A flange globe valve is a valve where the closure part (valve flap) moves along the centerline of the valve seat. According to this form of movement of the valve flap, the change of the valve seat port is proportional to the stroke of valve flap. Because the stroke of opening or closing of the valve stem of this type of valve is relatively short, and has a very reliable cut-off function, and because the change of the seat port is proportional to the stroke of the flap, making flange globe valve ideal for regulating flow. Therefore, the flange globe valve is ideal for shutting-off or regulating and throttling.
