The present disclosure relates to a heating, ventilation, and air conditioning (HVAC) system that includes a heat exchanger configured to circulate a working fluid therethrough, a valve configured to regulate a flow rate of the working fluid through the heat exchanger, and a valve controller configured to modify a valve position control signal received from an external controller, separate from the valve controller, based on a temperature differential of the working fluid entering and exiting the heat exchanger.

Temperature control valve

An integrated device in an HVAC system is configured to modify an environmental condition of a building. The integrated device includes a valve configured to regulate a flow of a fluid through a conduit and an actuator. The actuator includes a motor and a drive device. The drive device is driven by the motor and coupled to the valve for driving the valve between multiple positions. The integrated device further includes a processing circuit coupled to the motor. The processing circuit is configured to detect device identifying information for the valve or the actuator and to detect the integrated device location within the building.

Integrated smart actuator and valve device applications

A system configured to modify an environmental condition of a building includes a valve configured to regulate a flow of a fluid and an actuator. The actuator includes a motor and a drive coupling, the drive coupling driven by the motor and coupled to the valve for driving the valve between multiple positions. The system further includes a flow rate sensor configured to measure the flow rate of the fluid through the valve and a processing circuit coupled to the motor and the flow rate sensor. The processing circuit is configured to receive a flow rate setpoint and a flow rate measurement, determine an actuator position setpoint based on the flow rate setpoint and the flow rate measurement, and operate the motor to drive the drive coupling to the actuator position setpoint. The flow rate sensor and the processing circuit are located within a common integrated device chassis.

Integrated smart actuator and valve device

A building management system is configured to modify an environmental condition of a building. The building management system includes a valve assembly, an actuator device, and a network sensor device. The actuator device includes a motor, a drive device driven by the motor and coupled to the valve assembly, and a controller coupled to the motor. The controller includes a microprocessor and a control application configured to enable closed loop control of the valve assembly. The network sensor device is communicably coupled to the actuator device and configured to measure an environmental property. The control application is configured to perform the closed loop control of the valve assembly based on an input control signal from a mobile device and the measured environmental property from the network sensor device.

Actuator

A cascaded control system configured to modify an environmental condition of a building includes a valve configured to regulate a flow of a fluid through a conduit, an actuator including a motor and a drive device, and a communications mechanism. The communications mechanism is configured to receive a flow rate setpoint from an external control device of an outer control loop. The cascaded control system further includes a processing circuit coupled to the motor and the communications mechanism. The processing circuit is configured to determine an actuator position setpoint using a cascaded feedback control mechanism based on the flow rate setpoint and a flow rate measurement from a flow rate sensor of an inner control loop and to operate the motor to drive the drive device to the actuator position setpoint.
