A normally closed valve comprising: a seat that has a fluid inlet and a fluid outlet; a diaphragm, an external handle and an internal safety mechanism operationally coupled to the external handle and the diaphragm. The valve allows forcing the handle in a first direction, thereby moving the internal safety mechanism through at least a first and subsequently a second stage. During the first stage: the diaphragm is pressed onto the seat, flow of pressurized air through the internal safety mechanism is blocked, and air pent in the valve is vented, causing the valve to be and remain in a closed state. During the second stage: flow of pressurized air through the internal safety mechanism is allowed, the pressurized air after passing therethrough, acting against the pressing of the diaphragm onto the seat, and a venting of air is reduced, causing the valve to be and remain in an open state.

A pipe stopper includes an expandable stopper body configurable in an expanded configuration and a contracted configuration, the expandable stopper body comprising a shell defining a stopper cavity and further defining an opening providing fluid communication to the stopper cavity through the shell; a pressure assembly received in the stopper cavity and defining a housing cavity; and a valve stem defining a stem fluid pathway, the valve stem movable between an open position and a closed position.

A tamper resistant device for an appliance for preventing unauthorized access to and manipulation of the controls for a water heater or the like. The tamper resistant device for an appliance includes a support assembly adapted to secure about a back of a control unit of an appliance and a cover member removably securable to the support assembly and adapted to cover the control unit of the appliance.

An industrial automation system includes a first computing device that communicatively couples to a second computing device via a communication network. The first computing device receives image data capturing a visual representation of industrial automation equipment in operation via the communication network, in which the image data is acquired by the second computing device; determines an identity of the industrial automation equipment based at least in part on the image data; determines relevant information regarding the industrial automation equipment based at least in part on the identity of the industrial automation equipment; and instructs the industrial automation equipment, the second computing device, the first computing device, the industrial automation system, a user, or any combination thereof to perform one or more operations in the industrial automation system based at least in part on the relevant information.

A pipe stopper includes an expandable stopper body comprising a shell defining a stopper cavity and configurable in an expanded configuration and a contracted configuration; a pressure assembly received within the stopper cavity; and an actuation arm pivotably connected to the shell and pivotably connected to the pressure assembly, the actuation arm configured to move the expandable stopper body between the expanded configuration and the contracted configuration.

In one embodiment, a non-transitory computer readable medium may include computer-executable instructions that, when executed by a processor, may receive a first set of data associated with a user, receive a second set of data associated with one or more lockout procedures performed by the user, receive a request to actuate a locking mechanism of an electronic lock configured to prevent a machine in an industrial automation application from being operational, and send a signal to the electronic lock to actuate the locking mechanism when the second set of data indicates that the lockout procedures have been performed by the user and the data corresponds to an authorized user.

In one embodiment, a system includes an industrial automation device and a computing device. The computing device includes a display configured to display a set of procedures. The computing device also includes a processor configured to receive an input after each step of the set of procedures is performed by a user, analyze the input in view of one or more scoring factors associated with performance of the at least one step, determine a first score for the user, the industrial automation device, or both based on the scoring factors, and store the first score in a cloud-based computing system. The cloud-based computing system is configured to provide access to the first score.
