Example embodiments disclose a valve seat that encloses a fluid passage for passage of a fluid from a fluid chamber, and a holding element that exerts a holding force on a valve body, the holding force acting in a direction towards a valve seat. In the event that the fluid acts on an effective surface of the valve body with a force or a pressure above a limit value, the valve body moves away from the valve seat. In the event that the fluid acts on an effective surface of the holding element with a force or a pressure above a limit value, the holding force acting on the valve body decreases. In doing so, the fluid acts on the holding element more strongly and/or earlier than on the valve body.

Apparatus and method for capturing and combusting all vented natural gas and control natural gases from pneumatic controllers for oil field equipment are described. After an oil or gas well is drilled and completed, separators or treaters, as an example of oil field equipment, are installed on the surface to separate the liquids (oil/condensate and water) and gases (natural gas/methane). Pressure control valves, liquid control valves, temperature control valves, and the like, are pneumatically operated by the natural gas/methane that the separator is processing for sale, when electricity is not available to provide power for these operations. Presently, the pneumatic controllers discharge the pneumatic gas/methane to the atmosphere.

A valve block includes a fluid-transfer plate with multiple inlet bores connecting to a common inlet channel, and multiple outlet bores connecting to a common outlet channel. The inlet bores and the outlet bores are arranged in a curved shape. The valve block also includes a pressure plate and diaphragm aligned and connected to the fluid-transfer plate in a way that allows pressurized material in the pressure plate to control the state of the channels formed by the inlet and outlet bores.

A pressure relief valve includes a bowl-shaped housing having a bottom wall and an annular sealing wall, wherein the sealing wall delimits a valve through-opening, and a jacket wall. A cover is provided for covering a housing opening of the housing opposite to the bottom wall, having a diaphragm holder extending in the direction of the bottom wall. A diaphragm is provided for covering the valve through-opening, wherein the diaphragm is connected to the diaphragm holder and disposes the diaphragm holder sealingly on the annular sealing wall such that the valve through-opening is closed.

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 valve assembly and an ink cartridge with the valve assembly are provided. The valve assembly includes a valve cover, a valve base, a diaphragm and a transfer column. The valve cover is disposed on the valve base to define a valve cavity, and the diaphragm is disposed between the valve cover and the valve base and configured for separating the valve cavity into a first deformable cavity and a second deformable cavity independent with each other. The transfer column is fixed in the valve cavity and penetrates through the diaphragm, and at least one of the transfer column and the diaphragm is provided with a passage. The diaphragm moves relative to the transfer column due to a pressure difference between the first deformable cavity and the second deformable cavity, resulting in opening or cutting off communication between the first deformable cavity and the second deformable cavity by the passage.

Provided are a power element and an expansion valve using same that are capable of suppressing local deformation of a diaphragm or the like while ensuring the transfer efficiency of a refrigerant. A power element includes a diaphragm; an upper lid member that is overlapped on one surface in the vicinity of the outer circumference of the diaphragm and forms a pressure working chamber PO with the diaphragm; a receiving member that is overlapped on another surface in the vicinity of the outer circumference of the diaphragm and forms a refrigerant inflow chamber LS with the diaphragm; and a stopper member housed in the refrigerant inflow chamber LS and in contact with the diaphragm, wherein a plate thickness near a support point of the diaphragm is thicker than a plate thickness at a central portion of the diaphragm.

A fluid control device, capable of detecting leaks even if the leaks is slight, is provided. The fluid control device includes a valve body in which the flow path is formed, a diaphragm isolating a closed space from the flow path, a bonnet forming the closed space between the diaphragm and providing a penetration hole connected to the closed space and penetrated to be able to vertically move a diaphragm retainer, the diaphragm retainer vertically moving in the penetration hole to press the diaphragm and providing an increased diameter portion not to be removed from the penetration hole, a pressure sensor detecting a pressure inside of the closed space, and an elastic body interposing between the increased diameter portion of the diaphragm retainer and the bonnet inside of the closed space and elastically expanding and deflating between the increased diameter portion of the diaphragm retainer and the bonnet as the diaphragm retainer vertically moves.

A valve for a vacuum apparatus includes a first housing element and a second housing element wherein an outer chamber is defined by the first housing element and the second housing element. The first housing element has a first opening and the second housing element has a second opening in fluid communication with the first opening via the outer chamber. An inner chamber is defined by the first housing element and the second housing element wherein a membrane is disposed in the inner chamber. A sealing element is connected to the membrane and is moveable from a first position to a second position wherein in the first position the sealing element closes the first opening in a leak-tight manner and in the second position the sealing element opens the first opening to allow a gaseous medium to flow through the valve.
