Typical Specifi cation
Furnish and install on the plans and describing herein, a Caleffi FLOWCAL™
automatic fl ow balancing valve and integral ball valve as manufactured by
Caleffi . Brass body. Each balancing valve must be designed with a Y-style
brass body NPT female or sweat with union by NPT female or sweat end
connections, with brass pressure and temperature test port plugs. The
balancing valve design must include an anti-scale polymer fl ow cartridge,
stainless steel spring and EPDM seals. The integral ball valve must include
a chrome-plated brass ball, PTFE ball seat and stem seal, and a zinc-
plated steel lever with vinyl grip. Each valve must be designed for fi xed fl ow
rates ranging from 1/2 - 21 gpm with ±10% accuracy, 400 psi (400 WOG)
maximum working pressure and working temperature range of 32 - 212°F
(0 -100°C).
(See product instructions for specifi c installation information.)

Application
The FlowCal™ automatic fl ow balancing valve maintains a constant fi xed
fl ow rate within varying system differential pressure ranges. Operation is
fully automatic requiring no manual adjustment. The 121 series utilize an
exclusive, interchangeable fl ow cartridge, made of anti-scale, low noise
polymer for use in cooling and heating systems. The FlowCal 121 series
automatic fl ow balancing valves are available with integral shut-off ball valve
and optional factory-installed pressure and temperature test ports.
Drain valves are also available as an accessory for installing in the blowdown
port connection.
