1 Safety instructions and measures
Intended use
The SAMSON Type 3273 Hand-operated Handwheel is mounted on a valve and is intended
for the following activities in combination with a pneumatic actuator (e.g. SAMSONType 3271 or Type 3277 Actuator):− To manually move the valve to the closed or open position for maintenance or repair
work (e.g. while exchanging the actuator)− To manually move the valve upon air supply failure− To hold the valve in the fail-safe position while performing maintenance and repair workon the pneumatic actuator− Special version: to operate a mounted valve without pneumatic actuator
The side-mounted handwheel in combination with a pneumatic actuator is not suitable toperform control tasks. The side-mounted handwheel is designed to operate under exactly defined conditions (e.g. thrust, travel, actuator area). Therefore, operators must ensure that theside-mounted handwheel is only used in operating conditions that meet the specifications
used for sizing at the ordering stage. In case operators intend to use the handwheel in otherapplications or conditions than specified, contact SAMSON.
SAMSON does not assume any liability for damage resulting from the failure to use the device for its intended purpose or for damage caused by external forces or any other external
factors.
Î Refer to the technical data and nameplate for limits and fields of application as well as
possible uses.
Reasonably foreseeable misuse
The handwheel is not suitable for the following applications:− Limiting the valve travel− Controlling the flow rate through the valve (except for the special version without pneumatic actuator)− Use outside the limits defined during sizing and by 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

3 Design and principle of operation
The Type 3273 Side-mounted Handwheelwith 30 mm travel is suitable for mounting
on SAMSON Series 240, 250, 280 and
290 Valves or on suitable interfaces together
with the Type 3271 or Type 3277 Pneumatic
Actuators with areas of 175 to 140060 cm². A special version of the side-mounted handwheel can also be used to move thevalve when a pneumatic actuator is notmounted on it.
The side-mounted handwheel is mounted between 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 handwheel can be used in this case to move thevalve manually to its closed or open position.
The handwheel can be used to move thevalve manually opposing the spring force ofthe pneumatic actuator upon signal or supply air failure.
The worm shaft unit, consisting of the worm
shaft and worm-geared wheel, is driven overthe handwheel. The spindle nut transfers therotary motion to the threaded rod, whichmoves the valve. Depending on the directionof rotation and mounted valve, the threadedrod extends or retracts.

7 Operation
The handwheel is ready for use when mounting and start-up have been completed.
! WARNING
Crush hazard arising from moving parts(actuator stem, threaded rod, plug stem,
handwheel).
Î Do not insert hands or finger into theyoke while the valve is in operation.
! NOTICE
Operation disturbed by a blocked actuator
stem, threaded rod or plug stem.
Î Do not impede the movement of the actuator stem, threaded rod or plug stem byinserting objects into their path.

The valve position is adjusted by the handwheel in manual operation. It can be adjusted either when the supply air is still appliedor has failed or when no pneumatic actuator
is mounted onto the valve (special version).

7.1 Working in automatic operation
In automatic operation, the valve is movedby the pneumatic signal. The side-mounted
handwheel is locked by the locking bolt toprevent accidental adjustment of the valve
travel.
In automatic operation, the handwheel is in
the neutral position. The groove at the top
end of the threaded rod must be alignedwith the top of the guide tube (see Fig. 10).
