3.6
Safety lnstructions for Maintenance, Inspection and Installation work
3.6.1
General
On an actuated valve the operating instructions of the valve must be strictly followed as well as those of the operating
instructions of the actuators, the limit switch or automation boxes.
The user is responsible for ensuring that all maintenance, inspection and installation work is carried out by authorized,
adequately qualified staff who are thoroughly familiar with this instruction manual.
Any work on a valve may only be performed when the valve is un-pressurized and has cooled down to 60°C.
Any work on actuated valves may only be done after that the actuator has been disconnected from its energy supply.
The procedure described in the operating instructions to shut down the actuator must be observed. Valves in contact with
hazardous media must be decontaminated. Immediately following completion of the work, all safety relevant and protective
devices must be reinstalled and/or re-enabled. Prior to recommissioning, refer to the points listed under section 7
Commissioning.
3.6.2
End of line installation
Please refer to §5.6
NB: A valve fitted at the end of a pipe with a blind flange downstream is not to be considered as an end of pipe service.
3.6.3 Locking device
Please refer to §5.7
This option could be used in order to lock the valve in full open or full close position and to remove the actuator from the valve.
Do not
operate the valve when the locking device is engaged.
3.7 Unauthorized Modification and Manufacturing of Spare Parts
The equipment shall not be altered or modified in any way prior to consultation with the manufacturer. Genuine spare parts
and accessories authorized by the manufacturer will ensure operational safety. The manufacturer cannot be held responsible
for damage resulting from the use of non-genuine parts or accessories.
3.8
Inadmissible Modes of Operation
Operational safety and reliability of the valve supplied is only warranted for its designated use as defined in section 2 ”General”
of the operating instructions. The limits stated in the technical documentation must not be exceeded under any circumstances.
4.
Transport and Interim Storage
4.1
Transport
The valves in the as-supplied condition are ready for operation.
ATTENTION For transport and storage, the valves must always be maintained in the semi-closed position and be packed in
cardboard, crate or case with suitable protection (desiccant, thermowelded barrier).
ATTENTION To prevent damage, do not hang the valve by its handle or disc or actuator.After delivery or prior to installation,
the valve should be checked for damage during transit.
4.2
Interim Storage
The valves must be stored in such a way that correct operation is assured even after prolonged storage.
This comprises:
- Storing at 5° from the closed position
- Suitable measures against contamination, frost and corrosion (e.g. by using thermowelded plastic bags with desiccant,
protection caps and plugs onto threaded holes)
- Temperature from +5°C to +50°C
- To protect the seals ( elastomer parts) against direct sunlight and/or UV
- Dry and aerated place, clean, without any contact with sand or other debris
