How does a smart valve work?The valve has a circuit board that can control a pilot valve, it energizes an HSI, it has flame rectification, it energizes the main valve, it does it’s own diagnostics, and can be used to energize another 24 or 120v circuit. And some models don’t even use a pilot burner to light the main burners.
