Hunter Node Irrigation Control

What is a Hunter Node

The Hunter Node was first introduced by Hunter Industries in 2012.  The Hunter Node is a 9 volt battery power control unit that can be used to operate any size Hunter Valves using a 9 volt dc latching solenoid The Hunter Node is available as 2 options.  A Hunter Node 100 which comes with the Hunter solenoid valve and the Hunter 400 which can control up to 4 valves however the valves have to be purchased as a separate item.

When Would you Use A Hunter Node

In most situations we would suggest that you use the industry standard 24 volt ac valves with a mains powered control unit.  These are by far the cheapest and most reliable method of controlling your irrigation system.  However there are occasions when this is not possible.  As an example a remote location on a gold course or garden or sometimes the inconvenience that is associated with installing a low voltage lead to a valve box after landscaping has been complete.  In these situations the Hunter Node is ideal.  The valve is installed in to the line that needs to be controlled and after a few key clicks it is ready to run.

What Is The Difference Between The Hunter Node 100 and 400

The Hunter Node 100 comes complete with the solenoid valve.  This is pre wired and pre fitted ready to thread in to any Hunter Solenoid valve.

The valve once installed is compact and very easy to operate

The Hunter Node 400 is used to control any number of valves up to 4.  The 400 is just the control unit and to this you would need to add the valves with the dc solenoids.  The example below is operating three of the Hunter 1″ BSP valves

In Order for the above to operate you would have to purchase in addtion to the control unit

Three Dc Latching Solenoids and three valve bodies

What Is The Difference Between A Pressure Releif Valve And a Pressure Regulator

A pressure releif valve is a valve that will open when the pressure exceeds a certain level and once open will allow water to bypass the system and return the water to the tank. These are installed in very high pressure systems and will protect the pipe and equipment etc.  They will protect pumps as they will make sure that water continues to move through the pump even if a fault occurs that prevents water from running ie a valve fails to open and the pump would eventually start boiling the water in the pump causing permanent damage


A pressure regulator will regulate the pressure on the outlet of the regulator and make sure that the pressure does not exceed the pre set amount. So the regulator will make sure that any equipment connected to the outlet of teh regulator is protected however pressure will be build up on the inlet
