A microvalve with a normally closed state includes a membrane (80), an actuation means (100) for controllable deformation of the membrane (80) as well as a valve shutter (180) deformable by the controllable deformation of the membrane (80). The valve shutter (180) at least partially opposes the membrane (80) and rests, in a first position in the normally closed state of the valve, along a sealing lip (130) arranged between the valve shutter (180) and the membrane. The sealing lip (130) is arranged such that an outlet of the valve, which outlet is in fluid communication with an interrupted section of the sealing lip (130), is sealed against an input channel (170) bordering on the valve shutter (180). In addition, the valve shutter is moldable into a second position so as to bring the outlet (140) into fluidic communication with the input channel (170) in an open state of the valve.
