Lubrication of seals and threads
CAUTION
For product contact seals do not use conventional
greases and oils. Observe the safety information sheets
issued by the lubricant manufacturers.
• Grease the thread of the valve disk and all screws.
• Do not grease the V-ring.
• Apply a very light film of grease to all seals –
including the O-rings at the top and bottom of the
piston rod for the actuator.

Assembling
Mounting to The control
module T.VIS onto FDD
CAUTION
The permanent magnet on the switch bar (1) is fragile
and must therefore be protected against mechanical
impact stress.
The magnetic fields can delete data carriers and affect
or destroy mechanical components.
• Check that the switch bar (1) is firmly in place. If
needed, tighten using an Allen key at (1.1) or an open
spanner, size 13 at (1.2): tightening torque 2Nm (1.4
lbft).
• Pass the control module (B) over the valve stem (1)
and place it on to the actuator (A.1).
• Fix the clamps (15) by tightening the screws (39) at a
torque of 1 Nm (0.7 lbft).
• Align the pneumatic and electrical connections
according to the valve block configura-tion.
• Carry out commissioning, see operating instructions
of the control module T.VIS M-1 FDD.
