The Caleffi 132100A is a QuickSetter flanged manual balancing valve with a built-in direct-reading flow meter, 4" ANSI B16.1 125 Class RF flanged connections, and a 55 - 210 GPM working range. The cast iron body and handwheel-operated control make it suited to large hydronic distribution mains, risers, and central plant circuits where flow must be set and verified without separate pressure gauges, charts, or differential pressure meters.
To balance a circuit, pull the flow meter operating ring, read the GPM value directly on the graduated scale, adjust the valve to the design flow rate, and release. The bypass closes automatically after the reading, isolating the flow meter during normal operation for reliable readings over time.
Best For
- Balancing distribution mains and risers in commercial hydronic systems
- Chilled water and heating plant circuits from 30 to 210 GPM
- Glycol-based systems up to 50% glycol concentration
- Retrofits standardizing on direct-reading balancing hardware
Key Features
Pull-Adjust-Release Flow Setting
The built-in flow meter reads GPM directly on a graduated scale while you adjust the valve, so one technician can balance the main in a single step.
Automatically Isolated Flow Meter
The bypass opens only while the operating ring is pulled and closes automatically when released, isolating the flow meter during normal operation.
Handwheel Operation
A 5-1/2" diameter handwheel gives controlled adjustment of the large-bore ball at line pressures.
ANSI Flanged Connections
ANSI B16.1 125 Class RF flanges bolt directly into commercial piping without transition fittings.
Family Consistency
Shares the QuickSetter reading method with the 1/2 to 2 inch threaded and press models, keeping balancing procedures identical across the project.

Frequently Asked Questions
What flow range does the Caleffi 132100A cover?
The 132100A covers 55 - 210 GPM with a direct-reading graduated scale and ±10% accuracy. The flanged family spans 30 to 210 GPM across 2-1/2, 3, and 4 inch sizes.
What flange standard does the Caleffi 132100A use?
ANSI B16.1 125 Class RF flanges in 4 inch nominal size, mating directly to standard commercial hydronic piping.
Is the Caleffi 132100A low lead certified for potable water?
No. The flanged QuickSetter has a cast iron body and is intended for closed hydronic heating and chilled water systems, not potable water.
How is the Caleffi 132100A adjusted?
A 5-1/2" handwheel rotates the ball while the built-in flow meter displays GPM, so the valve is set to design flow in one operation.
What is the warranty on the Caleffi 132100A?
Caleffi covers this product under its standard two-year limited warranty against defects in material and workmanship. ZOT Supply is an authorized Caleffi distributor.
