Embodiments of a valve assembly and a method of detecting a leak in the same are provided herein. In some embodiments, a valve assembly for use with an enclosed environment includes a housing having an interior volume; a first valve having a first valve seat and a first sealing member at least partially extending through a first opening in the first valve seat in a closed position; a second valve disposed beneath the first valve and having a second valve seat and a second sealing member at least partially extending through a second opening in the second valve seat in a closed position; and a position sensing device coupled to an inner wall of the housing beneath the first valve and configured to detect a position of the first sealing member.

A faucet configured for touchless actuation that includes a spout; a mechanical valve configured to move between an open state and a closed state and having a member radially movable between an open position and a closed position in response to operation of the mechanical valve between the open state and the closed state; an electronic valve configured to move between an open state and a closed state; and a system configured to detect and communicate a state of the faucet in response to the position of the member.

A mounting assembly is provided for coupling a monitoring device to a valve assembly for relieving vacuum and over pressure conditions in a storage container. The valve assembly includes a body including a first port adapted to be in fluid communication with the storage container and a first valve seat disposed in the body, and a first control assembly including a first valve stem and a first closure element coupled to the first valve stem, the first closure member being movable relative to the first valve seat in response to changes in pressure in the container. The mounting assembly includes a mounting bracket adapted to be coupled to a portion of the body and a mounting tube configured to be slidably coupled to the mounting bracket. The mounting tube is adapted to receive the monitoring device, which is configured to obtain data indicative of the operation of the valve assembly.

A control valve (1) with a valve housing (13) through which a flow channel (14) runs with a flow cross section changeable by a closure unit consisting of a valve seat and a valve cone which is adjustable relative to the valve seat. An adjusting device has a sliding unit (2) with a sliding rod (21) adjusting the valve cone over an adjustment path and a drive device acting on the sliding rod and controlled by a controller. The controller has a measuring unit (4) which detects the adjustment path via a transmission unit. The transmission unit is provided with an adapter unit (3) comprising a replaceable structural unit, between the sliding unit (2) and the measuring unit (4), said adapter unit converting the adjustment stroke into a measurement stroke specified by the measuring unit (4) in a manner corresponding to a transmission ratio specified by the adapter unit.

An apparatus provides operator feedback in response to opening or closing of a valve or coupling, The apparatus may comprise: data storage means for storing at least one recommended opening or dosing event of the valve; sensing means for sensing operator actuation of the valve or coupling; and processing means for comparing the sensed actuation of the valve or coupling against the recommended opening or dosing event of the valve or coupling in real-time or near real-time, and outputting at least one operator feedback signal based on the comparison.

A device is configured to monitor a state of a rotatable handle of a valve when the device is attached to the rotatable handle. The device comprises a vector magnetometer configured to measure a magnetic field. The device comprises a processing unit configured to obtain from the vector magnetometer measurements of the magnetic field when the handle is rotated; calculate a change in the state of the rotatable handle based on a difference between the measurements of the magnetic field; and report the change in the state.

A control valve positioner mounting system is configured to include a control valve, a control valve positioner, an attachment lever translating movement of the control valve to the control valve positioner, and a control valve attachment system for attaching the control valve to the attachment lever using a spring loaded attachment affixed to the control valve and applying spring force to the attachment lever.

A method for monitoring a system with mechanically movable parts, preferably a valve system, wherein the system is preferably part of a technical plant, in particular a production plant, and wherein the system has at least one mechanically movable part, in particular a valve, where the method comprises a) acquiring indicators, which can be used for a technical characterization of a movement procedure of the mechanically movable part, via technical devices configured for the acquisition of the indicators and b) transferring the acquired indicators to an evaluation unit arranged outside the system to determine a technical status of the system.
