1 Safety instructions and measures
Intended use
The SAMSON Type3273 Hand-operated Actuator is mounted on a valve and is intended for
the following activities in combination with a pneumatic actuator, e.g. SAMSON Type3271
or Type3277 Actuator:
−To manually move the valve to the closed or open position for maintenance or repair
work, e.g. to exchange the actuator.
−To manually move the valve upon air supply failure
−To keep the fail-safe action of the pneumatic actuator also during maintenance and re-
pair work on the actuator
−Special version: to operate a mounted valve without pneumatic actuator
The side-mounted handwheel is not suitable to perform control tasks. The side-mounted
handwheel is designed to operate under exactly dened conditions (e.g. thrust, travel,
actuator area). Therefore, operators must ensure that the side-mounted handwheel is only
used in applications that meet the specications used for sizing at the ordering stage. In case
operators intend to use the handwheel in other applications or conditions than specied,
contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the de-
vice for its intended purpose or for damage caused by external forces or any other external
factors.
ÎRefer to the technical data and nameplate for limits and elds of application as well as
possible uses.
Reasonably foreseeable misuse
The handwheel is not suitable for the following applications:
−To limit the valve travel
−To control the ow rate through the mounted valve (on/off only)
−Use outside the limits dened during sizing and in the technical data
Furthermore, the following activities do not comply with the intended use:
−Use of non-original spare parts
−Performing service and repair work not described in these instructions

cording to these mounting and operating instructions, trained personnel refers to individuals
who are able to judge the work they are assigned to and recognize possible hazards due to
their specialized training, their knowledge and experience as well as their knowledge of the
applicable standards.
Personal protective equipment
We recommend wearing the following protective equipment:
−Safety gloves due to the moving parts (actuator stem, threaded rod, plug stem, hand-
wheel)
ÎCheck with the plant operator for details on further protective equipment.
Revisions and other modications
Revisions, conversions or other modications to the product are not authorized by SAMSON.
They are performed at the user's own risk and may lead to safety hazards, for example. Fur-
thermore, the product may no longer meet the requirements for its intended use.
Safety devices
The side-mounted handwheel is locked by a locking bolt, which locks the gear, to prevent ac-
cidental adjustment of the valve travel (see Fig.7 and section6.1).
Warning against residual hazards
To avoid personal injury or property damage, plant operators and operating personnel must
prevent hazards that could be caused in the handwheel by the signal pressure or moving
parts by taking appropriate precautions. They must observe all hazard statements, warning
and caution notes in these mounting and operating instructions, especially for installation,
start-up, and service work.
Responsibilities of the operator
The operator is responsible for proper operation and compliance with the safety regulations.
Operators are obliged to provide these mounting and operating instructions as well as the
referenced documents to the operating personnel and to instruct them in proper operation.
Furthermore, the operator must ensure that operating personnel or third persons are not ex-
posed to any danger.

Design and principle of operation
3 Design and principle of oper-
ation
The Type3273 Side-mounted Handwheel
with 30mm travel is suitable for mounting
on Series240, 250, 280, and 290 Valves or
on suitable interfaces together with the
Type3271 or Type3277 Pneumatic Actua-
tors with areas of 175 to 1400-60cm². A
special version of the side-mounted hand-
wheel can also be used to move the valve on
which a pneumatic actuator is not mounted.
The side-mounted handwheel is mounted be-
tween the valve and actuator. The handwheel
can remain mounted on the valve during
maintenance and repair work or while ex-
changing the pneumatic actuator. The hand-
wheel can be used in this case to move the
valve manually to its closed or open position.
The handwheel can be used to move the
valve manually opposing the spring force of
the pneumatic actuator upon air supply fail-
ure.
The worm shaft unit, consisting of the worm
shaft and worm-geared wheel, is driven over
the handwheel. The spindle nut transfers the
rotary motion to the threaded rod, which
moves the valve. Depending on the direction
of rotation and mounted valve, the threaded
rod extends or retracts.

Mounting and start-up
5 Mounting and start-up
−The actuator must be removed rst before
mounting the handwheel if the valve and
actuator have already been assembled.
See instructions on how to remove the
actuator in the associated actuator
documentation.
−In case, the valve, actuator, and hand-
wheel are delivered separately, assemble
components as described in following.
−See associated valve and actuator
documentation for additional mounting
instructions.
Risk of damage to control valve components
due to excessively high or low tightening
torques.
Observe the specied torques on tightening
control valve components. Excessively tight-
ened torques lead to parts wearing out
quicker. Parts that are not tightened far
enough may loosen.
Observe the specied tightening torques
(uAB0100).
Risk of damage to control valve components
due to the use of unsuitable tools.
Certain tools are required to work on the
control valve.
Only use tools approved by SAMSON
(uAB0100).
Risk of damage to control valve components
due to the use of unsuitable lubricants.
The lubricants to be used depend on the ma-
terial of the control valve. Unsuitable lubri-
cants may corrode and damage the valve
surface.
Only use lubricants approved by SAMSON
(uAB0100).
Risk of malfunction due to different travels.
Make sure that the travels of the actuator,
handwheel, and valve match. If necessary,
contact SAMSON's After-sales Service de-
partment.
Risk of control valve damage due to the in-
correct mounting.
Versions with anti-rotation xture at the plug
stem must only be mounted by SAMSON's

ready-mounted stem connector nut (G71)
on the threaded rod touches the stem
connector nut (G5) on the valve.
7. Connect the threaded rod and plug stem
using the stem connector clamps
(G26/27). Tighten the hex screws (G29).
Observe tightening torques.
8. Optionally, a protective bellows (G69)
can be mounted around the plug stem on
the valve side.
5.2 Mounting the actuator onto
the handwheel
The handwheel and actuator are assembled
with special attention paid to the actuator's
bench range and direction of action. These
details are specied on the actuator name-
plate (see the associated actuator documen-
tation).
1. Move the handwheel to the neutral posi-
tion (see section6.1).
2. Remove the clamps of the stem connector
(A26/27) and the ring nut (A8) from the
actuator.
3. Apply a suitable lubricant to the thread-
ed nipple on the top bonnet (G60).
4. In the "actuator stem extends" version:
apply a signal pressure to the connection
on the bottom diaphragm chamber to
completely retract the actuator stem (A7).
In the "actuator stem retracts" version:
vent the actuator to retract the actuator
stem (A7) completely.
