Non Rising Stem Gate Valves Irrigation Network

One of mankind’s oldest technical applications are the irrigation of fields for agriculture. This allowed the first advanced civilisations to flourish along the Nile, Euphrates and Tigris and is still today a decisive factor in feeding the growing world population.

Of great importance here is that the valuable commodity water is used economically, but also that sufficient irrigation takes place for plant growth. Equally important is the transportation of the water to the irrigation site with as little loss and as a cost-effectively as possible.

The functional range of TALIS valves therefore extends from obtaining the water from surface waterways, the ground water or specially installed water storage facilities to distributing the water to the spray-irrigation systems.
