Thermal balancing valve from Caleffi
Caleffi’s 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 pumping energy. The internal thermostatic balancing cartridge automatically modulates flow to ensure a constant temperature in the recirculation piping system. It is adjustable from 95° to 140° F with a locking adjustment knob. An integral dry well holds a slide-in temperature gauge for local indication or a sensor for remote temperature sensing. An optional check valve protects against circuit thermo-syphoning. For applications that require thermal disinfection and protection against Legionella, a self-contained or remote control bypass cartridge is available.
