Various embodiments may include an actuating mechanism of a control valve of a valve control system with a control center sending a control signal, receiving a diagnostic signal, and subjecting the diagnostic signal to analytical diagnosis, and a valve with a valve rod. The actuating mechanism may include: a drive unit receiving the control signal and driving the valve rod; a sensor unit detecting a driving force applied to the valve rod and generating a driving force signal containing driving force data; a data processing unit receiving the driving force signal and conditioning the driving force signal, and then generating the diagnostic signal; and a communication control unit receiving the control signal sent by the control center, sending the control signal to the drive unit, receiving the diagnostic signal, and sending the diagnostic signal to the control center.

A valve control device includes a drive circuit for supplying a drive signal to an actuator adjusting an opening degree of a valve via a prescribed transmission line, generates a PWM signal on the basis of a target opening degree supplied from the outside and a sensor signal that indicates a real opening degree of the valve, and supplies the PWM signal to the drive circuit. The valve control device includes a disconnection detection unit which detects, on the basis of the PWM signal and a monitor signal of the drive signal, whether the transmission line is disconnected.

Methods and apparatus for coordinating operation of valves are disclosed. In some examples, an apparatus includes a valve controller to receive a first signal from a first control system to change an operating state of a valve, the valve controller is to provide the first control system exclusive control of the valve. In some examples, the valve controller is to receive a second signal from a second control system requesting permission to operate the valve, and send a response to the second control system indicating the first control system has exclusive control of the valve and has changed an operating state of the valve.

A controller for a valve assembly that is configured to meet requirements for use in hazardous areas. These configurations may regulate flow of instrument air to a pneumatic actuator to operate a valve. The controller may comprise enclosures, including a first enclosure and a second enclosure, each having a peripheral wall forming an interior space, and circuitry comprising a barrier circuit disposed in the interior space of one of the enclosures that power limits digital signals that exits that enclosure. In one example, the peripheral wall of enclosures are configured to allow instrument air into the interior space of the first enclosure but to prevent instrument air from the interior space of the second enclosure.

Methods and apparatus for controlling multiple valves as a single valve based on a coordinated control signal are disclosed. In some examples, an apparatus includes a valve controller to be operatively coupled to a first valve and a second valve. In some examples, the second valve is to be operatively positioned in series with the first valve. In some examples, the valve controller is to control a position of the first valve and a position of the second valve based on a coordinated control signal to be received by the valve controller.

A faucet system comprising a faucet; an electronic valve associated with the faucet; and a faucet controller associated with the electronic valve; wherein the faucet controller is configured to receive a faucet command from a command server; and actuate the electronic valve upon receiving the faucet command; wherein the command server is configured to receive a speech-based command from a natural language processing (NLP) server; generate the faucet command from the speech-based command and transmit the faucet command to the faucet controller; and wherein the NLP server is remote to the faucet.

A valve control device, which is designed as a valve control head and/or as a valve position regulator head, for controlling a valve drive and/or a fitting. The valve control device includes a control unit for interacting with a functional unit, which is designed as an actuator unit, sensor unit, signal unit and/or communication unit, wherein the control unit has a device driver for interacting with the functional unit, wherein the device driver provides a software interface, which can be addressed by an application program which can be run on the control unit and/or a remote procedure call, in order to effect an interaction with the functional unit.

Smart solenoid valve equipped with a communication and control kit comprising a wireless communication system as well as a PLC capable of controlling a plurality of system components, management and control method, software and user interface thereof for the management of said plurality of components controlled, in turn, by the smart solenoid valve.

A method for replacing a controller on a process device that avoids downtime on a process line. The method may include retrieving data from a first controller on a valve assembly, the data comprising information that defines values for operating parameters on the first controller, removing the first controller from the valve assembly, coupling a second controller to the valve assembly, and storing data on the second controller, the data comprising information that defines the values for operating parameters corresponding with the first controller.

Methods, systems, and apparatus, including computer programs encoded on a storage device, for performing leak detection. In one aspect, the method includes actions of obtaining water consumption data that is based on first sensor data generated by a connected water meter that is installed at a property, determining, based on the obtained water consumption data, (i) that a water leak is occurring at the property and (ii) a type of water leak that is occurring at the property, in response to determining (i) that a water leak is occurring at the property and (ii) a type of water leak that is occurring at the property, determining, based on a type of water leak that is determined to be occurring at the property, an operation to mitigate potential damages caused by the water leak, and initiating performance of the operation in order to mitigate potential damages caused by the water leak.
