1. Special heat treating required.
2. Derating is not required for CL300 valves. Derating may be required for valves rated at CL600. Contact your Emerson Process Management sales office for assistance in determining the
derating of valves when these body-to-bonnet bolting materials are used.
3. WCC is limited to -29_C(-20_F).
