inappropriate materials can result in the leakage of corrosive process uids 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 ll uid
can contaminate the user’s process uids.
Be very careful with highly corrosive process uids such as hydrochloric acid, sulfuric acid, hydrogen sulde, sodium hypochlorite,
and high-temperature steam (150˚C [302˚F] or above). Contact Yokogawa for detailed information of the wetted parts material.
The ‘#’marks indicate the construction materials conform to NACE material recommendations per MR01-75. For the use of 316
SST material, there may be certain limitations for pressure and temperature. Please refer to NACE standards for details
