    摘要： The gas valve unit (100) includes a valve member (122) moveable relative to a valve seat (102). An input signal to a coil (120)controls the extent of movement of the valve member (122) relative to the valve seat (102) to control a gas flow rate through the gas valve unit (100). A setting adjustment device provides a setting adjustment input for calibrating at least one desired gas flow rate. A valve controller (20) is in communication with the setting adjustment device and the coil (120). The valve controller (20) is configured to receive an activation signal and to responsively send an input signal to the coil (120) to move the valve member (122) to establish at least one desired gas flow rate corresponding to the activation signal. The valve controller (20) is configured to adjust the input signal to the coil (120) based on the setting adjustment input, to thereby enable field adjustment of the level of the at least one desired gas flow rate.
