Protection Against Boiler Corrosion and Fouling

ATSVB Valves for return temperature control, with automatic by-pass balancing

ATSVB load valves mix cool return water from a heating system or thermal store with hot water from a boiler flow, keeping boiler return water (i.e. its heat transfer surfaces) at a temperature that will not allow condensation to occur. The boiler then works with higher effciency and it’s service life is extended.

The valves feature automatic by-pass balancing. The exact control prevents boiler overheating and keeps a steady flow rate through a boiler under any temperature if the system is properly designed. When restricting the flow through one port, it opens the other one simultaneously.
