The Caleffi 132556A is a QuickSetter manual balancing valve with a built-in direct-reading flow meter, 3/4" integral press connections, and a 2.0-7.0 GPM working range. It sets and verifies circuit flow rate in hydronic heating and chilled water systems without separate pressure gauges, charts, or differential pressure meters, and ships with a pre-formed closed cell PE-X insulation shell for heat loss and condensation control.
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
- Setting design flow in hydronic heating and chilled water circuits
- Balancing secondary loops, terminal units, and zone branches
- Glycol-based systems up to 50% glycol concentration
- Insulated piping runs where the included shell controls heat loss and condensation
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 circuit 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.
Included Insulation Shell
A pre-formed closed cell PE-X shell ships with the valve, minimizing heat loss in heating service and preventing condensation in chilled water service.
Quarter-Turn Shutoff
The 90 degree ball control stem doubles as a service shutoff once the balance position is memorized on the indicator.
Wide Size Coverage
Part of a 1/2 to 2 inch threaded and press family with flanged models to 4 inches, keeping balancing hardware consistent across the project.

Frequently Asked Questions
What flow range does the Caleffi 132556A cover?
The 132556A covers 2.0-7.0 GPM with a direct-reading graduated scale and ±10% accuracy. Other sizes in the QuickSetter 132 family cover 0.5 to 50 GPM in threaded and press connections.
Is the Caleffi 132556A low lead certified for potable water?
No. The 132556A is a standard brass valve intended for closed hydronic heating and chilled water systems. For potable domestic hot water recirculation, use the DZR low-lead QuickSetter+ 132AFC series, which is certified to NSF/ANSI/CAN 372.
Does the Caleffi 132556A come with insulation?
Yes. A pre-formed closed cell PE-X insulation shell is included to minimize heat loss and prevent condensation in chilled water service.
Does the Caleffi 132556A include a temperature gauge?
No. The QuickSetter 132 series does not offer a temperature gauge option; the QuickSetter+ 132AFC series offers dual-scale outlet gauge models.
What is the warranty on the Caleffi 132556A?
Caleffi covers this product under its standard two-year limited warranty against defects in material and workmanship. ZOT Supply is an authorized Caleffi distributor.
