1 Safety instructions and measures

Intended use
The SAMSON Type3349 Angle Valve in combination with an actuator (e.g. Type3271, Type3277 or Type3379 Pneumatic Actuator) is designed to regulate the ow rate, pressure or temperature of liquids, gases or vapors. The angle valve is suitable for use in aseptic ap­plications (e.g. in the pharmaceutical and food industries).
The valve with its actuator is designed to operate under exactly dened conditions (e.g. operating pressure, process medium, temperature). Therefore, operators must ensure that the control valve is only used in applications that meet the specications used for sizing the valve at the ordering stage. In case operators intend to use the control valve 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 valve 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 elds of application as well as
possible uses.
Reasonably foreseeable misuse
The control valve is not suitable for the following applications:
− Use outside the limits dened during sizing and in the technical data
− Use outside the limits dened by the valve accessories mounted on the control valve
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
Qualications of operating personnel
The control valve must be mounted, started up, serviced, and repaired by fully trained and qualied personnel only; the accepted industry codes and practices are to be observed. According 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.
EB 8048-2/-3 EN 5
Safety instructions and measures
Personal protective equipment
We recommend wearing the following protective equipment depending on the process medi­um:
− Protective clothing, gloves, and eyewear in applications with hot, cold, and/or corrosive media
− Wear hearing protection when working near the valve.
Î Check 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. Fur­thermore, the product may no longer meet the requirements for its intended use.
Safety features
Upon supply air or control signal failure, the valve moves to its fail-safe position (see sec­tion3.1). The fail-safe action of the actuator is the same as its direction of action and is spec­ied on the nameplate of SAMSON actuators (see actuator documentation).
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 control valve by the process medium, the operat­ing pressure, the signal pressure or by 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 exposed to any danger.
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 specied in them. Furthermore, the operating personnel must be familiar with the ap­plicable health, safety and accident prevention regulations and comply with them.

Safety instructions and measures
Referenced standards and regulations
The control valves meet the requirements in the Regulation (EC) No.1935/2004 for materi­als and articles intended to come into contact with food
The control valves comply with the requirements of the European Pressure Equipment Directive 2014/68/EU. This declaration of conformity is included in the Appendix of these instructions (see section10.2).
According to the ignition risk assessment performed in accordance with EN13463-1:2009, section 5.2, the non-electrical control valves do not have their own potential ignition source even in the rare incident of an operating fault. As a result, they do not fall within the scope of Directive 2014/34/EU.
Î For connection to the equipotential bonding system, observe the requirements specied in
section 6.4 of EN60079-14 (VDE0165 Part 1).

Safety instructions and measures

1.2 Notes on possible personal injury

!
WARNING
Crush hazard arising from moving parts.
The Type3349-1 or Type3349-7 Pneumatic Control Valve contains moving parts (actuator and plug stems), which can injure hands or ngers if inserted into the valve.
Î Do not insert hands or ngers into the yoke while the valve is in operation. Î While working on the control valve, disconnect and lock the pneumatic air supply as
well as the control signal.
Risk of personal injury when the actuator vents.
While the valve is operating, the actuator may vent during closed-loop control or when the valve opens or closes.
Î Install the control valve in such a way that the actuator does not vent at eye level. Î Use suitable silencers and vent plugs. Î Wear eye protection when working in close proximity to the control valve.
Risk of personal injury due to preloaded springs.
Valves in combination with pneumatic actuators with preloaded springs are under ten­sion. These control valves with SAMSON pneumatic actuators can be identied by the long bolts protruding from the bottom of the actuator.
Î Before starting any work on the actuator, relieve the compression from the preload-
ed springs (see associated actuator documentation).
Risk of personal injury due to residual process medium in the valve.
While working on the valve, residual process medium can escape and, depending on its properties, may lead to personal injury, e.g. (chemical) burns.
Î If possible, drain the process medium from all the plant sections concerned and the
valve.
Î Wear protective clothing, safety gloves, and eyewear.

!
WARNING
Risk of burn injuries due to hot or cold components and pipelines.
Depending on the process medium, valve components, and pipelines may get very hot or cold and cause burn injuries.
Î Allow components and pipelines to cool down or heat up. Î Wear protective clothing and safety gloves.

1.3 Notes on possible property damage

!
NOTICE
Risk of contamination of the process medium through the use of unsuitable lubricant and/or contaminated tools and components.
Î Keep the valve and the tools used free from solvents and grease. Î Make sure that only suitable lubricants are used.
Risk of valve damage due to contamination (e.g. solid particles) in the pipeline.
The plant operator is responsible for cleaning the pipelines in the plant.
Î Flush the pipelines before start-up. Î Observe the maximum permissible pressure for valve and plant.
Risk of valve damage due to unsuitable medium properties.
The valve is designed for a process medium with dened properties.
Î Only use the process medium specied for sizing the valve.
Risk of leakage and valve damage due to excessively high or low tightening torques.
Observe the specied torques on tightening control valve components. Excessively tight­ened torques lead to parts wearing out quicker. Parts that are too loose may cause leak­age.
Î Observe the specied tightening torques (uAB0100).
Risk of valve damage due to the use of unsuitable tools.
Certain tools are required to work on the valve.
Î Only use tools approved by SAMSON (uAB0100).

