Intended use
The SAMSON LEUSCH control and shut-off butterfl y valve type
LTR 43 is designed for use in combination with an actuator for
the regulation of the volume fl ow, pressure and temperature of
fl uid, gaseous or vaporous media.
− The butterfl y valve and its drive are designed for precisely
defi ned conditions (e.g. operating pressure, utilised medium,
temperature).
Therefore the operator must make sure that the butterfl y valve
is only used when the conditions of use comply with the de-
sign criteria defi ned in the order.
If the operator would like to use the butterfl y valve in other
applications or environments, they must contact SAMSON
LEUSCH.
− SAMSON LEUSCH shall not be held liable for damage that
result from non-compliance with the intended use, as well as
for damage that results from external forces or external infl u-
ences.
− Limits of use, areas of use and possible uses can be found in
the technical data and on the type plate.
Reasonably foreseeable misuse
The butterfl y valve is not suited for the following areas of use:
− Use outside of the technical data and the limits defi ned by the
design.
− Use outside of the limited defi ned by the attachments installed
on the butterfl y valve.
Furthermore, the following activities are considered unintended
use:
− Use of third-party spare parts
− Performance of maintenance and repair work that is not de-
scribed
Qualifi cation of operating personnel
The butterfl y valve may only be installed in observance of the
recognised rules of technology, commissioned, serviced and re-
paired by specialist personnel.
− Specialist personnel in terms of this installation and operating
manual are persons who, on the basis of their vocational ed-
ucation, knowledge and experience and knowledge of the
relevant standards, are capable of evaluating the assigned
tasks and identifying possible hazards.
− In the case of valves with an explosion-protection version,
personnel must have been trained or instructed or be author-
ised to work on explosion-protected devices in plants at risk
of explosion.
Personal protective equipment
SAMSON LEUSCH recommends obtaining information regarding
the hazards resulting from the medium in use, for example using
the GESTIS substance database.
Depending on the medium that is used and/or the respective ac-
tivity, the following protective equipment, among others, may be
necessary:
− Protective garments, protective gloves and eye protection
when using hot, cold, aggressive and/or corrosive media
− Hearing protection when working in the vicinity of the butter-
fl y valve
− Industrial safety helmet
− Safety harness, if there is a danger of falling (e.g. if working
unsecured at a height)
− Safety shoes, e.g. with protection against static discharge
− Request additional protective equipment from the plant oper-
ator.
Changes and other modifi cations
Changes, conversions and other modifi cations to the valve are
not authorised by SAMSON LEUSCH. They are made at your
own risk and can lead to safety risks, for example, that cause the
valve to no longer fulfi l the prerequisites required for its use.
Protective devices
If the butterfl y valve switches to a defi ned fail-safe position when
the pneumatic energy fails, it depends on the utilised butterfl y
valve, see the corresponding actuator documentation. In the case
of combinations of a butterfl y valve with single-acting actuators,
the butterfl y valve automatically switches to a certain fail-safe po-
sition in case of a pneumatic energy failure, see Chapter 3. The
fail-safe position corresponds to the effective direction and is in-
dicated on the type plate.
Warning of residual risks
To prevent personal injury or property damage, the operator and
operating personnel must use suitable measures to prevent the
hazards that can result from the fl ow medium and operating
pressure as well as the signal pressure and moving parts.
− Therefore, the operator and operating personnel must ob-
serve all the hazard information, warning information and
information in this installation and operating manual.
− Hazards that result from the specifi c work conditions at the
area of butterfl y valve use must be determined in an individu-
al risk assessment and made avoidable by corresponding in-
structions from the operator.
Obligation of the operator to exercise diligence
The operator is responsible for proper operation as well as com-
pliance with the safety regulations.
− The operator is responsible for providing operating personnel
with this installation and operating manual as well as the ap-
plicable documents and to provide instructions on proper op-
eration.
− Furthermore, the operator must ensure that operating person-
nel and third parties are not endangered.
− The operator is responsible that the limit values for the valve
defi ned in the technical data are not undershot or exceeded.
