2. Irrigation sprinkler - Wikipedia

   en.wikipedia.org/wiki/Irrigation_sprinkler

   Sprinkler irrigation is the method of applying water in a controlled manner in way similar to rainfall. The water is distributed through a network that may consist of pumps, valves, pipes, and sprinklers. [ 1 ] Irrigation sprinklers can be used for residential, industrial, and agricultural usage. It is useful on uneven land where sufficient ...

3. Irrigation - Wikipedia

   Most automatic systems employ electric solenoid valves. Each zone has one or more of these valves that are wired to the controller. When the controller sends power to the valve, the valve opens, allowing water to flow to the sprinklers in that zone. There are two main types of sprinklers used in lawn irrigation, pop-up spray heads and rotors.

4. Solenoid valve - Wikipedia

   en.wikipedia.org/wiki/Solenoid_valve

   A solenoid valve is an electromechanically operated valve. Solenoid valves differ in the characteristics of the electric current they use, the strength of the magnetic field they generate, the mechanism they use to regulate the fluid, and the type and characteristics of fluid they control. The mechanism varies from linear action, plunger-type ...

5. Rain Bird - Wikipedia

   en.wikipedia.org/wiki/Rain_Bird

   The Rain Bird horizontal action impact-drive sprinkler head was recognized as a historic landmark of agricultural engineering in 1990 by the American Society of Agricultural and Biological Engineers. [4] This invention led to sprinkler irrigation development that currently exceeds 50,000,000 acres (78,000 sq mi; 200,000 km 2) worldwide.

6. Solenoid (engineering) - Wikipedia

   en.wikipedia.org/wiki/Solenoid_(engineering)

   In engineering, a solenoid is a device that converts electrical energy to mechanical energy, using an electromagnet formed from a coil of wire. The device creates a magnetic field [1] from electric current, and uses the magnetic field to create linear motion. [2][3][4] In electromagnetic technology, a solenoid is an actuator assembly with a ...

7. Zone valve - Wikipedia

   en.wikipedia.org/wiki/Zone_valve

   Zone valve. A zone valve is a specific type of valve used to control the flow of water or steam in a hydronic heating or cooling system. In the interest of improving efficiency and occupant comfort, such systems are commonly divided up into multiple zones. [1] For example, in a house, the main floor may be served by one heating zone while the ...
