Safety instructions and measures

1 Safety instructions and measures
Intended use
The Type 3595 Globe or Angle Valve in combination with an actuator (e.g. Pneumatic Actuator 3276 or SAMSON Type 3271 Pneumatic Actuator) is designed to regulate the flow rate,pressure or temperature of liquids, gases or vapors. The valve is suitable for throttling andon/off service in the oil and gas industry as well as for high-temperature applications in
power plants.
The valve with its actuator is designed to operate under exactly defined conditions (e.g. operating pressure, process medium, temperature). Therefore, operators must ensure that the control valve is only used in operating conditions that meet the specifications used for sizing thevalve at the ordering stage. In case operators intend to use the control valve in applications
or conditions other than those specified, contact RINGO.
RINGO 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 control valve is not suitable for the following applications:− Use outside the limits defined during sizing and by the technical data
− Use outside the limits defined by the valve accessories connected to the 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
Qualifications of operating personnel
The control valve must be mounted, started up, serviced and repaired by fully trained andqualified personnel only; the accepted industry codes and practices must 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 totheir specialized training, their knowledge and experience as well as their knowledge of theapplicable standards.
Welding operations are to be performed only by personnel who has the necessary qualification to perform the applied welding procedure and handle the materials used.

EB 8079 EN

1-1

Safety instructions and measures

Explosion-protected versions of this device must be operated only by personnel who has undergone special training or instructions or who is authorized to work on explosion-protected
devices in hazardous areas.
Personal protective equipment
RINGO recommends checking the hazards posed by the process medium being used (e.g.
u GESTIS (CLP) hazardous substances database). Depending on the process medium and/or the activity, the protective equipment required includes:− Protective clothing, gloves, eye protection and respiratory protection in applications withhot, cold and/or corrosive media− Wear hearing protection when working near the valve− Hard hat− Safety harness, e.g. when working at height− Safety footwear, if applicable ESD (electrostatic discharge) footwear
Î Check with the plant operator for details on further protective equipment.
Revisions and other modifications
Revisions, conversions or other modifications of the product are not authorized by RINGO.
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
The fail-safe position of the control valve upon air supply or control signal failure depends on
the actuator used (see associated actuator documentation). For example, when the valve is
combined with a SAMSON Type 3271 Pneumatic Actuator, the valve moves to a certain failsafe position (see the 'Design and principle of operation' chapter) upon supply air or control
signal failure. The fail-safe action of the actuator is the same as its direction of action and isspecified on the nameplate of SAMSON actuators.
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. Plant
operators and operating personnel must observe all hazard statements, warnings and caution notes in these mounting and operating instructions.

1-2

EB 8079 EN

Safety instructions and measures

Furthermore, the intended purpose may involve the use of the device in hazardous areas. In
this case, all work on the control valve must only be performed when no potentially explosive
atmosphere is present.
Hazards resulting from the special working conditions at the installation site of the valve mustbe identified in a risk assessment and prevented through the corresponding safety instructions drawn up by the operator.
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.
Operators are additionally responsible for ensuring that the limits for the product defined in
the technical data are observed. This also applies to the start-up and shutdown procedures.
Start-up and shutdown procedures fall within the scope of the operator's duties and, as such,are not part of these mounting and operating instructions. RINGO is unable to make any
statements about these procedures since the operative details (e.g. differential pressures andtemperatures) vary in each individual case and are only known to the operator.
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.
Referenced standards, directives and regulations
The control valves comply with the requirements of the European Pressure Equipment Directive 2014/68/EU. Valves with a CE marking have a declaration of conformity, which includes information about the applied conformity assessment procedure. The 'Certificates'
chapter contains this declaration of conformity.
Non-electric control valve versions whose bodies are not lined with an insulating material
coating do not have their own potential ignition source according to the hazard assessment
stipulated in Clause 5.2 of ISO 80079-36, even in the rare incident of an operating fault.
Therefore, such valve versions do not fall within the scope of Directive 2014/34/EU.
Î For connection to the equipotential bonding system, observe the requirements specified in
Clause 6.4 of EN 60079-14 (VDE 0165-1).

Safety instructions and measures! WARNING
Crush hazard arising from moving parts.
The control valve contains moving parts (actuator and plug stem), which can injure
hands or fingers if inserted into the valve.
Î Do not insert hands or finger into the yoke while the air supply is connected to theactuator.
Î Before working on the control valve, disconnect and lock the pneumatic air supply
as well as the control signal.
Î Do not impede the movement of the actuator and plug stem by inserting objects into
the yoke.
Î Before unblocking the actuator and plug stem after they have become blocked (e.g.
due to seizing up after remaining in the same position for a long time), release any
stored energy in the actuator (e.g. spring compression). See associated actuator
documentation.
Risk of personal injury due to residual process medium in the valve.
While working on the valve, residual medium can flow out of the valve and, depending
on its properties, cause personal injury, e.g. (chemical) burns.

Design and principle of operation

3 Design and principle of operation
See Fig. 3-1
Valve style and actuator
The Type 3595 Valve is a cage valve designed as globe or angle valve. The valve
can be combined with various electric, electrohydraulic and pneumatic actuators. This
documentation includes examples of the
combination with the Pneumatic Actuator
3276 or Type 3271 Pneumatic Actuator.
Cage valve
Different valve trims are used in theType 3595 Valve to meet application requirements. All valve trims have a plug
which is guided through a cage with very little clearance over the entire stroke. This cage
guide suppresses vibration of the closure
member, resulting in a better control performance at high energy forces created bychanges in pressure and flow rate. The plug
is available with or without pressure balancing.

