2.0 Danger Notices

2.1 Safety terms

The signal terms DANGER, CAUTION und NOTICE are used in this operating manual in case of
notices concerning special dangers, or for unusal information requiring a special marking.

DANGER! means that in case of non-observance there is danger to life and/or
considerable damage.

CAUTION! means that in case of non-observance there is danger of injury and/or
damage.

NOTICE! means that attention is drawn to technical correlations/connections.

Observance of other, not especially marked notices concerning transport, assembly, operation and
maintenance and other data (in the operating manual, product documentation and at the unit itself) is
also essential, in order to avoid disturbances that might affect direct or indirect damage to property or
injury to persons.

2.2 Safety notice
Non observance of safety instructions can lead to loss of any claim for damages.

Non observance can lead to the following mentioned dangers:

 Failure of important functions of the valve/plant
 Endangering of persons by electrical or mechanical influences.
 Protection against accidental contact for moving parts may not be removed as long as the

valve is in operation.

 Leakage of dangerous media (e.g. explosive, toxic, hot) must be removed in the way that

there is no danger for persons or environment. Laws and regulations must be observed.

2.3 Qualified staff

These are persons who are familiar with erection, assembly, starting, operation and maintenance of
the product and who have special qualifications acc. to their activities and functions, e.g.:

 Instruction and obligation to carry out and meet all regional and in-house orders and

requirements.

 Education or instruction according to the safety engineering standards in use and

maintenance of adequate safety and working protection equipment.

 Training in first aid.

2.4 Unauthorized modification and spare part production

Modification or changes of the valve are only allowed after agreement of the manufacturer. Original
drawings and accessories authorized by the manufacturer are for safety purposes. The use of other
parts or unauthorized constructive changes at the valve by third persons may cancel and abolish the
manufacturere’s liability for resulting consequences.

2.5 Unauthorized operation
Operational reliability of the delivered valve is only guaranteed in case of determined use in
accordance to paragraph 1 of the operating manual. The application limits mentioned on the type

sign may on no account be exceeded.

2.6 Safety information for the use in explosion-prone areas guideline 94/9/EC

 The temperature of the medium must not exceed the respective temperature class, and

respectively, the respective maximum permitted medium temperature as per operation
guideline.

 If the valve is heated (e.g. heating jacket), care must be taken, that the specified temperature

class is kept in the time.

 The valve must be connected to the ground.

In the case most simple this can be realized via pipe screws by means of tooth disc.
Otherwise the connection to the ground must be implemented by other measures e.g. cable
links.

 Control valves, electrical and electrical/mechanical drives as well as sensors must undergo a

separate conformity check as per ATEX. In doing so the respective safety and explosion
protection information in the operation instructions are to taken into special consideration.

 Any modifications whatsoever to the valve are not allowed. The ATEX approval is void with

immediate effect if the valve is modified without prior authorisation (even including painting).

 UNI-Geräte GmbH must be consulted before any modifications are made.

Furthermore we point out the guideline 95/C332/06(ATEX 118a), which include the minimum
regulations for the improvement of the health-related situation and the safety of the employees, who
might be jeopardized by an explosive atmosphere.

3.0 Handling

3.1 Transport

For any transport works, the generally recognised technical rules and standards as well as rules for
prevention of accidents must be observed.

In case of transport, storage and stopping, the flange protection caps must be mounted at both valve
flanges.

The goods to be transported must be carefully treated. During transport, the valve must be protected
against strokes, impacts or vibration. The coat of lacquer may not be damaged. Transport temperature
is –20°C up to + 60°C.

Never transport the valve at screwed cable glands, appliance plugs or add-on units. The valve
can be transported at ring nuts, flange borings or by means of a belt under the solenoid drive.

4.0 Product Description

The UNI-Geräte Electro – solenoid valve EVS is a directly controlled, currentless closed safety shut-off
valve acc. to DIN EN 13611, DIN 3394-1 and DIN EN 161 (DIN EN 264) with solenoid drive.

Sectional drawing 11.1 Fig. 1 - 4 shows the valve construction.

4.1 Function

By switching on the solenoid drive, the solenoid core (207) is drawn against the upper part (106). The
pressure spring (503) is pressed and the balance piston (220) releases the valve cross section. The
valve is open.
The valve closes by switching off, interruption or failure of power energy to solenoid drive. Due to
press of the pressure spring (503) the balance piston closes (220). The valve is closed at 15% of
nominal voltage.

10.0 Explanations on Codes and Directives

The Council of the European Community has passed common guidelines for the free exchange of
goods within the Community; these guidelines determines a minimum of requirements for safety and
protection of health. The type test confirms that products correspond to the EC guidelines, i.e. are in
conformity with the relevant, especially harmonized standards. The directives DIN EN 264 refer to oil
solenoid valve (mechanical part).
Notes concerning directives DIN EN 264:
The valves must be developed, manufactured and checked under observation of standard DIN EN

264. This is proven by the type test.
Notes concerning directives 2006/42/EG (machine directives):
The valves were developed, manufactured and checked under observation of directive 2006/42/EG.
Notes concerning directives 97/23/EG (directive for pressure appliances, DGRL):
It was confirmed that the manufacturer UNI-Geräte E. Mangelmann Elektrotechnische Fabrik GmbH
fulfils quality assurance with regard to design control, manufacturing and final inspection as per the
requirements of 98/23/EG annex III module H. The oil solenoid valves correspond to the basic
requirements of guidelines 97/23/EG. Valves with permitted operating pressures of ≤ 0,5bar and DN ≤
25 do not all under 97/23/EG. The marks as per 97/23/EG must only be implied in case of products,
which fall under DGRL and are in Kat I or higher. Fluid group 1 includes explosion-prone, inflammable
and poisonous matters. Die Fluid group 2 includes media, which are no included in fluid group 1.
Note concerning ex-guideline 94/9/EC (explosion guideline ATEX):
The product is not subject to guideline 94/9/EC, since due to the loads occurring during practical
operation, there is no effective source of ignition even in case of an error case to be assumed. This
also applies for spring-loaded components, in gas-filled rooms. In case of electric drives, sensors or
other electric components the application as per 94/9/EC is to be checked separately.

National Codes and Directives

For the use of safety shut-off devices in accordance with DIN EN 12952-8 or DIN EN 746, the
requirements of DIN EN 264 have to be satisfied. This is confirmed by a type test or by an acceptance
test certificate to EN 10204-3.2.
