A contactless filling device (10', 10") for contactless filling an article with a pourable product, having a temperature higher than room temperature, comprising: - a tank fillable with said pourable product at said temperature higher than said room temperature to perform a step of filling said article with said pourable product; - a first fluidic line extending between said tank and a pouring opening placed, in use and during the filling of said article, at a certain distance from a filling mouth of said article; - a first valve interposed along said first fluidic line, and displaceable between a relative open position in which it fluidically connects said tank and said pouring opening and a relative closed position in which it fluidically isolates said tank from said pouring opening; - a second fluidic line fluidically connected with said first fluidic line and with said tank and adapted to allow a continuous circulation of said pourable product at said temperature higher than said room temperature, when said first valve is in the relative said closed position; and - a second valve interposed along said second fluidic line, and displaceable between a relative open position in which it fluidically connects said tank and said first fluidic line through said second fluidic line, and a relative closed position in which it prevents the fluidic connection between said tank and said first fluidic line through said second fluidic line; said tank being fillable with a sanitising fluid to perform a step of sanitising the filling device (10', 10"); and by comprising: - a third fluidic line (25, 25") fluidically connected with said tank; - a closed element releasably fixable to a frame, which defines said first fluidic line, during said step of sanitising and so as to close said pouring opening and to fluidically connect said first and third fluidic line (12; 25, 25"); and - a third valve (42', 42") interposed along said third fluidic line (25, 25"), and displaceable between a relative open position in which it allows said sanitising fluid to flow along said third fluidic line (25, 25") from said first fluidic line towards said tank, and a relative closed position in which it prevents said sanitising fluid from flowing along said third fluidic line (25, 25"); characterized in that said second valve is displaceable between the relative said open and closed positions independently of the pressure difference, in use, within said second fluidic line between an upstream section and a downstream section of the second valve; said third valve (42', 42") being displaceable between said relative open and closed positions independently of the pressure difference, in use, within said third fluidic line (25, 25") between an upstream section and a downstream section (26, 26'') of said third valve (42', 42"). - a tank fillable with said pourable product at said temperature higher than said room temperature to perform a step of filling said article with said pourable product; - a first fluidic line extending between said tank and a pouring opening placed, in use and during the filling of said article, at a certain distance from a filling mouth of said article; - a first valve interposed along said first fluidic line, and displaceable between a relative open position in which it fluidically connects said tank and said pouring opening and a relative closed position in which it fluidically isolates said tank from said pouring opening; - a second fluidic line fluidically connected with said first fluidic line and with said tank and adapted to allow a continuous circulation of said pourable product at said temperature higher than said room temperature, when said first valve is in the relative said closed position; and - a second valve interposed along said second fluidic line, and displaceable between a relative open position in which it fluidically connects said tank and said first fluidic line through said second fluidic line, and a relative closed position in which it prevents the fluidic connection between said tank and said first fluidic line through said second fluidic line; said tank being fillable with a sanitising fluid to perform a step of sanitising the filling device (10', 10"); and by comprising: - a third fluidic line (25, 25") fluidically connected with said tank; - a closed element releasably fixable to a frame, which defines said first fluidic line, during said step of sanitising and so as to close said pouring opening and to fluidically connect said first and third fluidic line (12; 25, 25"); and - a third valve (42', 42") interposed along said third fluidic line (25, 25"), and displaceable between a relative open position in which it allows said sanitising fluid to flow along said third fluidic line (25, 25") from said first fluidic line towards said tank, and a relative closed position in which it prevents said sanitising fluid from flowing along said third fluidic line (25, 25"); characterized in that said second valve is displaceable between the relative said open and closed positions independently of the pressure difference, in use, within said second fluidic line between an upstream section and a downstream section of the second valve; said third valve (42', 42") being displaceable between said relative open and closed positions independently of the pressure difference, in use, within said third fluidic line (25, 25") between an upstream section and a downstream section (26, 26'') of said third valve (42', 42").
