Thermostatic Balancing Valve (Thermal Recirculation Valve)

Mô tả sản phẩm

The INTA Series 600 Thermostatic Balancing Valve is a specialized temperature balancing valve designed for domestic hot water (DHW) recirculation systems. Installed on the return branch of each hot water circuit, it automatically regulates return water temperature to ensure balanced hot water distribution throughout the entire building.

Using an adjustable thermostatic cartridge, the valve continuously modulates flow according to the return water temperature, eliminating temperature imbalance between different branches. This ensures faster hot water delivery, minimizes water waste, and improves occupant comfort while reducing energy consumption.

A key feature of the Series 600 is its automatic thermal disinfection (Legionella control) capability. During high-temperature disinfection cycles, the valve automatically opens to allow sufficient hot water circulation throughout the system, helping eliminate Legionella bacteria and supporting safer domestic hot water operation.

Manufactured from low-lead DZR brass, the valve incorporates an integrated temperature gauge and offers an optional check valve, making it an ideal solution for hotels, hospitals, healthcare facilities, residential developments, resorts, and other buildings requiring reliable domestic hot water recirculation.

Main Features

The INTA Series 600 automatically balances domestic hot water temperature while supporting thermal disinfection against Legionella. Its thermostatic control, integrated temperature gauge, and durable DZR brass construction improve hot water availability, enhance hygiene, reduce energy consumption, and simplify system maintenance.
