Application
The FlowCal™ pressure independent balancing valve maintaines
a fixed flow rate within varying system differential pressure ranges.
The design incorporates an exclusive flow cartridge, made of an
anti-scale, low noise polymer and a compact DZR low-lead brass
valve body for use in hydronic and domestic water systems. The
FlowCal™ eliminates the need for onsite measurements and trial and
error flow rate setting as required with manual calibration valves. It is
ideal for applications including open fan coil systems and hot water
recirculation balancing.

Dimensions
Typical Specification
Furnish and install on the plans and described herein, a Caleffi FlowCal™
compact automatic flow balancing valve as manufactured by Caleffi. Each
balancing valve must be designed with an inline body style with 1/2", 3/4", or
1" union sweat, NPT male threaded, press or PEX crimp end connections.
The design must include a DZR low-lead brass body and connections
(<0.25% Lead content) certified by ICC-ES, high abrasion resistant, anti-
scale, low noise, interchangeable polymer flow cartridge, stainless steel
spring, and peroxide-cured EPDM seals. Each valve must be designed for
fixed flow rates ranging from 0.35 to 10 gpm with ±10% accuracy, 232 psi
(16 bar) maximum working pressure and working temperature range of 32
to 212˚F (0 to 100˚C). Each balancing valve shall be a Caleffi model 127 or
approved equal.
