2 Health and Safety
The product/system must not be operated beyond the parameters specified for the
application. If there is any doubt as to the suitability of the product/system for the
application intended, contact Flowserve for advice, quoting the serial number.
When installing, operating or maintaining valves:
a) Complete a risk assessment and eliminate or reduce hazards to an acceptable
level.
b) Work in accordance with safe systems of work.
c) Observe all site health and safety rules.
d) Wear all the necessary personal protective equipment (PPE).
e) Never remove or maintain a valve or joint unless the line has been fully de-
pressurised, drained, and where necessary, purged of toxic / explosive /
flammable media. Always operate the valve to the open position to ensure that
no trapped pressure exists within the cavity.
f) Never handle valves that have been used on harmful substances unless they
have been completely decontaminated and certified safe to handle.
g) Never use a valve on an application which exceeds its prescribed operating
parameters. Refer to Flowserve Flow Control technical sales for performance
curves for further information.
h) Never modify or alter valves unless the manufacturer has been consulted or
recommends such changes.
i) Wrenches are only designed to operate the valves and must not be used to
carry them as it may result in operator injury or damage to the valve stem and
sealing.
j) Use appropriate lifting methods and equipment when installing, maintaining and
removing the product. Ensure that the valve is correctly supported in its operating
location.
k) The valve must be installed in a system design to prevent excessive forces on the
flanges and connectors.
l) Consult Flowserve Flow Control technical sales before equipment is installed in
areas subject to seismic activity or extreme climates.
m) The valve should be protected by other devices to prevent over-pressurisation,
e.g. increased pressure caused by external fire.
n) It is the end user’s responsibility to ensure compatibility of the media with the
materials of construction of the product. The integrity of the valve may be
affected by the effects of corrosion and erosion.
o) If the processes or environments that the valve is used in are likely to cause
temperatures (high or low) that may cause injury to personnel if touched,
adequate protection must be fitted on the valve.
p) If the valve is to be used for unstable gas applications, ensure that the
operational parameters as indicated on the product identification plate cannot
be exceeded.
