General Information
1.1. Usage
The following instructions are designed to assist in unpacking, installing and performing maintenance
as required on Flowserve products. Product users and maintenance personnel should thoroughly
review this bulletin prior to unpacking, installing, operating, or performing any maintenance. In most
cases, Flowserve valves, actuators and accessories are designed for specific applications (e.g. with
regard to medium, pressure, temperature). For this reason they should not be used in other applications without first contacting the manufacturer. The product Installation, Operation, and Maintenance
Instructions provides important additional safety information.
1.2. Applicability
The following instructions are applicable to the maintenance and installation of Mark 10 Survivor
control valves. These instructions cannot claim to cover all details of all possible product variations,
nor in particular can they provide information for every possible example of installation, operation or
maintenance. This means that the instructions normally include only the directions to be followed by
qualified personnel where the product is being used for its defined purpose. If there are any uncertainties in this respect particularly in the event of missing product-related information, clarification must
be obtained via the appropriate Flowserve sales office. All Flowserve User Manuals are available at
www.flowserve.com.
1.3. Terms Concerning Safety
The safety terms DANGER, WARNING, CAUTION and NOTE are used in these instructions to highlight
particular dangers and/or to provide additional information on aspects that may not be readily
apparent.

DANGER: b indicates that death, severe personal injury and/or substantial property damage will
occur if proper precautions are not taken.
WARNING: c indicates that death, severe personal injury and/or substantial property damage can
occur if proper precautions are not taken.

CAUTION: a indicates that minor personal injury and/ or property damage can occur if proper
precautions are not taken.
NOTE: indicates and provides additional technical information, which may not be very obvious even
to qualified personnel.
Compliance with other, not particularly emphasized notes, with regard to transport, assembly,
operation and maintenance and with regard to technical documentation (e.g. in the operating instruction, product documentation or on the product itself) is essential, in order to avoid faults, which in
themselves might directly or indirectly cause severe personal injury or property damage.
1.4. Protective Clothing
Flowserve products are often used in problematic applications (e.g. extremely high pressures,
dangerous, toxic or corrosive mediums). When performing service, inspection or repair operations
always ensure that the valve and actuator are depressurized and that the valve has been cleaned and is
free from harmful substances. In such cases pay particular attention to personal protection (protective
clothing, gloves, glasses, etc.).
1.5. Qualified Personnel
Qualified personnel are people who, on account of their training, experience and instruction and their
knowledge of relevant standards, specifications, accident prevention regulations and operating conditions, have been authorized by those responsible for the safety of the plant to perform the necessary
work and who can recognize and avoid possible dangers.
1.6. Spare Parts
Use only Flowserve original spare parts. Flowserve cannot accept responsibility for any damages that
occur from using spare parts or fastening materials from other manufactures. If Flowserve products
(especially sealing materials) have been on store for long periods, check for corrosion or deterioration before using these products.
1.7. Service / Repair
To avoid possible injury to personnel or damage to products, safety terms must be strictly adhered
to. Modifying this product, substituting non-factory parts, or using maintenance procedures other
than outlined in this instruction could drastically affect performance and be hazardous to personnel
and equipment, and may void existing warranties. Between actuator and valve there are moving parts.
To avoid injury, Flowserve provides pinch-point-protection in the form of cover plates, especially
where side-mounted positioners are fitted. If these plates are removed for inspection, service or
repair, special attention is required. After completing work the cover plates 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.
WARNING: c Before products are returned to Flowserve for repair or service, Flowserve must
be provided with a certificate which 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 Flowserve
products are well protected from corrosion. Nevertheless, Flowserve products must be stored
adequately in a clean, dry environment. Plastic caps are fitted to protect the flange faces by
preventing the ingress of foreign materials. These caps should not be removed until the valve is
actually mounted into the system.
1.9. Unpacking
While unpacking the valve, check the packing list against the materials received. Lists describing the
valve and accessories are in each shipping container.
When lifting the valve from the shipping container, use straps through the yoke legs, or the lifting
lugs attached to the yoke bolting. Take care to position lifting straps to avoid damage to the tubing
and mounted accessories.
WARNING: c 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 to personnel and damage to the valve or nearby equipment.
Contact your shipper immediately if there is shipping damage.
Should any problem arise, call your Flowserve representative.
