Abstract: A multifunction valve includes a valve body defining an inlet, and outlet and an interior chamber. A flow control gate is disposed within the interior chamber and is rotatable through an arcuate range of positions relative to the outlet providing a high level of precision control of a fluid flow rate through the multifunction valve. A method of modulating a fluid flow rate includes directing fluid flow through a multifunction valve from an inlet to an outlet, the multifunction valve including a flow control gate, adjusting the flow rate through the multifunction valve by rotating a control shaft to position the flow control gate to variably occlude the outlet of the fluid control valve.

Abstract: Techniques for controlling a solid fuel combustion appliance, e.g., a wood burning stove, are disclosed. A control system measures an exhaust gas temperature of airflow through an outlet of the solid fuel combustion appliance. The control system determines a derivative of the exhaust gas temperature with respect to time. The derivative of the exhaust gas temperature with respect to time is compared to a predetermined threshold. The control system modulates the inlet damper in response to determining that the derivative of the exhaust gas temperature with respect to time reaches the predetermined threshold.

Abstract: A valve assembly includes a valve body defining a fluid inlet in fluid communication with a fluid outlet. The valve body has an inner body surface defining an interior chamber extending between the fluid inlet and the fluid outlet. A valve element is disposed within the interior chamber and rotatable through a range of positions relative to the outlet providing a high level of precision control of a fluid flow rate through the valve assembly. A valve seat with a seal is positioned around a valve element. The valve seat is configured to self-adjust its inner radial diameter to correspond to the outer radial diameter of the valve element to maintain a portion of an inner seat surface in contact with an outer valve surface of the valve element through the range of positions.

Abstract: A system and controller where the pressure of the air is continuously monitored or read at a designated exhaust point and adjustments made to the flow of the air and gas to keep the efficiency of the appliance at a maximum to control the appliance (or the burner for an appliance) within specifications as dictated by the customer or consumer rather than training the user.

Abstract: A multifunction valve includes a valve body defining an inlet, and outlet and an interior chamber. A flow control gate may be disposed within the interior chamber and comprises one or more protrusions configured to provide a high level of precision control of a fluid flow rate through the multifunction valve as the flow control gate is rotated through an arcuate range of positions. The protrusions may comprise a cut-out portion, wherein the size and/or shape of the cut-out may be configured to modify the fluid flow rate through the multifunction valve. A method of modulating a fluid flow rate includes directing fluid flow through a multifunction valve from an inlet to an outlet, the multifunction valve including a flow control gate, adjusting the flow rate through the multifunction valve by rotating a control shaft to position the flow control gate to variably occlude the outlet of the multifunction valve.
