Assembly Sequence In The Example Of A Double Seat Valve - Pentair SUDMO IntelliTop 2.0 Operating Instructions Manual

Installation
(shoulder screws M5), which engage in the middle groove of the hub flange (protection against pulling off).
The control head can radially slide into any position in 360° arc, seamlessly.
The hub flange and non ferromagnetic piston rod with the target which is used to record the position must comply
with the specifications with regard to material and stability - only specification-compliant attachment kits may be used.

(*) The fastening materials for target and piston rod, as well as the piston rod itself, may not be made of material
with very good electrical conductivity (e.g. copper, aluminum) or of ferromagnetic material.
• To ensure the proper function of the position measuring system, the axial deviation of the adapter must
be less than ± 0.1 mm to the spindle when mounted!
• Use Pentair Südmo adaptations only.
• Prior to assembling the control head onto the hub flange, lightly grease the O-rings with a silicone
grease (e.g. Paraliq GTE 703).
• The hood must be lead-sealed in the explosion-risk area to prevent the housing from being opened
without a tool! (Optionally the hood can also be locked with plastic self-cutting screws, see note to
"Fig. 5" on page 22.)

Mount the piston rod with the target on the process valve spindle. Observe reference dimensions!
→
Fasten the hub flange on the process valve.
During this, observe central alignment and sealing conditions!
→
Check the secure fit of the sealing rings (in the upper and lower grooves).
