3 Details of Option Specification - D011 Specification : D011 Title: Packing 3/5 BJ SEALEVER : Grafoil packing for low emission made by Nippon Pillar Packing Co. LTD. This code does not need to be specified when LEV specifications are chosen in D301. The valve type, valve class, etc. determine the model number, "Type I" or "Type III". Refer to the supplemental explanation in D301 for details. BP P4519 Non-asbestos Used for gaseous fluids and PTFE low-emission types. BT P6118 (6 rings) + bushing Standard packing for waste incineration plants (Bushing shall be used. Collars shall not be used.) Note) Collar shall not be used for 20K cast steel valves. Instead, 6 rings + carbon bushing shall be used as is the case with 30K and 40K.
