A poppet valve (110) arrangement is described such as can be used in a pipe (240F, 240M) terminal and/or flow (1, 2) coupler, said arrangement comprising: a poppet valve (110) comprising a biasing device; and a housing (120, 220F, 220M, 820F) comprising an inlet, an outlet and a flow (1, 2) channel (130) configured to provide fluid communication between said inlet and said outlet when said poppet valve (110) is open; wherein: said fluid communication provided by said flow (1, 2) channel (130) is blocked by the poppet valve (110) under action of said biasing device when the poppet valve (110) is closed; and the poppet valve (110) is supported with respect to the housing (120, 220F, 220M, 820F) by a channel (130) splitter that radially sections the flow (1, 2) channel (130) into a sectioned substantially annular flow (1, 2) channel (130) portion around the poppet valve (110). L'invention décrit un agencement de soupape-champignon (110) tel que celui pouvant être utilisé dans un embout de tuyau (240F, 240M) et/ou un organe d'accouplement d'écoulement (1, 2), ledit agencement comprenant : une soupape-champignon (110) comprenant un dispositif de sollicitation; et un boîtier (120, 220F, 220M, 820F) comprenant une orifice d'entrée, un orifice de sortie et un canal (130) d'écoulement (1, 2) configuré pour créer une communication fluidique entre ledit orifice d'entrée et ledit orifice de sortie lorsque ladite soupape-champignon (110) est ouverte; dans lequel : ladite communication fluidique établie par ledit canal (130) d'écoulement (1, 2) est bloquée par la soupape-champignon (110) sous l'action dudit dispositif de sollicitation lorsque la soupape-champignon (110) est fermée; et la soupape-champignon (110) est supportée par rapport au boîtier (120, 220F, 220M, 820F) par un séparateur de canal (130) qui divise radialement le canal (130) d'écoulement (1, 2) en une partie de canal (130) d'écoulement (1, 2) sensiblement annulaire divisée autour de la soupape-champignon (110).
