<strong>LK</strong> 826 ThermoBac is a 3- way check valve with low opening<br />
pressure and high fluid capacity. The valve is especially<br />
suitable for heating systems with storage tanks. The check<br />
valve prevents self-circulation from storage tank to boiler<br />
after the fire has gone out. In case of power failure or pump<br />
breakdown <strong>LK</strong> 826 ThermoBac automatically opens for selfcirculation.<br />
The valve should be mounted so that the flap in the check<br />
valve closes by its own weight.<br />
