Abstract

The present invention pertains to a device for applying fluid material on a substrate, with a supply canal for supplying material from a source of material, a main body with an outlet canal which communicates with the supply canal and ends in an outlet opening for delivering the material. A valve assembly located in the main body interrupts the flow of material in the outlet canal, which has a valve seat and a valve body which can move relative to the valve seat, as well as a tensioning device which pre-tensions the valve body in a closed or open position. A drive unit moves the valve body between a closed position which interrupts the flow of material and an open position which releases the flow of material. The supply canal is connected to the outlet canal in a lower part of the main body which is preferably close to the outlet opening, and the tensioning device for pre-tensioning the valve body is located in the lower area of the main body.
