An arrangement for spraying a fluid to a piece of material, such as a web or strip, has a chamber through which the material runs, and an applicator (15) which is configured to spray the fluid on the material. The applicator includes at least a first and a second valve (16, 16a, 16b, 16c) arranged within the chamber, each valve having a longitudinal axis, and each valve comprising a spray nozzle (17, 17a, 17b, 17c). Each spray nozzle has an elongated opening extending along an axis. The longitudinal axis of the valve and the axis of the corresponding nozzle span a plane and the at least said first valve and said second valve are arranged spaced on a common axis (CA) running through a center point of each valve. The plane is inclined in relation to the common axis.
