Safety instructions and measures

1 Safety instructions and measures
Intended use
The SAMSON Type 3273 Hand-operated Actuator mounted on a valve is intended for thefollowing activities:− To manually move the valve to the closed or open position− To operate a mounted valve without pneumatic or electric actuator
The hand-operated actuator is designed to operate under exactly defined conditions (e.g.
thrust, travel). Therefore, operators must ensure that the hand-operated actuator is only usedin operating conditions that meet the specifications used for sizing the hand-operated actuator at the ordering stage. In case operators intend to use the hand-operated actuator in applications or conditions other than those 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 hand-operated actuator is not suitable for the following applications:− 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
Qualifications of operating personnel
The hand-operated actuator must be mounted, started up, serviced and repaired by fully
trained and qualified personnel only; the accepted industry codes and practices must be observed. According to these mounting and operating instructions, trained personnel refers toindividuals 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.

hazard statements, warnings and caution notes in these mounting and operating instructions.
Responsibilities of the operator
Operators are responsible for proper use 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, operators must ensure that operating personnel or third parties are not exposed toany danger.
Responsibilities of operating personnel
Operating personnel must read and understand these mounting and operating instructions aswell as the referenced documents and observe the specified hazard statements, warnings
and caution notes. Furthermore, operating personnel must be familiar with the applicablehealth, safety and accident prevention regulations and comply with them.

Safety instructions and measures

1.1 Notes on possible severe personal injury! DANGER
The hand-operated actuator poses no hazard with possible severe personal injury.
Î Observe hazard statements in the associated valve documentation.

1.2 Notes on possible personal injury! WARNING
Crush hazard arising from moving parts.
The hand-operated actuator contains moving parts (actuator stem, plug stem, handwheel), which can injure hands or fingers if inserted into it.
Î Do not insert hands or finger into the yoke while the valve is in operation.
Î Use the locking bolt to lock the handwheel.
Exposure to hazardous substances poses a serious risk to health.
Certain lubricants and cleaning agents are classified as hazardous substances. These
substances have a special label and a material safety data sheet (MSDS) issued by the
manufacturer.

The Type 3273 Hand-operated Actuator is aspindle actuator equipped with a non-rising
handwheel. The hand-operated actuator canbe used without a mounted pneumatic orelectric actuator to position SAMSON Series 240, 250 and 290 Valves. A locking
bolt (17) locks the hand-operated actuator toprevent accidental adjustment of the valve
travel.

performed only by personnel appropriately
qualified to carry out such tasks.
! NOTICE
Risk of damage to control valve components due to over- or under-torquing.
Observe the specified torques when tightening control valve components. Excessive
tightening torques lead to parts wearing out
more quickly. Parts that are not tightened far
enough may loosen.
Î Observe the specified tightening torques(u AB 0100).
! NOTICE
Risk of damage to control valve components due to the use of unsuitable tools.
Certain tools are required to work on thecontrol valve.
Î Only use tools approved by SAMSON(u AB 0100).
! NOTICE
Risk of damage to control valve components due to the use of unsuitable lubricants.
The lubricants to be used depend on thematerial of the control valve. Unsuitablelubricants may corrode and damage
surfaces.
Î Only use lubricants approved by
SAMSON (u AB 0100).

14! NOTICE
Risk of malfunction due to different travels.
Î Make sure that the travels of thehand-operated actuator and valve
match. If in doubt, contact our after-sales
service.

5.1 Preparation for installation
Proceed as follows:Î Check the hand-operated actuator fordamage.
Î Check whether the hand-operated actuator (model, travel, thrust and handwheel
diameter) fits the actuator and valve.
If the valve and hand-operated actuator are
delivered separately, assemble the components as described in the following chapter.

5.2 Mounting the hand-operated actuator onto thevalve
1. Unscrew the lock nut and stem connector
nut from the plug stem of the valve andthread them downward.
2. Firmly press the plug together with theplug stem into the valve seat.
3. Remove the stem connector clamps(26/27) and slotted nut (9) from thehand-operated actuator.
4. Slide the slotted nut (9) over the valve's
plug stem.

EB 8312-3 EN

Start-up

5. Place the hand-operated actuator on theyoke of the valve. Fasten tight with slotted nut (9).
6. Turn the handwheel to adjust the dimension H3 (see Fig. 5) for the actuator stem
(8).
7. Thread the stem connector nut on theplug stem upward until the contact surfaces of the stem connector nut and theactuator stem (8) touch.
8. Use the lock nut to lock the plug stem
against the stem connector nut.
9. Connect the actuator stem and plug stem
