WebFeb 22, 2010 · The FCI 70-2 (Fluid controls institute Inc. intially ASME B16.104) Leakage classes are specified for an ESD ball valve and a Pipeline MOV Gate valve having composite seats. The composite seats are a metal + soft sealing combination. Class VI and V are specified for the ESD and MOV valves respectively. WebThe FCI Control Valve and Regulator Section notes that FCI 70-2 has been intended to apply to control valve seat leakage. If line isolation and/or absolute tight shut-off is a normal expectation of the valve application, the FCI Control Valve and Regulator Sections recommend specifying another standard, such as API 598, "Valve Test and Inspection."
