3 Safety advice
Depending on the technical circumstances and the time under and at which the butterfly valves
are mounted, adjusted and commissioned, you must take into account particular safety aspects in
each case!
If, for example, a butterfly valve works a slide in an operational chemical plant, the potential
hazards of commissioning have another dimension from that when this is only being carried out for
test purposes an a „dry“ part of the plant in the assembly room!
Since we do not know the circumstances at the time of the mounting/adjustment/commissioning,
you may find advices on hazards in the following descriptions which are not relevant to you.
Please observe (only) the advices which applies to your situation!
3.1 Personal safety
3.1.1 Safety advices for mounting
We wish to point out expressly that the mounting, adjusting and at accessories the pneumatical
and eletrical installation of the butterfly valves must be carried out by trained specialist person-
nel having mechanical, pneumatical and electrical knowledge!
Secure that the machine / plant come up to the Machinery Directice after the mounting and instal-
ling of the butterfly valves.
Switch off all the devices / machines / plant affected by mounting or repair.
If appropriate, isolate the devices / machines / plant from the mains.
Check (for example in chemical plants) whether the switching off of devices / machines / plant
will cause potential danger.
If appropriate, in the event of a fault in the butterfly valve (in a plant which is in operation) inform
the shift forman / safety engineer or the works manager without delay about the fault, in order,
for example, to avoid an outflow / overflow of chemicals or the discharge of gases in good time
by means of suitable measures!
Before mounting or repairing, remove the pressure from pneumatic / hydraulic devices / machi-
nes / plant.
If necessary, set up warning signs in order to prevent the inadvertent starting up of the devices /
machines / plant.
Observe the respective relevant professional safety and accident prevention regulations when
carrying out the mounting / repair work.
Check the correct functioning of the safety equipment (for example the emergency push off but-
tons/ safety valves, etc)!

3.1.3 Safety advice for adjustment / starting
As a result of the starting (pneumactic, electric or by hand) of the butterfly valves the flow of
gases, steam, liquids, etc. may be enabled or interrupted! Satisfy yourself that, as a result of the
starting or the test adjustment no potential hazards will be produced for the personnel or the
environment!
If necessary, set up warning signs in order to prevent the inadvertent starting up or shutting down
of the device / machine / plant.!
By ending the adjustment check the correct function and should the occasion arise the position
of the butterfly valve.
Check the function of the limit switches (option)!
Check, whether the butterfly valve will be closed totally, if the control signals the appropriate
limit stop!
Through suitable measures, prevent links being trapped by moving actuating elements!
Check the right function of all safety devices (for example emergency push off buttons / safety
valves)!
Carry out the starting and the adjustments only in accordance with the instructions discribed in
this documentation!
Adjusting switchs on butterfly valves with options (e.g. actuators, solenoid valves, limit swit-
ches) there is the risk that live parts (230 V AC~) can be touched!
Therefore the adjustments must be carried out only by the electrican or a person having adequate
training, who is aware of the potential hazard!
Safety Advice

11/02 http://www.end.de 9
3.1.4 Safety advice for maintaining / repairing
Do not carry out any maintenances / repairs if the butterfly valve will be under pressure.
Before disassembling the butterfly valve some essential points should be clarified!
• Will the butterfly valve to be disassembled be replaced by another immediately?
• If appropriate, does the production process of the plant needed to be stopped?
• Is it necessary to inform specific personnel about the disassmbly?
If necessary, inform the shift foreman/ safety engineer or the manager about the maintenance
or repair without delay in order, for example, to avoid an outflow/ overflow of chemicals or a
discharge of gases in good time by means of suitable measures!
You have to relieve the pressure in the pipes in which the butterfly valve is mounted.
Switch off pilot pressure and the power supply and relieve the pressure in the pipes.
If necessary set up warning signs in order to prevent
• the inadvertent starting up of the devices/machines/plants in which the butterfl
valve is mounted
• the switching on of pilot medium supply, pilot power supply and/or the power supply
of actuators and accessories.
In case of defect in the butterfly vavle make contact to the supplier. The telephone number will be
found on the back cover of these mounting and installation manual.
If you ascertain a damage of the butterfly valve, isolate the device from the mains. Please observe
the safefy advices.
Do not mount, start or adjust the butterfly valve if itself, the pipes or a mounted actuator will be
damaged.
After the maintenance or repair check the right function of the butterfly valve and the tightness
of the pipe connections.
Also check the function of the accessories e.g. actuators, limit switches, etc.

5 Butterfly Valve
5.1 General
Before you are mount, adjust, start, operate or disassemble a butterfly valve you have to read
the
Safety advices
If you have nor read the safety advices until now, read this important advices now and turn back
to this point.
5.2 Corresponding use
Butterfly valves will be used to control and to cut off media flow.
It should only be used clean liquids and gases, on which the material of the butterfly valve will be
resistant. It should also be used for pulverised and pasterised media and pouring goods if it suited
to the butterfly valve. Pollution or using outside the nominal pressure range and/or the nominal
temperature range should causes damages on the butterfly valve especially on the seals.
5.3 Operation
The butterfly valve will be opened or closed by using a handle or actuator (option). The snap-in
handle of a hand actuated butterfly valve have to been snaped out during the operation. The disc
has 9 resp. 10 snap-in positions in which the lever could click in, to prevent an inadvertent mis-
place.
During the closing operation take care that there won`t be insert any objects or limbs into the
armature. Heavy injuries or damages will be the consequence. If it`s necessary you have to
install a protective device.
5.4 Mounting/Disassemble
The mechanical installation of the butterfly valves differs by the variants of the body. The wafer
type butterfly valve will be squeezed between to flanges and the lug type is able to be mounted
directly on flanges.

5.4.1 Mounting of the snap-in disc and the handle
At butterfly valves which will be actuated by hand the snap-in disc and the handle will be enclosed
the package. Before installing the butterfly valve you have to mount the handle and the snap-in
disc.
Observe the flow direction: the handle should point at the flow direction.
Remove the package and the protective devices (eg. caps and plugs). Take care that there will be
no parts of the package or other parts in the armature.
Clean up the pipes in which the butterfly valve will be mounted. Pollution could affect the safety in
operation and the duration of life of the butterfly valve.
Avoid stress in case of non align pipes.
The flanges have to be align parallel and centircally and must have carefully worked surfaces.

The butterfly valve will be squeezed between two flanges. The sealing takes places by the sleeve
of the butterfly valve other sealing compounds are not allowed. Take care that there won`t be
insert any rests of sealing compounds or other pollution into the armature.
The flanges would not been welded into the pipes if the armature is mounted. The increasing
temperatures will destroy the sleeve of the butterfly valve.
At polluted media we recommend to install the butterfly valve horizontally. In this case the lower
disc half have to close in the flow direction.

6 Maintenance
Before you maintain or shut down the butterfly valve you have to read the
Safety advice
If you have nor read the safety advices until now, read this important advices now and turn back
to this point.
On normal accounts the butterfly valve is maintenance free.In periodical turns the controlling of
the function and the tightness should happen:
• Check the tightness of stem seals
• Check the tightness of the sleeve
• Check the wear of the sleeve
At a leaky stem seal or sleeve you have to disassemble the butterfly valve and sent it back to the
manufacturer.
Don`t try to disassemble the sleeve of the butterfly vale by yourself. Heavy injuries or damages
could be the consequence.
In case of a defect of the valve make a contact to the supplier. The telephone number will be
found on the back or these operation and installation manual.
If you determinate that there is a demage to the valve switch off the device/ machine/ plant!
However before doing this, it is essential to refer to the
Safety advice.
