
To fit the DRD/DRE with a mounting bridge you will need:

a coupling aJ.
1. Align the mounting bridge so that its frame
elements face in the direction of the tubing and
the open side of the mounting bridge faces the
process valve.
2. Fasten the mounting bridge to the DRD/DRE.
Do not tighten the screws yet.
3. Guide the coupling aJ through the mounting
bridge and into the tetrahedral receptacle on
the underside of the DRD/DRE. Make sure that
the coupling sits in the receptacle without
being tilted.
4. Using the mounting bridge and coupling,
fasten the DRD/DRE to the connecting flange
of the process valve. Make sure here that the
square of the process valve sits in the coupling
without being tilted.
5. Tighten all the screws in diagonally opposite
sequence. Tightening torque è Technical
specifications.
6. Check that the DRD/DRE turns in the required
direction of rotation and whether the process
