Thermal Balancing Valve

Thermal Balancing Valve

The themmostatic regulator for domestic hot water re-circulation systems automatically maintains the specified water temperature.

Detail Description

The themmostatic regulator for domestic hot water re-circulation systems automatically maintains the specified water temperature.
Function
The thermostatic regulator is intended to be installed in the return pipe of each re-circulation circuit, automatically maintaining the specified water temperature.
The regulator controls the flow rate in accordance with the inlet water temperature by means of a dedicated intemal themmostatic cartridge.
When the water temperature approaches the set value, the obturator progressively close and reduces the flow passage reducing the amount of water re-circulating.
The water supplied by the re-circulation pump is available to be distributed to other branches in the system, resulting in effective automatic thermal balancing.
Temperature gauge available.
Insulation shell available upon request