Design and principle of operation

3 Design and principle of oper-
ation
The Type3349 Angle Valve is preferably combined with a SAMSON Type3271 or Type3277 Pneumatic Actuator (see Fig.3) as well as the Type3379 Pneumatic Actuator (see Fig.4). The valve comes with welding ends as standard. The valve is suitable for aseptic applications and is designed without any cavities.
The process medium ows through the valve in the ow-to-close direction as indicated by the arrow. The position of the valve plug de­termines the ow rate across the cross-sec­tional area of ow released between plug and lathed seat.
In the standard version, the plug stem is sealed by the USP-VI diaphragm. In the spe­cial version, an additional backup packing is used (see Fig.5). The test connection allows the diaphragm to be monitored for leakage.
In the version with backup packing, the test connection is sealed by a stopper. The stop­per must be replaced with a suitable leakage indicator (e.g. a contact pressure gauge, an outlet to an open vessel or an inspection glass) when the valve is installed. The test connection of valves without a backup pack­ing is tted with a pipe elbow to allow the safe drainage of any medium that escapes.
When combined with the Type3271 or Type3277 Actuator, the actuator stem and plug stem are connected using stem connec­tor clamps (A26/27). When combined with the Type3379 Actuator, the actuator stem and plug stem are screwed together.

3.1 Fail-safe positions

The fail-safe position depends on the mount­ed actuator. Depending on how the com­pression springs are arranged in the pneu­matic actuator, the valve has two different fail-safe positions:
Actuator stem extends (FA)
When the signal pressure is reduced or the air supply fails, the springs move the actua­tor stem downward and close the valve. The valve opens when the signal pressure is in­creased enough to overcome the force exert­ed by the springs.
Actuator stem retracts (FE)
When the signal pressure is reduced or the air supply fails, the springs move the actua­tor stem upwards and open the valve. The valve closes when the signal pressure is in­creased enough to overcome the force exert­ed by the springs.
Tip
The direction of action of the Type3271 and Type3277 Pneumatic Actuator can be re­versed, if required. Refer to the mounting and operating instructions of the pneumatic actuator:

Vent plug
Vent plugs are screwed into the exhaust air ports of pneumatic and electropneumatic de­vices. They ensure that any exhaust air that forms can be vented to the atmosphere (to avoid excess pressure in the device). Further­more, the vent plugs allow air intake to pre­vent a vacuum from forming in the device.
Î Locate the vent plug on the opposite side
to the workplace of operating personnel.
Î On mounting valve accessories, make
sure that they can be operated from the workplace of the operating personnel.
Note
The workplace of operating personnel is the location from which the valve, actuator, and any mounted valve accessories can be ac­cessed to operate them.

Note
Greater deformation forces are required for new diaphragms (in comparison to already installed diaphragms). We recommend shaping the new diaphragms beforehand us­ing conventional hex screws:
− Tighten the conventional hex screws as de- scribed in step 28.
− Replace the conventional hex screws with the existing hex screws (34).
− Tighten the hex screws (34) as described in step 28.
29. For version with Type3724 Positioner: initialize the positioner (uEB8395).
7.3 Checking the concentricity
of the plug to the plug stem
2. Check the concentricity of the plug to the plug stem. Observe the values listed in Table6 and Table7.
3. If the concentricity deviates, use a suit­able tool (e.g. plastic hammer) and hit the plug until concentricity is achieved.
Tip
Instead of aligning the plug, the assembly (consisting of plug stem, diaphragm, and plug) can be ordered from SAMSON.

Note
Contact SAMSON's After‑sales Service department for malfunctions not listed in the table.

8.2 Emergency action

Putting the valve back into operation after a malfunction
Upon supply air or control signal failure, the valve moves to its fail-safe position (see sec­tion3.1).
Î Slowly open the shut-off valves. Allow
the process medium to slowly ow into the valve.
The plant operator is responsible for emer­gency action to be taken in the plant.
In the event of a valve malfunction:
1. Close the shut-off valves upstream and downstream of the control valve to stop the process medium from owing through the valve.
2. Check the valve for damage. If neces­sary, contact SAMSON's After-sales Ser­vice department.

sembly
!
DANGER
Risk of bursting in pressure equipment. Control valves and pipelines are pressure equipment. Improper opening can lead to valve components bursting.
− Before starting any work on the control valve, depressurize all plant sections con­cerned as well as the valve.
− Drain the process medium from all the plant sections concerned as well as the valve.
− Wear personal protective equipment.
!
WARNING
Risk of personal injury due to residual pro­cess medium in the valve. While working on the valve, residual process medium can escape and, depending on its properties, may lead to personal injury, e.g. (chemical) burns. Wear protective clothing, safety gloves, and eyewear.
!
WARNING
Risk of burn injuries due to hot or cold com­ponents and pipeline. Valve components and the pipeline may be­come very hot or cold. Risk of burn injuries.
− Allow components and pipelines to cool down or heat up.
− Wear protective clothing and safety gloves.
!
NOTICE
Diaphragm damage through the use of an incompressible medium. Closing the valve when the shut‑off valves upstream and downstream of the valve are closed may lead to the diaphragm rupturing in plants with liquid media owing through them. Only close the valve after opening the shut‑ off valves upstream and downstream of the control valve.

9.1 Decommissioning

To decommission the control valve for service and repair work or disassembly, proceed as follows:
1. Close the shut-off valves upstream and downstream of the control valve to stop the process medium from owing through the valve.
2. Completely drain the pipelines and valve.
3. Disconnect and lock the pneumatic air supply to depressurize the actuator.
4. If necessary, allow the pipeline and valve components to cool down or heat up.
9.2 Removing the valve from
the pipeline
1. Put the control valve out of operation (see section9.1).
2. Cut the pipeline in front of the weld seam.
46 EB 8048-2/-3 EN
3. Remove the valve from the pipeline (see section4.2).
9.3 Removing the actuator
from the valve
See associated actuator documentation.

9.4 Disposal

Î Observe local, national, and internation-
al refuse regulations.
