1.3 Notes on possible property damage
NOTICE
!
Incorrect control performance due to a combination of trim parts that do not match
each other.
The trim parts (seat, plug, anti-rotation xture and body gasket) are matched to exactly
t each other. The trim parts are delivered together and marked accordingly (see the
'Markings on the device' section).
Î Only install matching trim parts.
Risk of valve damage due to contamination (e.g. solid particles) in the pipeline.
The plant operator is responsible for cleaning the pipelines in the plant.
Î Flush the pipelines before start-up.
Risk of valve damage due to unsuitable medium properties.
The valve is designed for a process medium with dened properties.
Î Only use the process medium specied for sizing.
Risk of leakage and valve damage due to excessively high or low tightening
torques.
Observe the specied torques when tightening control valve components. Excessive
tightening torques lead to parts wearing out more quickly. Parts that are too loose may
cause leakage.
Î Observe the specied tightening torques (uAB0100).
Risk of valve damage due to the use of unsuitable tools.
Certain tools are required to work on the valve.
Î Only use tools approved by SAMSON (uAB0100).
Risk of valve damage due to the use of unsuitable lubricants.
The lubricants to be used depend on the valve material. Unsuitable lubricants may cor-
rode and damage surfaces.
Î Only use lubricants approved by SAMSON (uAB0100).
