Types of Nodes

Pumps: is a device that moves fluids by mechanical action. This is also the source node of the mainline.


 Valves: allow water to exit the system. In the mainline, valves are used to manage the flow to blocks and pivots.

The irrigation blocks will each have a valve that acts as source node. The block valve is also the connection between the inlet to the block and the mainline.

Emitters: can either be sprinklers in a solid set block or drippers in a dripline block. It is used to transfer water from a pipe or tube to the area that is to be irrigated. Typical emitter flow rates are from 0.16 to 4.0 U.S. gallons per hour (0.6 to 16 L/h). In many emitters, flow will vary with pressure, while some emitters are pressure compensating.

Fittings: a device that makes a connection between pipes.

Regulators: a device that maintains a designated characteristic, for example when the pressure in the system needs to be reduced to a certain value.

Boosters: a device that increases the water pressure of water that is already moving.

Nodes are defined in the nodes database.
