Typical Specification
Furnish and install on the plans and describing herein, a Caleffi recirculation
thermal balancing valve, as manufactured by Caleffi. Each balancing valve
must be designed with a DZR low-lead brass body certified to NSF/ANSI
372 by ICC-ES, file PMG-1360. Certified to NSF/ANSI 61 (180°F/82°C
Commercial Hot) by ICC-ES, file PMG-1512. PSU adjustable cartridge,
peroxide-cured EPDM seals, ABS adjustment knob. The balancing valve
must include ½” or ¾" NPT female connections. Each valve has 230
psi (16 bar) maximum working pressure and 105–150°F (40 – 65°C)
adjustable temperature range. Provide with optional outlet temperature
gauge with 30-180°F (0–80°C) temperature scale, optional check valve. and
optional pre-formed insulation shell. Each valve shall be Caleffi model 1164 or
approved equal. (See product instructions for specific installation information.)
CALEFFI
Application
The ThermoSetter™ 1164 series adjustable thermal balancing valve
is used for automatic balancing of recirculation loops in domestic
hot water systems, to speed hot water delivery, reduce water waste
and save energy. The internal thermostatic balancing cartridge
automatically modulates flow to ensure a constant temperature in the
recirculation piping system. The 116 Series has an adjustment knob
with 105°F to 150°F (40°C to 65°C) temperature scale indication. The
adjustment knob is lockable for tamper-proofing. An integral dry-well
holds a slide-in temperature gauge for local indication, or a sensor
for remote temperature sensing. The optional check valve protects
against circuit thermo-syphoning. The valve is ICC-ES certified to
NSF/ANSI 61 (180°F/82°C Commercial Hot), and NSF/ANSI 372,
low lead laws. It meets codes IPC, IRC, UPC and NPC for use in
accordance with the US and Canadian plumbing codes.
