Installation, Operation & Maintenance
2.4.4 Body gaskets and packing
Check the sealing elements for tightness. If they are not
leakproof, tighten with the valve depressurised. If tightness
is not achieved, a new body gaskets and packing must be
used.
The sealing elements must be replaced with the valve
depressurised, the requirements of section 1.2 + 2.8 of this
operating manual must be met.
2.5 Faults and Fault Rectification
•
Determine and define the type of problem.
•
If the problem is caused by a heavy leak, the leak spot
should be localised if possible.
•
Inform KROMBACH. (See Warranty section 2.9)
2.6 Accessories
2.6.1 Final Position Switch
The installed final position switches must be connected
according to the respective circuit diagram and checked for
correct adjustment.
2.6.2 Locking Fixtures
To prevent the valve being actuated unintentionally, which
could lead to danger, locking and catch fixtures are available
from the manufacturer.
2.6.3 Special Accessories and Versions
Additional specifications must be heeded for valves with
special accessories or for special versions.
2.6.4 Valves with Gear and/or Actuator
Special mounting, maintenance and operating instructions
from the manufacturer are valid for gears and/or drives!
Please contact KROMBACH if you have any queries.
Ball valves with gear, electric/pneumatic setting drive
are installed in the normal installation position: Stem
vertically upright (drive at the top) in the pipeline.
This installation position must be observed!
KROMBACH must be consulted if other installation posi-
tions are required!
•
The direction of rotation
(clockwise = CLOSE;
anti-clockwise = OPEN)
remains the same whether the valve is actuated by
means of the gear handwheel or the electric/pneumatic
actuating drive!
The connection of electric cables may only be carried out by
specialised staff.
Applicable regulations, in particular VDE 0100 and VDE 0165
(explosion protection) must be heeded.
2.6.5 Retrofitting Actuators
The very wide range of operating conditions and possible
installation positions must be taken into consideration in
particular when retrofitting drives.
KROMBACH must always be consulted in such cases!
2.7 Repairs
Repairs and service work on valves may only be carried out
by the manufacturer or trained staff, see also section 1.2.
2.7.1 Repairs at the Manufacturer's
•
Due to increased efforts to protect the environment and
the health of our employees, we need to know from you
which materials the ball valves to be repaired by our
employees have been in contact with.
•
Our service technicians may not do any work without
this contamination declaration.
•
To avoid unnecessary expenditure and delay for you and
us, we require your contamination declaration together
with the order and shipping papers in the event of
repair or replacement work (form is attached or can be
requested from us).
2.7.2 Repairs at the Operator's
If the valve cannot be repaired at the manufacturer's, this
work should be carried out by a service fitter or by trained
operator staff. Only original spare parts may be used for this.
