A check and foot valve, essentially characterized by comprising a spheroidal body, provided with two tubular necks diametrically projected, all hollow; whose body internally carries a plate. Transverse, which forms a single piece with it, and in which there are a plurality of grooves and an axial passage, which serves as a housing for a screw through which an elastic membrane, cast directly on the aforementioned screw, is fixed to ensure its total adhesion, whereupon, the mentioned membrane supports on one of its faces on the support plate, which determines that the passage of liquid or fluid through the valve, is verified only in the direction plate-membrane, by bending this.
