Abstract: A stepper-motor gas valve control is disclosed that includes a main diaphragm in a chamber that controllably displaces a valve relative to an opening in response to changes in pressure, to adjust fuel flow through the valve. A servo-regulator diaphragm is provided to regulate flow to the main diaphragm, to thereby control the rate of fuel flow. A stepper motor is configured to move in a stepwise manner to displace the servo-regulator diaphragm, to control fluid flow to the main diaphragm. A controller mounted on the stepper-motor regulated gas valve control receives and converts an input control signal from a heating system to a reference value between 0 and 5 volts, and selects a corresponding motor step value. The control responsively moves the stepper-motor in a step wise manner to displace the servo-regulator diaphragm and thereby regulates the rate of fuel flow through the valve.

Abstract: A modulating gas valve assembly includes a modulating gas valve to variably control a flow of gas through the gas valve assembly and a control circuit. The control circuit includes a valve memory storing a calibration table for the modulating gas valve, and a controller communicatively coupled to the peripheral component. The calibration table includes a plurality of control settings for the modulating gas valve, each control setting being associated with a different gas flow rate. The controller is programmed to receive a command to open the gas valve, and to control the gas valve to a target control setting in the calibration table adjusted in accordance with a valve offset.

Abstract: A valve apparatus includes substantially co-aligned first and second valve seats and substantially co-aligned first and second valve members. The first valve member is moveable relative to the first valve seat between at least an open position in which the first valve member is spaced from the first valve seat and a closed position in which the first valve member is seated against the first valve seat. The second valve member is moveable relative to the second valve seat between at least an open position in which the second valve member is spaced from the second valve seat and a closed position in which the second valve member is seated against the second valve seat. An armature is operable for moving the first and second valve members, in response to a magnetic field generated by a coil.
