Installation
Risk of personal injury due to incorrect re-
moval of the anti-rotation xture under ten-
sion.
Once the actuator has been mounted on the
valve and the assembly is ready for use, the
clamps (301) of the anti-rotation xture on
the plug stem are under tension.
Î Follow the instructions in this document
during mounting or removal.
Î Do not loosen the screws (303) of the
anti-rotation xture while the force
generated by the supply air and/or the
actuator springs is transmitted to the
actuator stem and the stem (9).
Î First remove the actuator from the valve
or ensure it cannot transmit any forces to
the actuator stem before removing the
anti-rotation xture on the plug stem.
Depending on the version, SAMSON control
valves are either delivered with the actuator
already mounted on the valve or the valve
and actuator are delivered separately. When
delivered separately, the valve and actuator
must be assembled together on site.
Versions with V-port plug
To achieve the best ow conditions inside the
valve, the V-port plug must always be in-
stalled with the port that releases the ow
rst when the valve opens facing toward the
valve outlet. This is the largest of the three
V-shaped ports (see Fig.5-5).
Î Before mounting the actuator, determine
which V-shaped port is uncovered rst
when the plug is lifted out of the seat.
Î On mounting the actuator, make sure
that the V-shaped port uncovered rst
faces toward the valve outlet.
1x large V-port:
First to release the ow when the
plug is lifted out of the seat.
2x small V-ports

Versions with perforated plug
Only one hole is located near the seal facing
of perforated plugs with equal percentage
characteristic. Depending on the nominal
size, the hole pattern varies and is partly un-
symmetrical. The process medium in the
valve ows through the holes as soon as the
plug is lifted out of the seat. To achieve the
best ow conditions inside the valve, the per-
forated plug must always be installed with
the hole that releases the ow rst when the
valve opens facing toward the valve outlet
(see Fig.5-6).
Î Before mounting the actuator, check the
hole pattern of the perforated plug and
determine which hole is the closest to the
