Optional codes
/ Optional specification
The “►” marks indicate the most typical selection for each specification.
*1: Users must consider the characteristics of selected wetted parts material and the influence of process fluids. The use of
inappropriate materials can result in the leakage of corrosive process fluids and cause injury to personnel and/or damage to plant
facilities. It is also possible that the diaphragm itself can be damaged and that material from the broken diaphragm and the fill fluid
can contaminate the user’s process fluids.
Be very careful with highly corrosive process fluids such as hydrochloric acid, sulfuric acid, hydrogen sulfide, sodium hypochlorite,
and high-temperature steam (150°C [302°F] or above). Contact Yokogawa for detailed information of the wetted parts material.
