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, and stainless steel & copper
adjustable cartridge; 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 95-140°F (35–60°C) adjustable
temperature range. Equipped with 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 1161 or approved
equal. (See product instructions for specific installation information.)
CALEFFI
Application
The THERMOSETTER™ 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 95°F to
140°F (35°C to 60°C) temperature scale indication. 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 1162xx Series is available with a “disinfection” by-pass cartridge,
for use in systems which are designed to perform thermal disinfection
for prevention of Legionella. When the disinfection cartridge
senses 160°F (70°C) water, indicating disinfection control mode, it
automatically opens a by-pass flow path to allow sufficient flow for
disinfection to occur. When the temperature drops back to normal
range, the disinfection by-pass cartridge closes to return flow control
to the balancing cartridge.
The 1163xx Series is also available with a "disinfection" valve that
is controlled by a 24V spring return thermo-electric actuator, rather
than thermostatically, thus allowing thermal disinfection mode to be
controlled remotely by an automation system.
