Indexing Valve Series
Identification of an indexing valve is fairly straightforward. If you know the pipe size in and out you can simply consult the following list:
- 1000 Series – 1″ in and 1″ out
- 2000 Series – 1.25″ in and 1.25″ out
- 3000 Series – 1.5″ in and 1.25″ out
- 4000 Series – 1.5″ and 1.5″ out
These model numbers change when you visit the bigger retail distributors. If you’re shopping at Lowe’s or The Home Depot, consult the following list:
- 9254 – 1″ in and 1″ out with four outlets
- 9256 – 1″ in and 1″ out with six outlets
- 9258 – 1″ in and 1″ out with eight outlets
- 9264 – 1.25″ in and 1.25″ out with four outlets
- 9266 – 1.25″ in and 1.25″ out with six outlets
- 92684 – 1.5″ in and 1.25″ out with four outlets
- 92686 – 1.5″ in and 1.25″ out with six outlets
- 92694 – 1.5″ in and 1.5″ out with four outlets
- 92696 – 1.5″ in and 1.5″ out with six outlets
Counting the Screws
In the most basic sense, the FIMCO Hydro-Indexing Valve comes in two different sizes and they are standard and mini. You can tell which is which simply by counting the screws around the perimeter. This is especially helpful when all that’s needed is a replacement valve top.
If there are six screws around the perimeter, then it’s a mini valve. This would mean it’s either 1″ in and 1″ out or 1.25″ in and 1.25″ out.
If there are eight screws around the perimeter, then it’s a standard valve. This means it’s either 1.5″ in and 1.25″ out or 1.5″ in and 1.5″ out.
Remember:
- six screws = mini (or small) valve top
- eight screws = standard (or large) valve top
How About Pictures?
Sometimes the easiest way is to simply look at the valve. Keep in mind that the valve was green (or charcoal gray) in color for many years. All valves are now black. That being said, let’s see if you can pick yours out from this lineup located here:
