1 Safety instructions and measures
Intended use
The SAMSON Type3273 Hand-operated Actuator is mounted on a valve and is intended for
the following activities in combination with a pneumatic actuator, e.g. SAMSON Type3271
or Type3277 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 dened conditions (e.g. thrust, travel,
actuator area). Therefore, operators must ensure that the side-mounted handwheel is only
used in applications that meet the specications used for sizing at the ordering stage. In case
operators intend to use the handwheel in other applications or conditions than specied,
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 dened 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

Safety instructions and measures
Qualications of operating personnel
The handwheel must be mounted, started up, serviced, and repaired by fully trained and
qualied personnel only; the accepted industry codes and practices are to be observed. Ac-
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 modications
Revisions, conversions or other modications 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 section6.1).
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.
EB 8312-2 EN 7
Safety instructions and measures
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions as
well as the referenced documents and observe the hazard statements, warning and caution
notes specied in them. Furthermore, the operating personnel must be familiar with the ap-
plicable health, safety and accident prevention regulations and comply with them.
Referenced documentation
The following documents apply in addition to these mounting and operating instructions:
−Mounting and operating instructions for mounted actuator, e.g. for SAMSON Type3271
and Type3277 Actuators:

uEB8310-3 (1400-60cm²) (Type3271 only)
uEB8310-4 (355cm²)
uEB8310-5 (175 and 750cm²)

1.1 Notes on possible severe personal injury
DANGER
!
The handwheel poses no hazard with possible severe personal injury.
ÎObserve hazard statements in the associated valve and actuator documentation.
8 EB 8312-2 EN
Safety instructions and measures
1.2 Notes on possible personal injury
WARNING
!
Crush hazard arising from moving parts.
The handwheel contains moving parts (actuator stem, threaded rod, plug stem, hand-
wheel), which can injure hands or ngers if inserted into it.
ÎDo not insert hands or ngers into the yoke while the valve is in operation.
ÎWhile working on the handwheel, disconnect and lock the pneumatic air supply as
well as the control signal.
ÎUse the locking bolt to lock the handwheel.
1.3 Notes on possible property damage
NOTICE
!
Risk of handwheel damage due to the use of unsuitable tools.
ÎTo turn the handwheel, do not use any additional tools, such as a lever or wrench.
Risk of handwheel damage due to the use of excessive force.
ÎDo not turn the handwheel in the end position any further by exerting force.
Risk of damage to control valve components due to excessively high or low tighten-
ing torques.
Observe the specied torques on tightening control valve components. Excessively
tightened torques lead to parts wearing out quicker. Parts that are not tightened far
enough may loosen.
ÎObserve the specied tightening torques (uAB0100).

Design and principle of operation
3 Design and principle of oper-
ation
The Type3273 Side-mounted Handwheel
with 30mm travel is suitable for mounting
on Series240, 250, 280, and 290 Valves or
on suitable interfaces together with the
Type3271 or Type3277 Pneumatic Actua-
tors with areas of 175 to 1400-60cm². 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.
