1 Validity
This operating instruction is valid for the below listed ball valve series:
INTEC K100, K200, K400, K500, K600, K700, K800
Chemoball KH2F-CI
2 Predefined application and maximum load
Ball valves are valves with the function “open-closed”. They may only be used at the permitted pressure
and temperature for suitable media.
No safety can be guaranteed in the case of non-compliance of the allowed technical parameter
as pressure or temperature or if media are used which are not appropriate for the material
involved. The limits for pressure and temperature which are fixed in the respective technical
data sheets must be kept, otherwise the operation leads to overload, which the valves do not withstand.
The manufacturer doesn’t take any responsibility in this case. Any appearing water impact mustn’t exceed
the at most permitted pressure. Corresponding protection measures have to be carried out!
The specified connected load, as well as the mounting- and maintenance instruction (including the
instruction for actuators) must be met for valves with actuators
3 Type and design
Operation: Ball valves are operated with hand lever, gear box or with pneumatic or electric actuator.
Connection: Possible connections of ball valves: flange connection, threaded ends or welded ends (see
also the respective data sheet).
Special design: Please use a special design: at danger of an electrical charging, at contact with
oxygen, on request of the leakage inspection; at freezing danger, at fire risk or at increased
temperature requests.
4 Safety
4.1 Safety notes
•
The non-compliance of these safety notes leads to the loss of any claim for damages.
•
Beside our safety notes, national rules and regulations regarding the accident prevention, work-
ing-, operating and safety rules of the operator must be kept.
•
For the use of valves, the recognized rules of the technology must be kept e.g. standards, code
of practice, VDI- and VDE guide lines etc. Plants which must be observed are subject to decisive
laws, instructions and technical rules.
•
The operation of the ball valves should be carried out constantly and not too fast as jerky and fast
movement (water impact) can lead to an overload of the system. Standard value for the closing
time is t (sec.) = DN (mm).
•
Heating or cooling should not be carried out too fast to avoid an overload of the material caused
by an uneven distribution of the temperature.
•
At the use of pneumatic or electromechanical actuators, the maintenance personnel must safe-
guard themselves as there is the danger of cramping and squeezing. Protection facilities shall be
installed if necessary.
