Director, Pipeline Safety Regulations\nMaterials Transportation Bureau\nDept. of Transportation\nWashington, DC 20590\nDear Mr. Beam:\nOur company is a manufacturer of non-lubricated plug valves. We have, in the past two years,\nbegun marketing these valves in the gas distribution industry on a wide variety of applications.\nRecently, one of our sales engineers was visiting with a prospective gas utility client who called\nour attention to Title 49, Federal Code, Para. 192.363, subparagraph (b), which indicates that\nsoft-seated valves should not be in a service line if the valve's performance would be affected by\nanticipated heat.\nOur prospective client claims he cannot use our product because the soft seat \"may be destroyed\nin a fire.\" My question is to clarify the phrase, \"anticipated heat.\" Is this spec referring to a fire,\nor simply hot gas flowing under normal operating conditions? Please send a written clarification\nof this spec to:\nAllan W. McKee - Petroleum Market Mgr.\nThe Duriron Co., Inc. - Valve Division\nP.O.
