KTM HINDLE
ULTRA-SEAL SERIES 300 TWO PIECE CRYOGENIC
INSTALLATION AND MAINTENANCE INSTRUCTIONS
Before installation these instructions must be fully read and understood
VCIOM-03759-EN 15/06
1 STORAGE / PROTECTION / SELECTION
Storage
When valves are to be stored for some time
before being fitted, storage should be in the
original delivery crates with any waterproof
lining and/or desiccant remaining in place.
Storage should be off the ground in a clean, dry,
indoor area. If storage is for a period exceeding
six months the desiccant bags (if supplied)
should be changed at this interval.
Protection
KTM Hindle valves are delivered with protection
according to customer's specification, or in
accordance with the Quality Assurance Manual,
to protect the valve seats and closure member
from damage. Wrapping and/or covers should
be left in place until immediately before fitting
to the pipe.
Selection
Ensure the valve’s materials of construction
and pressure/temperature limits shown
on the identification plate are suitable for
the process fluid and conditions. If in doubt
contact KTM Hindle.
3 OPERATION AND ROUTINE MAINTENANCE
!! Read all warning labels fitted to the valve
before operation or maintenance !!
Scope
KTM Hindle Series 300 Cryogenic Valves both
manual and actuated.
Operation
All standard manually operated valves are
‘clockwise to close’. The closed position is
indicated by either the handlever or indicator
arrow being at 90° to the pipe/valve bore axis.
Routine maintenance
No routine maintenance is required other
than periodic inspection to ensure satisfactory
operation and sealing.
Any sign of leakage from the gland packing
should be addressed immediately by
depressurizing the valve and tightening the
gland nut. If no further adjustment is possible,
or if seat or joint leakage is suspected, the valve
will require a complete overhaul.
2 INSTALLATION
WARNING!
For Safety reasons, it is important to take the
following precautions before you start work
on the valve:
1. Personnel making any adjustments to the
valves should utilize equipment and clothing
normally used to work with the process
where the valve is installed.
2. The line must be depressurized, drained
and vented before installing the valve.
3. Handling and installation of all valves,
operators and actuators must be carried
out by personnel trained in all aspects
of installation and manual/mechanical
handling techniques.
4. Ensure the valve pressure/temperature
limitations marked on the identification label
are above or equal to service conditions.
This should be carried out after
depressurisation and in accordance with
KTM Hindle Maintenance Instructions. Only
KTM Hindle spares should be used.
Spare parts
KTM Hindle valves are identified by a figure
number, stamped on the identification plate,
located on the valve body flange. This reference
should be quoted in respect of any after sales
queries, spare parts or repair enquiries/orders.
1. KTM Hindle Series 300 low temperature
valves for -50°C service and above are
bi-directional as standard and may be
fitted in either direction. Valves for service
below -50°C are uni-directional and
should be fitted with the body seat located
downstream.
2. Installation of cryogenic valves should
be carried out with the extension bonnet
displaced within 45° of vertical.
3. Remove protective covers from valve faces.
4. Ensure that mating flanges and gaskets are
clean and undamaged.
5. Possibility of abrasive particles (weld slag,
sand etc.) within the piping system could
damage valve seating/ball. The system will
need to be flushed clean.
6. Ensure mating pipe flanges are aligned
correctly. Bolting should be easily inserted
through mating flange holes.
7. Fit the valve into pipework ensuring easy
access of the lever/handwheel.
8. Tighten the flange bolts in a diagonal pattern.
