1.3 Notes on possible property damage
NOTICE
!
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 dened properties.
Î Only use the process medium specied for sizing.
Risk of leakage and valve damage due to excessively high or low tightening
torques.
Observe the specied 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 specied tightening torques (uAB0100).
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 (uAB0100).
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 (uAB0100).
Risk of the process medium being contaminated through the use of unsuitable lubri-
cants and/or contaminated tools and components.
Î If necessary, keep the valve and the tools used free from solvents and grease.
Î Make sure that only suitable lubricants are used.
