Improved device for the installation of sprue-type valves, of the type consisting of an elastic bushing that is introduced under pressure in a hole of the water conduit of the trough and is retained in said hole by means of a lower stop flange against the conduit and of an upper flange that is applied on the inner edge of said hole, characterized essentially by the fact of comprising a flange formed in the body of the valve in an area near its upper end and resting on the rim of the bushing, with what is obtained a stop effect that prevents the valve body from sliding through the bushing and comes out due to pressures, thrusts, weight and other causes tending to cause axial displacement of the valve body.
