Electronic controllers switch water flow using durable valves.

Valves connect to pipes, and are usually underground. You want them to be very reliable, and free from problems for years.

The valves fitting smaller pipes are typically used in residential systems, or for small areas which are special zones in a larger system. The  Nelson 7900 series valves incorporate heavy-duty corrosion resistant materials for sturdy and dependable years of service. They have a glass reinforced nylon body bonnet to prevent leaks and breaks, and a stainless-steel plunger and spring to prevent seepage and corrosion. A simple valve design that's easy to use.

We particularly like the Nelson valves - simple, robust and dependable.  Nelson valves were illustrated above, but HunterBermad, Dorot and other manufacturers are also available.
