This is a gas flow control valve that regulates the supply of gas to an individual surface burner on a cooktop. It connects to the burner control knob and adjusts the flame from high to low. Replace this valve if a burner won't ignite, the flame is uneven or won't adjust properly, or if you detect a gas leak around the valve area.

If your gas cooktop burner won't ignite, won't adjust flame, or has uneven heat, you may need a new valve. This part controls gas flow to the burners.
