March 2023 edition
Subject to technical changes
Safety instructions and safety measures
− A actuator unit that is subsequently installed on the valve is
adapted to the valve and is correctly adjusted in the end po-
sitions, and in particular in the closed position of the valve.
− The pipe system and control system are properly installed
and regularly checked. The wall thickness of the valve body is
measured such that an additional load of the usual magni-
tude is taken into account for a pipe system installed properly
in this way.
− The valve is connected properly to these systems.
− The customary fl ow rates in continuous operation are not ex-
ceeded in this pipe system.
− PFEIFFER is contacted in the case of abnormal operating con-
ditions, such as vibrations, hydraulic shock, cavitation and
also small amounts of solid matter in the medium, especially
abrasive matter.
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 fa-
miliar with the applicable regulations concerning occupational
safety and accident prevention and observe them.
Applicable standards and directives
− The valves ful fi l the requirements of the European Pressure
Equipment Directive 2014/68/EU and the European Ma-
chinery Directive 2006/42/EC.
In the case of valves provided with a CE marking, the Decla-
ration of Conformity provides information about the conform-
ity assessment procedure that was used.
The corresponding declarations of conformity are available
in the Annex of this EB, see chapter “14 Certi
fi cates“.
− According to an ignition hazard assessment according to
DIN EN ISO 80079-36, PFEIFFER valves do not have any
own potential ignition sources and therefore are not subject
to Directive 2014/34/EU.
CE marking based on this standard is not permitted. The in-
clusion of valves in the equipotential bonding of a plant ap-
plies independently of the directive for all metal parts in po-
tentially explosive areas.
Valves with plastic lining (PFA, PTFE) through which chargea-
ble media
fl ows during operation, must be provided with an
electrostatically dissipative plastic lining whose surface resist-
ance does not exceed a value of 1 G
Ω (10
9
Ω ) in accord-
ance with DIN EN ISO 80079-36.
1.1 Notes regarding possible severe
personnel injury
Hazards and ineffectiveness of the warranty!
In the case of non-compliance with the following hazard and
warning information, hazards may arise and the warranty pro-
vided by PFEIFFER may become invalid.
Ö
Observe the following hazards and warning information.
Ö
Contact PFEIFFER in the case of questions:
Hazards and damage due to unsuitable valves!
Valves whose permissible pressure/temperature range (=”rat-
ing”) is not suf
fi cient for the operating conditions can pose a
danger to the user and cause damage to the pipe system.
Ö
Only operate valves whose permissible pressure/temperature
range (=”rating”) are suf
fi cient for the operating conditions,
see the data sheet

TB 01a)
Risk of bursting of the pressure equipment!
Valves and pipes are pressure equipment. Improper opening can
cause the bursting of valve components.
Ö
Observe the maximum permissible pressure the valve and
plant.
Ö
Before working on the valve, depressurise the concerned
plant parts and the valve.
Ö
Before removing the valve from the pipe, completely release
the pressure in the pipe so that the medium does not escape
uncontrolled from the line.
Ö
Empty the medium from the concerned plant parts and valve.
(Wear protective equipment).
1.2 Notes regarding possible personnel injury
Hazards due to incorrect valve use!
The incorrect use of the valve can represent a hazard for the user
and cause damage to the pipe system that are then no longer the
responsibility of PFEIFFER.
Ö
The lining selected for the parts of the valve that come into
contact with the media must be suitable for the utilised me-
dia, pressures and temperatures.
Danger of burning due to hot or cold components and pipes!
Depending on the utilised medium, valve components and pipes
can become very hot or very cold and cause burns upon contact.
Ö
Valves must be protected against contact in the case of oper-
ating temperatures >+50°C or <-20°C together with the pipe
connections.
