5.5 Installing a volume
restriction
We recommend using a volume restriction
− For linear actuators with a transit time
<1 s (e.g. with an actuator area smaller
than 240 cm²),
− For rotary actuators with a volume of less
than 300 cm³.
Volume restriction in the connection block
(direct attachment). See Fig. 5-6.

1. Apply a thin film of lubricant to the
O-ring at the signal pressure output.
2. Carefully push and turn the volume re-
striction (1) (e.g. using a hex wrench) in-
to the opening (tube) of the signal pres-
sure output at the connection block as far
as it will go.
3. Place the connection block (2) against
the positioner and the actuator yoke and
fasten using the screw.

1. Insert the volume restriction (1) with
O-ring at the signal pressure output of
the connecting plate (3)/pressure gauge
