NOTES:

1. For “Firesafe Trim” assemblies Graphite Impregnated Carbon Packing is substituted for
Trunnion Seal. Also, Bonnet Gasket and Trunnion Gasket utilize a Stainless Steel/Grafoil Spiral Wound Gasket,
rather than an O-ring. All other materials are as specified in the Assembly Part Number Suffix.
2. Body, Bonnet and Adapters are available in Stainless Steel (ASTM A 352 Gr. CF8M) upon request.
