1.0 General information on operating instructions
These operating instructions provide information on mounting and maintaining the fittings.
Please contact the supplier or the manufacturer in case of problems which cannot be
solved by reference to the operating instructions.
They are binding on the transport, storage, installation, start-up, operation, maintenance
and repair.
The notes and warnings must be observed and adhered to.
- Handling and all work must be carried out by expert personnel or all activities must be
supervised and checked.
It is the owner’s responsibility to define areas of responsibility and competence and to
monitor the personnel.
- In addition, current regional safety requirements must be applied and observed when
taking the fittings out of service as well as when maintaining and repairing them.
The manufacturer reserves the right to introduce technical modifications at any time.
These Operating Instructions comply with the requirements of EU Directives.
2.0 Notes on possible dangers
2.1 Significance of symbols
2.2 Explanatory notes on safety information
In these Operating and Installation Instructions dangers, risks and items of safety
information are highlighted to attract special attention.
Information marked with the above symbol and “ATTENTION!” describe practices, a failure
to comply with which can result in serious injury or danger of death for users or third parties
or in material damage to the system or the environment. It is vital to comply with these
practices and to monitor compliance.
All other information not specifically emphasised such as transport, installation, operating
and maintenance instructions as well as technical data (in the operating instructions,
product documentation and on the device itself) must also be complied with to the fullest
extent in order to avoid faults which in turn can cause serious injury to persons or damage
to property.
3.0 Storage and transport
- At -20°C to +65°C.
- The paint is a base coat to protect against corrosion during transportation and storage. Do
not damage paint protection.
ATTENTION !
. . . Warning of general danger.
ATTENTION !
- Protect against external force (like impact, vibration, etc.).
- Valve mountings such as actuators, handwheels, hoods must not be used to
take external forces, e.g. they are not designed for use as climbing aids, or as
connecting points for lifting gear.
- Suitable materials handling and lifting equipment should be used.
See catalog sheet for weights.

4.0 Description
4.1 Scope of applications
Butterfly valves are used for “interruption or restriction of the flow of liquids and gases”.
The information complies to the Pressure Equipment Directive 2014/68/EU.
It is the responsibility of the machine planner to ensure compliance.
The special markings on the valve must be taken into account.
Refer to the catalogue sheet to see which materials are used in standard versions.
Please contact the supplier or the manufacturer if you have any questions.
4.2 Operating principles
The valve is closed by turning the disc shaft clockwise.
The shaft moves through 90°.
ATTENTION !
- Refer to the data sheet for applications, limits on use and possibilities.
- Certain media require or preclude the use of special materials.
- The valves are designed for standard operating conditions. If conditions exceed
these requirements, e.g. aggressive or abrasive media, the operator should
state the higher requirements when ordering.
- Valves made from grey cast iron are not authorised for use in systems subject
to TRD 110.

5.0 Installation
5.1 General remarks on installation
The following points should be taken into account besides the general principles governing
installation work:
- Planners / construction companies or operators are responsible for positioning and
installing products.
- The valves are designed for application, not influenced from weather.
- For application outside or in adverse environments like corrosion-promoting conditions
(sea water, chemical vapours, etc.), special constructions or protective measures are
recommended.
- The valves are not permitted for subsurface installation.
5.2 Installation of accessories
Optional accessories (e.g. limit switches) supplies with valves must be fitted as required for
their functions as shown in the plants of the plant.
ATTENTION !
- Remove flange covers if present.
- The interior of valve and pipeline must be free from foreign particles.
- The direction of flow need not be taken into account.
- Steam line systems should be designed to prevent water accumulation.
- Lay pipelines so that damaging transverse, bending and torsional forces are
avoided.
- Protect valves from dirt during construction work.
- Connection flanges must mate exactly.
- Valve mountings such as actuators, handwheels, hoods must not be used to
take external forces, e.g. they are not designed for use as climbing aids, or as
connecting points for lifting gear.
- Flooding of the butterfly valve is not permissible.
- Suitable materials handling and lifting equipment should be used.
See data sheet for weights.
- The shaft can be in any position except for DN350 up to DN600 (preferably
horizontal shaft).
- No gaskets required between flanges, flexible gaskets are not allowed.
- The butterfly valve must be installed in open position if possible, but the disc
should not protrude beyond the housing.
- Large actuators with horizontal application must be supported.
- Avoid damage to the rubber sheathing during handling, storage and installation.
- Do not heat the valve (e.g. by welding, grinding, etc.) above its service
temperature (refer to data sheets).
- Protect actuators from excessive ambient temperatures
(refer to operating instructions for actuator).
- If the butterfly valve is in operation as a pipeend valve, regard DIN EN 294
point 5.

6.0 Putting the valve into operation
7.0 Care and maintenance
Maintanance and maintenance-intervals have to be defined by the operator according to
the requirements.
ATTENTION !
- Before putting the valve into operation, check material, pressure, temperature
and direction of flow.
- Regional safety instructions must be adhered to.
- Residues in piping and valves (dirt, weld beads, etc.) inevitably lead to leakage.
- Touching the valve when it is operating at high (> 50°C) or low (< 0°C) media
temperatures can cause injury.
Affix warning notice or protective insulation as appropriate!
Before putting a new plant into operation or restarting a plant after repairs or
modification, always make sure that:
- All works has been completed!
- The valve is in the correct position for its function.
- Safety devices have been attached.
ATTENTION !
- It is advisable to actuate the valve at least once a month.
- When used as an end-blockage, a safety precaution (e.g. plug-in disc, blind
flange etc.) is demanded by maintenance works.

7.1 Changing seat and O-ring seal
(ZIVA®-Z / ZIVA®-G)
fig. 10
- Observe safety instructions
- Grease seat (pos. 2) when changing
Lubricant: e.g. Berusoft 30 valve grease
obtainable from: Carl Bechem GmbH, Weststrasse 120, D-58089 Hagen
or a lubricant suitable for this application.
ATTENTION!
- Always ensure that the lubricant is compatible with the medium.
- It is not safe to replace the O-ring seal (pos. 11) until the system has cooled
down and the plant is pressureless.
- For safety reasons we recommend that the O-ring seal (pos. 11) only be
changed when disassembled.
- Prior to disassembling the butterfly valve note points 10.0 and 11.0.
- When the butterfly valve is activated there is a crushing hazard between valve
disc and body.
- Maintenance work inside the pipeline (large nominal diameters) should only be
carried out when the butterfly valve is safely deactivated (disconnect actuator
from power supply).