The plug stem in the valve bonnet is sealedby either a PTFE or graphite packing, which
is either self adjusting or can be adjusted
manually.
The valve has a clamped-in seat. The seat isinserted into the seat bridge. The seat andcage are clamped into place by tightening
the body nuts.
Function
The medium flows through the valve as indicated by the arrow on the valve body. Achange in the pneumatic signal acting on theactuator changes the plug travel and how
far the valve is opened as a result. The plug
position and cage design determine the released cross-section and the resulting flowrate.

DesignThe plug is connected to the plug stem using
a form-fit connection. The plug stem is connected to the actuator stem by a stem connector which transfers the linear motion of
the actuator to the valve plug. The actuator isconnected using a special assembly, which
varies depending on the mounted actuator.
These assemblies are fitted with an externalanti-rotation fixture for the plug stem.

3.1 Fail-safe action
The fail-safe position of the control valve upon air supply or control signal failure depends on the actuator used (see associatedactuator documentation).
Depending on how the compression springs
are arranged in the SAMSON Type 3271
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 theactuator stem downward and close thevalve. The valve opens when the signal
pressure is increased enough to overcome the force exerted by the springs.

EB 8079 EN− Actuator stem retracts (FE)When the signal pressure is reduced or
the air supply fails, the springs move theactuator stem upwards and open thevalve. 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 SAMSONType 3271 Pneumatic Actuator can be reversed, if required. Refer to the mounting
and operating instructions of the pneumatic
actuator:u EB 8310-X for Type 3271

3-3

Design and principle of operation

3.2 Versions
Actuators
In these instructions, the preferable combination with a Pneumatic Actuator 3276 or aType 3271 Pneumatic Actuator is described.
The pneumatic actuator (with or without
handwheel) can be replaced by anotherpneumatic actuator in a different size, butwith the same travel.
Î Observe the maximum permissible actuator force.
Note
If the travel range of the actuator is larger
than the travel range of the valve, the springassembly in the actuator must be preloadedso that the travel ranges match. See associated actuator documentation.
The basic pneumatic actuator can be replaced by an actuator with additional handwheel, an electric actuator or an hydraulicpiston actuator.

Bypass and shut-off valves
RINGO recommends installing a shut-off
valve both upstream of the strainer anddownstream of the valve and installing a bypass line. The bypass ensures that the plantdoes not need to be shut down for service
and repair work on the valve.
Insulation
Control valves can be insulated to reduceheat energy transfer.
Refer to the instructions in the 'Installation'
chapter.
Safety guard
For operating conditions that require increased safety (e.g. in cases where the valve
is freely accessible to untrained staff), a safety guard must be installed to rule out a crush
hazard arising from moving parts (actuatorand plug stem). Plant operators are responsible for deciding whether a guard is to be
used. The decision is based on the risk posedby the plant and its operating conditions.

Bellows seal
The valve can be fitted with a bellows seal tomeet special requirements resulting from theprocess medium used.

3.3 Additional fittings
Strainer
RINGO recommends installing a strainer upstream of the valve. It prevents solid particles
in the process medium from damaging thevalve.

4 Shipment and on-site transport
The work described in this chapter is to be
performed only by personnel appropriately
qualified to carry out such tasks.

4.1 Accepting the delivered
goods
After receiving the shipment, proceed as follows:
1. Check the scope of delivery. Check thatthe specifications on the valve nameplatematch the specifications in the delivery
note. See the 'Markings on the device'chapter for nameplate details.
2. Check the shipment for transportation
damage. Report any damage to RINGO
and the forwarding agent (refer to delivery note).
3. Determine the weight and dimensions of
the units to be lifted and transported inorder to select the appropriate lifting
equipment and lifting accessories. Referto the transport documents and the 'Technical data' chapter.

4.2 Removing the packaging
from the valve

Î Leave the control valve in its transport
container or on the pallet to transport iton site.
Î Do not remove the protective caps fromthe inlet and outlet until immediately before installing the valve into the pipeline.
They prevent foreign particles from entering the valve.
Î Dispose and recycle the packaging in accordance with the local regulations.

4.3 Transporting and lifting thevalve! DANGER
Danger due to suspended loads falling.
Î Stay clear of suspended or moving
loads.
Î Close off and secure the transport paths.
! WARNING
Risk of lifting equipment tipping over andrisk of damage to lifting accessories due toexceeding the rated lifting capacity.
Î Only use approved lifting equipment andaccessories whose minimum lifting capacity is higher than the weight of thevalve (including actuator and packaging,
if applicable).

Observe the following sequence:Î Do not open or remove the packaging
until immediately before lifting to installthe valve into the pipeline.

EB 8079 EN

4-1

Shipment and on-site transport! WARNING
Risk of personal injury due to the control
valve tipping over.
Î Observe the valve's center of gravity.
Î Secure the valve against tipping over orturning.
! NOTICE
Risk of valve damage due to incorrectly attached slings.
Lifting eyelets/eyebolts on actuators are only
intended for mounting and removing the actuator as well as lifting the actuator without
valve. Do not use these lashing points to lift
the entire control valve assembly.
Î When lifting the control valve, make surethat the slings attached to the valve bodybear the entire load.
Î Do not attach load-bearing slings to theactuator, handwheel or any other parts.
Î Observe lifting instructions (see Chapter 4.3.2).

assembly. The sling only protects the control
valve from tilting while being lifted.
Tip
The valves in nominal sizes NPS 16(Class 300 to 900) and NPS 20 (Class 150

AppendixTools
In addition to the standard tool, special tools
are required to assemble and remove someparts. Use adjustable torque wrenches with astop signal or that indicate the torque being
applied to achieve the right tightening
torques. Valves in large nominal sizes often
require tightening torques that can only beachieved through additional torque multiplication by using a torque multiplier or hydraulic power tool.
The required special tools can be purchasedfrom RINGO. Contact our after-sales service.
