4. Regulation Use
Any use of the Butterfly Valves with Pneumatic Actuator, model: KLP, which
exceeds the manufacturer’s specifications, may invalidate its warranty. Therefore,
any resulting damage is not the responsibility of the manufacturer. The user
assumes all risk for such usage.
Ball valves will be used to cut off medium flow.
It should only be used for clean liquids and gases, on which the material of the
ball valve is resistant. Pollution or exceeding the nominal pressure range and/or
the nominal temperature range may lead into damages on the armature
especially on the seals.
5. Safety Regulation
Depending on the technical circumstances under which the armatures and valves
are mounted, adjusted and commissioned, you possibly must take into account
particular safety aspects in each case!
If, for example, a pneumatic actuator 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 advice on hazards in the following descriptions
which are not relevant to you.
Please observe (only) the advice which applies to your situation!

5.1 Personal Advice
5.1.1 Safety Advice for Mounting
We wish to point out expressly that the mounting, adjusting
and, with accessories, the pneumatic and electrical installation
of the armatures and valves must be carried out by trained
specialist personnel having mechanical, pneumatical and
electrical knowledge!
 Secure that the machine / plant complies with to the Machinery Directive after
the mounting and installing of the armatures and 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 the devices
/ machines / plant will cause potential danger.
 If appropriate, in the event of a fault in the armature / valve (in a plant which is
in operation) inform the shift foreman / 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 /machines / 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 buttons/ safety valves, etc)!

5.1.2 Safety Advice for Adjustment / Starting
As a result of the starting (pneumatic, electric or by hand) of the
armatures and 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 that 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.!
 After completing the adjustment check the correct function and should the
occasion arise the position of the slide / valve / flap.
 Check the function of the limit switches (option)!
 Check, whether the slide / valve / flap will be closed totally, if the control
signals the appropriate limit stop!
 Through suitable measures, prevent actuating links from being trapped by
moving actuating elements!
 Check for correct functioning 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 described in this documentation!
Adjustments of switched on (ready to operate) armatures and
valves with options (e.g. actuators, drives, limit switches)
presents the risk that live parts (230 V AC~) can be touched!
Therefore, the adjustments must be carried out only by an
electrician or a person having adequate training, who is aware
of the potential hazard!

5.1.3 Safety Advice for Maintaining / Repairing
Do not carry out any maintenance / repairs if the armature / valve will be
under pressure.
Before disassembling of an armature or valve some essential points should be
clarified:
 Will the armature/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 disassembly?
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!
Observe that some valves / armatures are able to contain the pressured
medium e.g. the ball in the ball valve. You have to relieve the pressure in
the pipes in which the armature/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
armature/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 armature/valve contact the supplier.
If you ascertain a damage of the armature/valve, isolate the device from the
mains. Please observe the safety advices.
Do not mount, start or adjust the armature/valve if it would cause damage
to itself, the pipes or a mounted actuator.
After completing the maintenance or repair, check for correct functioning of the
armature/valve and the tightness of the pipe connections.
Also check the functioning of the accessories e.g. actuators, limit switches, etc.

5.2 Device Safety
The armatures/valves
 are quality products which are produced in accordance to the recognised
industrial regulations.
 left the manufacturer’s work in a perfect safety condition.
In order to maintain this condition, as installer / user you must carry out
your task in accordance with the description in these instructions,
technically correctly and with the greatest possible precision.
We assume, as a trained specialist you are having mechanical and electrical
knowledge! Satisfy yourself that the armatures/vales will only be used within their
admissible limiting value (see the technical data).
The armatures/valves must be used only for purposes corresponding to
their design! The armatures/valves must be used within the values
specified in the technical data! The operating of the armature/valve outside
the nominal temperature range could destroy the sealings and the bearings.
The operating of the armatures/valves outside the nominal pressure range
could destroy the inner parts and the body.
Never remove a cap or any other component part if the
armature/valve is under pressure.
Do not mount, put into operation or adjust the armature/valve if pipes or a
mounted actuator are damaged.
After finishing the assembling and adjustments check for proper functioning of the
armature/valve and the tightness of the pipe connections.
Also check the functioning of the accessories e.g. actuators, limit switches, etc.

6. Pneumatical Installation
The installation of the air supply has to be carried out with great
care. Especially the threaded connection, fittings and sealings
have to be clean and free of contaminates. Contamination, which
remains inside the actuator, will cause advanced wear or damage
to the sealings and treads.
The pneumatic actuator ED/EE is available in two operation variants:
 function double-acting, or
 function single-acting with spring return
Use only adequate hoses and hose connectors for your application.
While passing the hoses please ensure, that they will not be
creased, squeezed or sheared or that the hose will not be laid
over sharp edges. Also take care that there will be no pressure
or traction on the hose.
Pass the hoses to its Basic position, if so possible, within conduits or cable ducts.
As an alternative to the shown variant the control of the actuator could be carried
out by a directly mounted pilot valve.

6.1 Function “Double-Acting“
 Remove the protection caps from the ports “P1“ and “P2“.
 Screw suitable pneumatic fittings (e.g. Art. C12xx or R12xx) into the ports “P1“
and “P2“ and tighten the fittings.
 Insert a hose into the fitting at port “P1“ which will supply the actuator with
compressed air during the opening operation.
 Insert a hose into the fitting at port “P2“ which will supply the actuator with
compressed air during the closing operation.
 Tighten the hoses in the fittings at port “P1“and “P2“.
 Check the tightness of all connections.
