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.
