FlowCal™ Union Y-body Automatic Flow Balancing Valve - NA Market

FlowCal 128AF series, y-body automatic balancing valve, with polymer cartridge, includes PT ports, is pressure independent and maintains a fixed flow rate as differential pressures vary. It has an anti-scale, low noise polymer flow cartridge. Constructed of DZR low-lead brass, FlowCal 128AF series is suited for use in plumbing applications such as hot water recirculation systems, and can also be used in hydronic systems.

The FlowCal 128AF series Y-pattern design uses the same flow cartridges as the Caleffi FlowCal 127AF series. Because it can remain in the piping, the y-body simplifies serviceability with an easy-to-remove flow cartridge for flushing and inline change out. It also includes factory-installed PT ports to verify and certify flow rates.

The FlowCal 128AF series balancing valves are available with NPT male, sweat, press, PEX crimp and PEX expansion union connections. The union nut makes installation and maintenance fast,easy and efficient for a variety of tailpiece options.
