A filling valve for a filling machine configured to fill a receptacle ; said filling valve comprising a flow channel having a first passage section configured to be fluidly connected with said receptacle ; said filling valve further comprising at least one shutter movably arranged within said flow channel and configured to be controlled, during a first operating mode in which said flow channel is fed with a first pourable product, at least in: - a resting position, in which said shutter delimits, together with said first passage section , a first maximum opening passage for said first pourable product, so as to allow a maximum flow rate of said first pourable product towards said receptacle and through said first maximum opening passage; - a closing position, in which said shutter is configured to sealingly cooperate with said first passage section , so as to prevent any fluidic connection between said first passage section and said receptacle ; and - at least one intermediate position, located between said resting position and said closing position, in which said shutter delimits, together with said first passage section , a respective intermediate opening passage, so as to allow a partial flow rate of said first pourable product towards said receptacle and through said intermediate opening passage; said flow channel having a second passage section configured to be fluidly connected with said first passage section and with said receptacle ; characterized in that said shutter is configured to be further controlled, during a second operating mode in which said flow channel is fed with a second pourable product different from said first pourable product and having solid particles in suspension, in: - said resting position, in which said shutter further delimits, together with said second passage section , a second maximum opening passage for said second pourable product, so as to allow a maximum flow rate of said second pourable product towards said receptacle and through said second maximum opening passage; and - a partial closing position, in which said shutter delimits, together with said second passage section , a restricted passage for said second pourable product, so as to allow a partial flow rate of said second pourable product towards said receptacle and through said restricted passage. - a resting position, in which said shutter delimits, together with said first passage section , a first maximum opening passage for said first pourable product, so as to allow a maximum flow rate of said first pourable product towards said receptacle and through said first maximum opening passage; - a closing position, in which said shutter is configured to sealingly cooperate with said first passage section , so as to prevent any fluidic connection between said first passage section and said receptacle ; and - at least one intermediate position, located between said resting position and said closing position, in which said shutter delimits, together with said first passage section , a respective intermediate opening passage, so as to allow a partial flow rate of said first pourable product towards said receptacle and through said intermediate opening passage; - said resting position, in which said shutter further delimits, together with said second passage section , a second maximum opening passage for said second pourable product, so as to allow a maximum flow rate of said second pourable product towards said receptacle and through said second maximum opening passage; and - a partial closing position, in which said shutter delimits, together with said second passage section , a restricted passage for said second pourable product, so as to allow a partial flow rate of said second pourable product towards said receptacle and through said restricted passage. <EOS>
