6.1 Adjusting the restrictor
manually (only K
version with restrictor
plate)
Restrictor plates with lock nut
Î Remove the cover protecting the lock nut
on the beveled corner of the restrictor
plate.
Î Undo the lock nut.
Î Adjust the actuating times:
− Turn the restrictor spindle clockwise
to reduce the cross-sectional area of
flow (slows the stroking speed).
− Turn the restrictor spindle counter-
clockwise to increase the cross-sec-
tional area of flow (increases the
stroking speed).

Î Adjust the actuating times:
− Turn the adjustment screw clockwise
to reduce the cross-sectional area of
flow (slows the stroking speed).
− Turn the adjustment screw counter-
clockwise to increase the cross-sec-
tional area of flow (increases the
stroking speed).
Î Push the safety plate back into its origi-
nal position (concealing the adjustment
screw). Fasten it in place with the two re-
taining screws.
Note
The construction of the restrictor plates suit-
able for SIL applications ensures that the
cross-sectional area of flow cannot be com-
pletely closed.
