Caleffi FlowCal™ Balancing Line Expands With Added Features

Share With:

An industry leader in hydronic and plumbing balancing technology, Caleffi North America has expanded their product offering with a Y-pattern dynamic balancing valve. The new 128 FlowCal™ Series valves with DZR low-lead brass bodies are now in stock and available for order in North America. This valve series was developed to make flushing, commissioning, cleaning and balancing easy with a cartridge that can be temporarily removed while the circuit is flushed. Factory-installed pressure temperature ports allow for quick flow verification, all in a compact design.

The 128 is functionally similar to the popular 127 Series, but with an easy access port for servicing or changing the flow control cartridge without removing the valve body from the piping. The 128 uses the same flow cartridges as the 127 Series (0.35 GPM to 10 GPM flow control), has dual union connections, has the same pipe sizes and tailpiece connection types (sweat, NPT, press, PEX expansion and PEX crimp).

Used in plumbing applications, the FlowCal+ models have an inlet check valve to prevent reverse flow and an optional outlet temperature gauge for local indication. The easy to swap, dynamic flow cartridges maintain a specified flow rate, with no adjustments or differential pressure charts required to set up. Patented anti-scale low noise polymer cartridges are utilized for silent operation.
