Baker Hughes Consolidated 1900 Serie Manual De Instalación, Puesta En Marcha, Utilización Y Mantenimiento

The equipment that you have purchased was designed, manufactured and tested in accordance with the
essential safety requirements of the European Directive ATEX 2014/34/EU and PED 2014/68/EU.
Read these instructions carefully BEFORE installing, using or maintaining this pressure relief valve.
Products intended for installation in a potentially explosive gas or combustible dust atmosphere must:
a) be installed, put into service and maintained in compliance with national and local regulations and in
accordance with the recommendations contained in the relevant standards concerning potentially
explosive atmospheres.
b) be installed, put into service and maintained by qualified and competent professionals who have
undergone suitable training for instrumentation used in potentially explosive atmospheres.
Under certain operating conditions, the use of damaged pressure relief valves could cause a degradation of
the performances of the system, which may lead to personal injury or death.
Use only genuine spare parts, which are provided by the manufacturer, to guarantee that the products
comply with the essential safety requirements of the European Directives mentioned above.

under "INSTALLATION".
Note 1: IIC may be marked IIB or IIA- See product for marking & instructions for painted surfaces under "INSTALLATION"
Note 2: Dust protection is only available for the following valve models: 1900, 2900, 3900, 19000
Before proceeding with installation:
♦
Carefully unpack the pressure relief valve and check that it is not damaged. In the case of any
damage, notify the manufacturer.
♦
Check the compatibility of the equipment with the installation zone (Directive 99/92/EC).
♦
WARNING - Check that the maximum temperature of the fluid passing through the safety valve does not
exceed the maximum surface temperature of the temperature class T1 to T6 in the zone where the
equipment is installed and the limits recommended by the manufacturer (see catalogs available on our
Internet site at www.valves.bhge.com).
♦
WARNING - If applicable, verify that the maximum ambient temperature will not exceed the maximum
permitted ambient temperature indicated on the manufacturer's label of the limit switch mounted on
the safety valve (70°C). If no limit switch is present, the maximum ambient temperature is the maximum
temperature of the operating media.
♦
If the valve utilizes a bellows, ensure that the bonnet is vented to a safe area.

INSTALLATION
♦
WARNING - Potential Electrostatic charging hazard – only permitted on fixed installations, where
static built up can be controlled by this method:
• Painted surfaces – either limit paint thickness <0.2mm for Group IIC, 2mm for Group IIA or IIB,
or use a paint that can provide a dissipative coating, either meeting the <4kV breakdown
requirements or surface resistance testing.
If the safety valve is supplied with a limit switch, carry out the electrical connections of the limit switch after
checking that local conditions will allow. All instructions necessary for correct and safe installation of the limit
switch are available in the specific ATEX instructions attached to the instrument. These instructions can also
be accessed on the internet site www.honeywell.com.
In particular:
♦
Ensure the installation complies with the applicable regulations and standards, and observe the
instrument safety parameters.
♦
Connect the safety valve and electrical instruments to earth ground.
♦
Respect the polarities of the electrical connection.
♦
Use cable entries that comply with the zone and the protection mode of the instrument.
Before putting the safety valve into service, ensure the safety valve is correctly connected and all
manufacturer seals are present.
Use the safety valve within the temperature limits recommended by the manufacturer (see paragraph on
installation).
♦
Do not use the safety valve for any application other than that initially specified.
♦
Regularly check there is no leakage from the safety valve inlet or outlet.
♦
Respect the instructions for use of electrical apparatuses.
♦
Ensure the fluid does not carry particles likely to create a spark if the inside of the safety valve could
be considered as an ATEX zone.
Before carrying out maintenance work, ensure local conditions are suitable for the operations: Make sure
that suitable safety equipment and protection devices are available, taking into account the nature of
the operations and the zone where they are to be performed.
♦
Carry out the maintenance operations in compliance with the specific instructions for the product
concerned.
♦
Use only genuine spare parts, which are provided by the manufacturer.
♦
Remove deposits of combustible dust which may form on any exposed surfaces.
♦
To avoid the production of sparks due to electrostatic discharges, it will be advisable to follow the
instructions of the code of practice C L C / TR 50404. For example, the user will proceed with the
cleaning of the device and the plastic label, by means of a wet rag. For safety reasons, this
operation can be performed only when the local conditions are not potentially explosive.
Surveillance of equipment in potentially explosive atmospheres: comply with the regulations in force
(Directive 99/92/EC).
