- 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.
- Cast version of 316 SST. Equivalent to SCS14A.
- Hastelloy C-276 or ASTM N10276.
- Not applicable for output signal code F.
