The present invention relates to a downhole inflow control valve for controlling the inflow of fluid from outside of a casing, such as from a reservoir or from an intermediate casing, and into the casing. The inflow control valve comprises a housing having an inlet and an outlet, a piston element sliding within the housing, as well as a face and at least one side abutting the housing and extending from the face towards the outlet of the housing. The face faces the inlet and has a piston hole allowing the fluid from the inlet to flow through the piston hole and out through the outlet, and a spring element is arranged between the housing and the piston.
