Abstract
An irrigation valve adapted to be placed in an inlet pipe for irrigation liquid under a cultivation table for potted plants or the like. The irrigation valve includes a valve housing with an inlet and an outlet as well as a mixing chamber and a nozzle. The valve further includes a lateral opening for enabling an introduction of air to be mixed with the irrigation liquid and for draining of irrigation liquid. A number of the valves may be used in an irrigation plant with one valve being provided under each cultivation table and being activated by a magnetic valve disposed in an inlet pipe for providing water under pressure.
