Unpacking; Installation - Flowserve Valtek MaxFlo 4 User Instructions

must be refitted. Apart from the operating instructions and the
obligatory accident prevention directives valid in the country of
use, all recognized regulations for safety and good engineering
practices must be followed.
a
WARNING: Before products are returned to Flowserve for
repair or service, Flowserve must be provided with a certificate
that confirms that the product has been decontaminated and is
clean. Flowserve will not accept deliveries if a certificate has not
been provided (a form can be obtained from Flowserve).
1.8 Storage
In most cases, Flowserve products are manufactured from
stainless steel. Products not manufactured from stainless steel
are provided with an epoxy resin coating. This means that
Flowerve products are well protected from corrosion. Neverthe-
less, Flowserve products must be stored adequately in a clean,
dry, environment. Plastic caps are fitted to protect the flange
faces and prevent the ingress of foreign materials. These caps
should not be removed until the valve is actually mounted into
the system.

2 Unpacking

2.1 While unpacking the valve, check the packing list against the
materials received. Lists describing the valve and accessories
are included in each shipping container.
2.2 When lifting the valve from shipping container, use straps
through the yoke legs. Take care to position lifting straps to
avoid damage to the tubing and mounted accessories.
c
DANGER: When lifting a valve be aware that the center of
gravity may be above the lifting point. Therefore, support must
be given to prevent the valve from rotating. Failure to do so
can cause serious injury or death and damage to the valve and
nearby equipment.
2.3 Contact you shipper immediately if there is shipping damage.
2.4 Should any problem arise, call your Flowserve representative.
c
DANGER: Before installation check the order number, serial
number, and/or the tag number to ensure that the valve and
actuator being installed are correct for the intended application.
a
CAUTION: Do not insulate extensions that are provided for
hot or cold services.

3 Installation

3.1 Before installing the valve, clean the pipeline of all contamina-
tion, carbon deposits, welding chips, and other foreign material.
Carefully clean gasket surfaces to ensure a tight seal. Pipelines
must be correctly aligned to ensure that the valve is not fitted
under tension.
3.2 Fire protection must be provided by the user.
3.3 Check the direction of fluid flow to ensure that the valve is
correctly installed. Flow direction is indicated by the arrow
attached to the body. All installation orientations for fitting the
valve into the pipeline are defined at the end of this manual.
c
DANGER: To avoid serious injury, keep hands, hair, clothing,
etc away from the plug and seat when the valve is working.
3.4 Whenever possible, the valve should be installed so that actuator
is in an upright position. Vertical installation of the actuator
permits easier valve maintenance.
3.5 Connect the air supply and instrument signal lines. Throttling
control valves are equipped with a valve positioner. Connections
are marked for the air supply and the instrument signal. Check
that the actuator and positioner can withstand the maximum air
supply from the network. The required air supply is indicated on a
sticker located on the actuator. An air regulator will be necessary
in certain cases in order to limit the supply pressure. A filter is
recommended unless the air supplied is exceptionally clean and
dry (air quality without humidity, oil, or dust as per IEC 770 and
ISA-7.0.01). All connections must be completely tight.
a
CAUTION: On valves equipped with air filters, the air filter
must point down to perform properly.
3.6 Use the bolts indicated in table I for installing the valve in the
pipeline, and then tighten alternately according to good practice.
The user must in all cases confirm the capacity of the bolts to
ensure a sufficiently tight gasket seal for the expected service
conditions.
3.7 Be sure to provide proper overhead clearance for the actuator to
allow for disassembly of the actuator from the valve body. Refer
to the appropriate to the MaxFlo 4 Technical Bulletin for proper
clearances. The MaxFlo 4 Technical Bulletin is available at www.
flowserve.com.
