 Considerations
NOTICE
Certain valve constructions are uni-directional A flow arrow
will indicate the flow direction Care should be take when
installing the valve to ensure these special constructions
The valve may be fitted in any position on the pipeline
Before installing the valves the pipes must be flushed clean of
dirt burrs and welding residues or the seats and ball surface will
be damaged
If for any reason the valve is installed prior to flushing of the
piping system the valve must remain in the full open position
until the piping system has been fully flushed clean of debris
Ensure the adjoining pipe on each end of the valve is aligned to
prevent external piping loads Piping misalignment may cause
excessive external loads on the valve resulting in body joint leaks
For hydrostatic testing of the piping system the valves must be
placed in the full or half open position prior to pressurizing the
system
NOTICE
Hydrostatic system testing with the valve in the closed position
may result in damage to the valve seats aecting their ability
to create a proper seal
Failure to implement the installation and testing instructions
as outlined resulting in a valve failure will void the warranty
coverage of the product
 Actuator Installation
 It is recommended that the actuator package is installed to
allow sucient space for removal
 It is recommended to install the actuator package with
the valve stem in the upright position If stem is in other
than vertical position actuator package weight support is
recommended to avoid any possibility of side load during
operation
 It is recommended to avoid installing the actuator package
where the actuator or accessories are in contact with the
pipeline or pipeline structure
WARNING
Keep hands and other body parts clear of the valve flow port
and other rotating machinery
 Prior to putting the valve into service cycle actuator to
ensure valve actuator and accessories operate properly
