Safety instructions and measures

1 Safety instructions and measures

Intended use

The SAMSON Type3321CT Globe Valve in combination with an actuator (e.g. Type3379

Pneumatic Actuator) is designed to regulate the ow rate, pressure or temperature of liquids,

gases or vapors.

The valve with its actuator is designed to operate under exactly dened conditions (e.g. oper-

ating pressure, process medium, temperature). Therefore, operators must ensure that the con-

trol valve is only used in operating conditions 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 applica-

tions or conditions than specied, 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 control valve is not suitable for the following applications:

−Use outside the limits dened during sizing and by 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. 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.

6 EB 8115 EN

Safety instructions and measures

Personal protective equipment

We recommend checking the hazards posed by the process medium being used (e.g.

uGESTIS (CLP) hazardous substance database).

ÎProvide protective equipment (e.g. safety gloves, eye protection) appropriate for the pro-

cess medium used.

ÎWear hearing protection when working near the valve.

ÎCheck with the plant operator for details on further protective equipment.

Revisions and other modications

Revisions, conversions or other modications of 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

Upon supply air or control signal failure, the valve moves to its fail-safe position (see sec-

tion3.1). The fail-safe action of the actuator is the same as its direction of action and is spec-

i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 operat-

ing 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 oper-

ating instructions, especially for installation, start-up and service work.

We also recommend checking the hazards posed by the process medium being used (e.g.

uGESTIS (CLP) hazardous substance database).

ÎObserve safety measures for handling the device.

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 8115 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 specied hazard statements, warnings

and caution notes. Furthermore, the operating personnel must be familiar with the applicable

health, safety and accident prevention regulations and comply with them.

Referenced standards and regulations

The control valves comply with the requirements of the European Pressure Equipment Direc-

tive 2014/68/EU. Valves with a CE marking have an EU declaration of conformity, which

includes information about the applied conformity assessment procedure. This EU 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.

ÎFor 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

1.1 Notes on possible severe personal injury

DANGER

Risk of bursting in pressure equipment.

Valves and pipelines are pressure equipment. Improper opening can lead to valve

components bursting.

ÎBefore starting any work on the valve, depressurize all plant sections concerned as

well as the valve.

ÎDrain the process medium from all the plant sections concerned as well as the

valve.

ÎWear personal protective equipment.

1.2 Notes on possible personal injury

WARNING

Crush hazard arising from moving parts.

The control valve contains moving parts (actuator and plug stems), which can injure

hands or ngers if inserted into the valve.

ÎDo not insert hands or ngers into the yoke while the valve is in operation.

ÎWhile working on the control valve, disconnect and lock the pneumatic air supply.

Risk of personal injury when the pneumatic actuator vents.

While the valve is operating, the actuator may vent during closed-loop control or when

the valve opens or closes.

ÎInstall the control valve in such a way that the actuator does not vent at eye level.

ÎUse suitable silencers and vent plugs.

ÎWear eye protection when working in close proximity to the control valve.

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.

ÎIf possible, drain the process medium from all the plant sections concerned and the

valve.

ÎWear protective clothing, safety gloves, and eyewear.

EB 8115 EN 9

Safety instructions and measures

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.

ÎAllow components and pipelines to cool down or heat up.

ÎWear protective clothing and safety gloves.

1.3 Notes on possible property damage

NOTICE

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.

ÎFlush the pipelines before start-up.

ÎObserve 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.

ÎOnly use the process medium specied for sizing.

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 tight-

ened torques lead to parts wearing out quicker. Parts that are too loose may cause leak-

age.

ÎObserve 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.

ÎOnly use tools approved by SAMSON (uAB0100).

Risk of valve damage due to the use of unsuitable lubricants.

The lubricants to be used depend on the valve material. Unsuitable lubricants may cor-

rode and damage the valve surface.

ÎOnly use lubricants approved by SAMSON (uAB0100).

10 EB 8115 EN

Design and principle of operation

3 Design and principle of oper-

ation

The single-seated Type3321CT Globe Valve

is preferably combined with a SAMSON

Type3379 Pneumatic Actuator.

The seat (2) and plug with plug stem (3) are

installed in the body (1). The plug stem has a

thread to screw it onto the actuator stem and

is sealed by the spring-loaded packing (8).

The process medium ows through the valve

in the direction indicated by the arrow in the

ow-to-open direction. The plug position de-

termines the cross-sectional area between

the seat and plug.

The position of the plug is changed by the

control signal acting on the actuator.

3.1 Fail-safe positions

Depending on how the compression springs

are arranged in the pneumatic actuator, the

valve has two fail-safe positions that become

effective when the supply air fails:

−Fail-close: the valve is closed upon air

supply failure.

−Fail-open: the valve is opened upon air

supply failure.
