The present invention relates to a piezoelectric gas control valve for hot water in a boiler, and, more specifically, to the piezoelectric gas control valve controlling the amount of gas combusted inside the boiler, adjusting the pressure of the gas, preventing the leakage of the gas, and securing safety by installing an on/off valve, a flow rate control valve, and a pressure reducing valve in a single valve block thereof, wherein the on/off valve opens a flow path when the boiler is operated, and blocks the flow path with a leakage preventing function when the boiler is turned off, the pressure reducing valve controls the pressure of the gas inside the boiler according to whether or not hot water is used, and the flow rate control valve proportionally controls the flow rate of the gas according to the demand of a user, thereby simplifying the configuration of the piezoelectric gas control valve and easily installing the piezoelectric gas control valve.
