Being able to identify a product is critical to its repair or replacement. With the shift toward online sales, it’s also important for both the manufacturer and the consumer to ensure the correct product is ordered. The purpose of this guide is to help you make an informed decision. Let’s get started.
The first step in identifying a FIMCO valve is to check whether it has six or eight screws around the perimeter.
- Six screws = mini (small) valve
- Eight screws = standard (large) valve
The Mini Valve
The mini valve has six screws around the perimeter. It comes in two pipe size configurations, 1″ in x 1″ out and 1.25″ in x 1.25″ out, with five outlet configurations.
The 1000 Series
The mini valve has six screws around the perimeter. It comes in two pipe size configurations:
- 1″ in x 1″ out
- 1.25″ in x 1.25″ out
Each size offers several outlet configurations.


Take note of how the outlets are barely seeing (yellow circle) around the screws.
The 2000 Series (1.25″ Mini)
The 2000 series valves have a 1.25″ inlet and either four or six 1.25″ outlets. Like the 1000 series, the 2000 series have six screws aroung the perimeter of the valve and are considered our “mini” valves.
The four-outlet model can run 2, 3, or 4 zones and is pictured below. The six-outlet model can run 2-6 outlets, though in order to run 3 or 4 a special white cam is needed.
Take note of the yellow circle in the picture below. Notice how the 1.25″ outlets stick out a lot further on the 2000 series.


The six-outlet models are going to look very similar, the 1.25″ outlets stick out further from the valve top. You can see pictures of them on their pages here: The 1000 series with 6 outlets.
And here: The 2000 series with 6 outlets.
The 8-outlet model is a 1000 series as it is only available in 1″.
The Standard Valve
The standard valve has eight screws around the perimeter. It comes in two pipe size configurations, 1.5″ in x 1.25″ out, and 1.5″ in x 1.5″ out, with four outlet configurations.
The 3000 Series (1.25″ Standard)
The 3000 series valves have a 1.5″ inlet and either four or six 1.25″ outlets. The easiest way to identify these valves is firstly by their eight screws around the perimeter, and secondly the outlets pipes are slightly smaller than the inlet pipe.
The four-outlet model can run 2, 3, or 4 zones, you can find pictures of it here: 3000 series with four outlets.
The six-outlet model can run 2-6 outlets, though in order to run 3 or 4 a special white cam is needed. You can find it here: 3000 series with 6 outlets.
The 4000 Series (1.5″ Standard)
The 4000 series valves have a 1.5″ inlet and either four or six 1.5″ outlets. The easiest way to identify these valves is firstly by their eight screws around the perimeter, and secondly the outlets pipes are the same size as the inlet pipe.
The four-outlet model can run 2, 3, or 4 zones and you can find pictures of it here: 4000 series with four outlets.
The six-outlet model can run 2-6 outlets, though in order to run 3 or 4 a special white cam is needed. You can find it here: 4000 series with 6 outlets.
