A pressure gauge and/or relief valve which may be used in a single-use fluid system, such as a sterilizable fluid system. The pressure gauge and/or pressure relief valve may be formed of a disposable and/or sterilizable material, such as a non-metallic (e.g., polymeric) material. The material of the pressure gauge and/or pressure relief valve may be compatible with the material of a fluid-containing structure of the fluid system, such as to be bonded (e.g., welded) therewith. The fluid-containing structure may be retrofitted to integrate the pressure gauge and/or pressure relief valve therewith. The pressure gauge and/or pressure relief valve may have a simple configuration, such as a housing with a movable element therein. The movable element moves with respect to the housing to indicate pressure and/or to relieve pressure from within the housing and/or fluid-containing structure.

The disclosure relates to the technical field of hydraulic pneumatic systems, in particular to an electric control valve detection plug and an electric control valve signal detection method. The disclosure can accurately measure the electric control signal actually obtained by the valve, thus avoiding the risk of misjudgment. The disclosure has simple manufacture and convenient installation and disassembly.

Disclosed is a vacuum valve having a valve closure and having a drive unit which is coupled to the valve closure and which has at least one adjustment element. The vacuum valve furthermore has a position sensor, in particular a travel or distance sensor, such that a position of the valve closure and/or of the at least one adjustment element relative to a zero position, in particular an open position or closed position of the vacuum valve, can be measured.

An enhanced abandoned call recovery (“E-ACR”) process allows certain abandoned calls to be eligible for a callback call. An E-ACR assignment point defines which abandoned calls in an inbound campaign or interactive voice response (“IVR”) menu are eligible to be processed to determine whether the E-ACR callback should occur. The determination of whether a callback occurs involves various compliance tests, such as ensuring calling window, call attempts, and other regulatory concerns are addressed. Once a callback is determined to occur, it is associated with a specific campaign to ensure the called party is provided with agents having the skill set as defined for that assignment point. In this manner, only eligible callers receive an E-ACR callback, and further receive the callback in a compliant manner and handled by the same skill set of agents as would have been allocated to the caller had they not abandoned their call.

A vent valve flow fuse includes a valve cap with a valve cap cavity defined by one or more valve cap interior surfaces. The vent valve flow fuse includes a valve body with a valve body cavity defined by one or more valve body interior surfaces. The vent valve flow fuse includes a poppet configured to at least partially fit within the valve cap cavity and the valve body cavity. The vent valve flow fuse includes a spring configured to fit within the valve body cavity and to generate a resistive force against the poppet. The poppet is in a first position when fluid having a first amount of fluid pressure enters the valve cap cavity from a vent valve and engages the poppet. The poppet is in a second position when fluid having a second amount of fluid pressure enters the valve cap cavity and engages the poppet.

A valve state grasping system, a display device and a rotary valve, a valve state grasping program, a recording medium, and a valve state grasping method that enable efficient valve system monitoring and accumulation of information. The system includes a valve V, a sensor unit, a server including a database, a terminal device including a display unit, and a system control unit. The database includes a position information unit, a history information unit, and an inference information unit. The position information unit includes unique information and pipe attachment information, and the history information unit includes at least measurement information and diagnosis information. The system control unit accumulates information of the position information unit and information of the history information unit in association with each other and outputs predetermined inference information from the inference information unit based on information of the position information unit and information of the history information unit.

A steam oven for an aircraft galley. The steam oven includes a pipeline for supplying fluid comprising water or steam to a food preparation chamber of the steam oven. The pipeline is configured to receive water or steam from a source external to the steam oven and a valve configured to regulate the flow of said fluid through the pipeline. The valve has an open state in which the valve permits the flow of fluid through the pipeline and a closed state in which the valve prevents the flow of fluid through the pipeline. The oven also has control unit configured to actuate the valve between the open and closed states. The valve includes a sensor configured to detect an actual state of the valve 9, the sensor being independent of the control unit.

A method and system for controlling a fluid valve are described that avoid the effects of hysteresis. In hysteresis, the power signals associated with a valve position are different on the upstroke and downstroke. As a result, predicting the valve position can be difficult if you only know the current power signal. Instead of using upstrokes and downstrokes, a valve can momentarily be set to zero power, or a rest position when receiving a new command signal. This way the command signal is applied from a zero power or rest position, making the valve position more predictable and accurate.

Embodiments of the present disclosure relate to an apparatus, a system, and a method for detecting and indicating the operational position of a valve of wellsite equipment. The apparatus comprises a mount portion and a housing portion. The mount is operatively coupled to a non-moving part of the valve and the housing portion is configured to receive a sensor therewithin. The sensor is configured to detect the position of a moving part of the valve and to provide an output signal indicative of the position of the moving part of the valve. The position of the moving part of the valve is indicative of the operational position of the valve. The system comprises one or more such apparatus for detecting and indicating the operational position of one or more valves on a wellsite or well pad.
