How an Indexing Valve works? Indexing valves are activated by sufficient water pressure being turned on and off. Therefore, no electrical wiring is required to the solenoid valve. All that is needed for an indexing valve to operate is a controller to turn on and off the water supply (pump or solenoid).
What is an indexing valve?
Indexing valves allow an irrigation system to change zones. Easy to install and maintain, K-Rain's patented hydraulic actuated indexing valve changes zones when the water flow is interrupted. These valves are ideal on pump applications, on site waste water disposal and reclaimed water systems.
What is indexing and how does it work?
How does Indexing Work? In reality the database table does not reorder itself every time the query conditions change in order to optimize the query performance: that would be unrealistic. In actuality, what happens is the index causes the database to create a data structure.
What is a K-rain indexing valve?
Easy to install and maintain, K-Rain's patented hydraulic actuated indexing valve changes zones when the water flow is interrupted. These valves are ideal on pump applications, on site waste water disposal and reclaimed water systems. Our 4000 and 6000 series replace the old Hydrotek models.
What happens when an index is added to a database?
In actuality, what happens is the index causes the database to create a data structure. The data structure type is very likely a B-Tree. While the advantages of the B-Tree are numerous, the main advantage for our purposes is that it is sortable.
How does a Fimco indexing valve work?
FIMCO Hydro Indexing Valves are preassembled with a sequencing cam depending on how many zones are on a particular sprinkler system. The cam can be easily removed and replaced by a different cam if sections are added or eliminated. The Hydro Indexing Valve must be cammed for the proper number of zones!
Why is my sprinkler not changing zones?
If your sprinkler system isn't working in all zones, chances are the problem is localized to the one or two zones that aren't working. Each zone has its own valve, so that's a good place to look. Head out to each valve and see if it is opened fully, broken, rusted, or stuck. Turn valves to the left to open them more.
How do you install an index valve?
The Index Headset has three plugs:Plug the headset DisplayPort cord into your graphics card port (if you have a laptop you may need an adapter.Plug the headset USB cord into a USB 3.0 port on your computer.Using the headset power adapter, plug your headset into a power outlet.
How do you change a Fimco indexing valve?
Replacing the Fimco Valve Top Loosen the coupling from the coupling nut Unscrew the 6 or 8 screws (depending on the valve size) from the perimeter of the valve top Lift the valve top with the stem and disc assembly attached from the valve bottom making sure not to lose your screws.
Why does one of my sprinkler zones have no pressure?
Often when your sprinkler system was running fine, and then one zone began to lose water pressure, the culprit is a leak in the zone's lines or a leak at a nozzle or two. Leaking nozzles won't produce the same water pressure and need to be replaced, which is fairly simple.
Why is only one zone working on my sprinkler system?
If only one zone isn't working, the field wire is damaged. If none of the zones in a control valve box is working, the common wire is damaged, although the field wires could also be bad.
How much space do you need for valve index?
6.5ft x 5ftThis is all very painless as long as you have the recommended amount of room (2m x 1.5m/6.5ft x 5ft) and can put your PC and VR headset near your Base Stations. However, the Valve Index also supports seated and standing play, and adapts to smaller playspaces with ease.

How Does the Database Know What Other Fields in the Table to Return?
Database indexes will also store pointers which are simply reference information for the location of the additional information in memory. Basically the index holds the company_id and that particular row’s home address on the memory disk. The index will actually look like this:
