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. |
