Description

LK 826 ThermoBac is a 3- way check valve with low opening pressure and high fluid capacity. The valve is especially suitable for heating systems with storage tanks. The check valve prevents self-circulation from storage tank to boiler after the fire has gone out. In case of power failure or pump breakdown LK 826 ThermoBac automatically opens for self-circulation.

The valve should be mounted so that the flap in the check valve closes by its own weight.
