Abstract
A drainage valve comprising a through hole, a seat around the through hole, a shutter comprising an end face and movable in a longitudinal direction between a first position in which the end face of the shutter is away from the seat and a second position in which the end face of the shutter is pressed against the seat and blocks the through hole, and an elastic element configured to keep the shutter in the first position. The shutter has a recess, emerging at its end face, configured to introduce therein a part of a tool in order to temporarily secure the part of the tool and the shutter in order to displace it in two directions longitudinally.
