Safety instructions and safety measures
− The start-up and shut-down processes are a part of the
operating process and as such, are not a part of these
installation and operating instructions. SAMSON LEUSCH
cannot make a statement about these processes, as the
operational details (e.g. differential pressures and
temperatures) differ individually and are only known to the
operator.
Obligation of operating personnel to exercise diligence
Operating personnel must be familiar with this installation and
operating manual and the applicable documents and comply
with the indicated hazard information, warning information and
other information. Furthermore, operating personnel must be
familiar with the applicable regulations concerning occupational
safety and accident prevention and observe them.
Applicable standards and directives
The valve fulfi ls the requirements of the following European
Directives:
− 2014/68/EU Pressure Equipment Directive
− 2006/42/EC Machinery Directive
− 2014/35/EU Low Voltage Directive
− 2014/30/EC Electromagnetic Compatibility
− 2014/34/EU Equipment and protective systems intended for
use in potentially explosive atmospheres
In the case of valves provided with a CE marking, the Declaration
of Conformity provides information about the conformity
assessment procedure that was used, see Chapter 14.
Non-electrical valves do not have their own potential ignition
sources pursuant to the ignition hazard assessment in compliance
with EN ISO 80079-36, even in the case of seldom occurring
operational failures, and therefore are not subject to Directive
2014/34/EU.
Ö For the connection to the equipotential bonding system,
observe Paragraph 6.4 of EN60079-14, VDE0165-1.
− NACE
As regards the use or application of materials according to
NACE MR0175 / ISO15156 as well as NACE MR0103
(materials in an environment containing H2S) the designation
of the standard in the material or test certifi cates does not
indicate suitability for use of the butterfl y valve.
This depends additionally on the operating and
environmental parameters, to which generally only the plant
operator has access. Therefore the suitability for use of such
butterfl y valves must always be checked by the plant
manufacturer/operator.
− SIL
The suitability for use of butterfl y valves in (SIL) protective
circuits must be documented in separate agreements.
The below requirements are described in standards (e.g.
VDI2180, EN61508, EN61511) and in the applicable
SAMSON Group Manual (Functional safety for control
valves, rotary plug valves, ball valves and control butterfl y
valves; WA236).
− Oxygen
Butterfl y valve types LTR43-9.2, LTR43-9.4 and LTR43-9.9
are suitable for use in applications in which the oxygen
content of the operating media is greater than or equal to
35% (Vol.). All parts coming into contact with the medium are
cleaned oil and grease free and the butterfl y valve is
protected by means of a specifi c protective packaging
against dirt and environmental infl uences.
All maintenance and repair work must be carried out in an
oil and grease-free environment (clean room).
The utilised tools as well as personal equipment must comply
with the cleanliness requirements.
The required cleanliness of the butterfl y valve must be
ensured through suitable measures prior to reinstallation.
For butterfl y valves to be used in oxygen applications, when
ordering spare parts, it must be specifi cally indicated that
they are for “OXYGEN USE” and the corresponding
measures must be observed.

1.1 Notes regarding possible severe
personnel injury
The following list indicates only generally-applicable information.
The respective chapters can contain hazard information that, due
to context, is provided in addition or is formulated slightly
differently.
Danger due to falling of suspended loads!
Ö Do not stand under suspended loads.
Ö Secure the transport paths.
