Model and Suffix Codes
Bolts and nuts material: A - SCM435: 3 MPa {30 kgf/cm?} (A capsule); 14 MPa {140 kgf/cm?}
Pressure test/Leak test Certificate7: /T02 - Test Pressure: 14 MPa{140 kgf/cm?}8; Nitrogen(N2) Gas9
NOTE:
The marks indicate the most typical selection for each specification.
The # marks indicate the construction materials conform to NACE material recommendations per MR01-75. For the use of SUS316 material, there may be certain limitations for pressure and temperature. Please refer to NACE standards for details.
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.
Indicates high pressure side cover flange and process connector material. Material of low pressure side cover flange (open to atmosphere) is SCS14A.
Diaphragm material is Hastelloy C-276 or ASTM N10276. Other capsule wetted parts materials are SUSF316L, SUS316L or ASTM grade 316L.
SUS316 or ASTM grade 316.
If necessary, specify Mounting bracket code A, B or J.
Applicable for Process connection code 0 and 5.
The unit on the certificate is always MPa regardless of selection of option code D1, D3, or D4.
Applicable for Capsule code B.
Pure nitrogen gas is used for oil-prohibited use (Optional code K1, K2, K5, and K6).
The unit of MWP (Max. working pressure) on the name plate of a housing is the same unit as specified by Option code D1, D3 and D4.
