The “►” marks indicate the most typical selection for each specification.
*1: Users must consider the characteristics of selected wetted parts material and influence of process fluids. Specifying inappropriate
materials has the potential to cause serious damage to human body and plant facilities resulted from an unexpected leak of the
corrosive process fluids.
