1 General
This chapter contains basic instructions for using the valve and explanations of illustra-
tion conventions. It also contains information about the design and structure.
The term valve in these Operating Instructions refers to GEA ECOVENT® Valve Type N_/
ECO.
1.1 Information about the document
1.1.1 Purpose and structure of the document
The objective of these Operating Instructions is to provide information on how to oper-
ate the valve. To achieve this, it is divided into several chapters which are oriented on
the various life phases of the valve. Compliance with the instructions will enhance the
valve's longevity and reliability, and reduce the likelihood of harm to individuals or dam-
age to property. The Operating Instructions also acts as the basis for creating operating
instructions.

2 Safety
This chapter describes the minimum requirements for the intended use of the valve. It
forms the basis for safe operation of the valve.
2.1 Intended use
The valve is used for opening and closing pipeline sections.
Proper use of the valve also includes compliance with these Operating Instructions.
The medium should preferably ow in the opening direction of the valve disk to avoid
pipe hammers when the valve is opened or closed.
In a closed pipe system, hydraulic pressure build-up may occur when the valve switches
and result in seal damage.
INFO The manufacturer will not accept any liability for damage resulting from
any use of the valve which is not in accordance with the designated use of
the valve. The risk is borne solely by the operating company.
2.1.1 Requirements for the operation
The prerequisite for the reliable and safe operation of the valve is proper transportation
and storage as well as professional installation and assembly. Operating the unit within
the limits of its designated use also involves adhering to the operating, maintenance
and servicing instructions.
2.1.2 Pressure equipment directive
The valve is a piece of pressure equipment (without safety function) in the sense of the
pressure equipment directive 2014/68/EU: Classied according to Annex II in category
1.
According to the scope of directive 2014/34/EC, article 1, paragraph 2, f), the excep-
tion of the directive applies, due to conformity with the Machinery Directive
2006/42/EC.
The nominal diameters smaller than DN 25 are subject to article 4, paragraph 3 of the
Pressure Equipment Directive which species sound engineering practice.
Nominal diameters ≥ IPS 4“; DN 125 valid for the uid group II.
In the event of any deviations, GEA Tuchenhagen GmbH will supply a special Declara-
tion of Conformity.
2.1.3 ATEX directive
In areas with an explosive atmosphere, only valves suitable for use in such areas may be
used.
Refer to and observe the additional instruction manual “ATEX version valves”. For de-
tails regarding the marking of valves for potentially hazardous areas also refer to the
additional instruction manual “ATEX version valves”.
If these valves are used in areas with a potentially explosive atmosphere, it is mandatory
to comply with directive 2014/34/EC with respect to all ignition hazards.
2.1 Intended use - 13 / 106

2.1.4 Improper operating conditions
The operational reliability of the valve cannot be ensured under improper operating
conditions. Therefore avoid improper operating conditions.
Operating the valve is not permitted if
●Persons or objects are in the danger zone.
●Safety devices are not working or were removed.
●Malfunctions have been detected on the valve.
●Damage has been detected on the valve.
●Maintenance intervals have been exceeded.
2.2 Modication
Subsequent alterations of the valve are not permitted. Otherwise you will have to un-
dergo a new conformity process in accordance with the EC Machinery Directive on your
own.
In general, only genuine spare parts supplied by GEA Tuchenhagen GmbH should be
tted. This ensures the reliable and economical operation of the valve.
2.3 Structure of warning notices
Warning notices warn of hazards which can occur when certain actions are carried out.
The warning notices described below are used in this document. The extent of hazards
is classied in risk levels and can be recognised by the respective signal words.
2.3.1 Preceding warning notices
Preceding warning notices are used when there is a hazard during a sequence of ac-
tions. Warning notices are colour-highlighted and supplemented by a pictogram in the
event of possible personal injury.
Figure 2-1 - Structure of a preceding warning notice
2.3.2 Integrated warning notices
Integrated warning notices are used when there is a hazard involved in a single action
step.
Figure 2-2 - Structure of an integrated warning notice
2.3.3 Signal words
IMPORTANT
The signal word IMPORTANT indicates a hazard that could result in property damage if
not avoided.
14 / 106 - 2.2 Modication
0000000576 - 001 - EN-GB

CAUTION
The signal word CAUTION indicates a hazard with a low risk level which could result in
light to medium injuries if not avoided.
WARNING
The signal word WARNING indicates a hazard with a medium risk level which could re-
sult in death or severe injury if not avoided.
DANGER
The signal word DANGER indicates a hazard with a high risk level which will result in
death or serious injury if not avoided.

●In the event of malfunctions, shut down the valve (disconnect from the power and
air supply) and secure it against being used.
●Before starting any maintenance, servicing or repair work, disconnect the valve from
the power supply and secure it against inadvertently being switched back on again.
●Only allow a qualied electrician to carry out any work on the electrical power sup-
ply.
●Check the electrical equipment of the valve at regular intervals. Immediately remedy
loose connections and molten cables.
●If work on live parts cannot be avoided, call in a second person, who can operate
the main switch in case of an emergency.
2.6 Personal protective equipment - 17 / 106

●Never reach into the lantern (9) or the valve housing (391) when the valve is switch-
ing. Fingers can be crushed or cut off.
●On a spring-closing valve there is danger of injury when the clamp connection (43) is
opened, as the released spring pretension will suddenly lift the actuator. Therefore,
release the spring tension before detaching the clamp connection (43) by supplying
the actuator (A) with compressed air.
●The housing sockets (391) have very sharp edges. When transporting and installing
the valve be sure to wear suitable protective gloves.
●On versions with proximity switch holder do not put your ngers in the slots (C).
Dangerous situations can be avoided by safety-conscious and proactive behaviour of
the personnel and by wearing personal protective equipment.
Danger Cause Measure
Danger to life Inadvertent switch-on of the valve Effectively disconnect all components,
effectively prevent switch-on.
Electric power Observe the following safety rules:
1.Isolate from the power supply.
2.Take appropriate measures to pre-
vent switch on.
3.Test absence of voltage.
4.Earthing and short-circuiting.
5.Cover or safeguard any adjacent
live parts.
Spring tension in the actuator Danger to life caused by the pressur-
ised spring in the actuator. Do not
open the actuator, rather return it to
GEA Tuchenhagen for proper disposal.
Risk of injury Danger presented by moving or sharp-
edged parts
The operator must exercise caution
and prudence.
For all work:
●Wear suitable work clothing.
●Never operate the machine if the
cover panels are not correctly t-
ted.
●Never open the cover panels dur-
ing the operation.
●Never reach into openings.
As a precautionary measure, wear per-
sonal protective equipment in the vi-
cinity of the valve:
●Protective gloves
●Safety shoes
Environmental dam-
age
Operating materials with properties
which are harmful to the environment
For all work:
●Collect lubricants in suitable col-
lecting vessels.
●Dispose of lubricants in accord-
ance with the pertinent regula-
tions.
