Various embodiments of the present disclosure are directed to a method for producing a ball valve for regulating a fluid. In one example embodiment, the method includes the steps of: providing first and second housing parts of the valve housing, said first and second housing parts each including at least a central housing part and a connection end; providing a valve element shaped as a ball with at least one through-going aperture; arranging the first and second housing parts with the respective central part ends facing towards each other, and further arranging the ball at a position inside an inner space defined by the respective central parts; and welding the first and second housing parts together using a welding tool while performing an interrelated rotation about an axial rotation axis between the position of the first and second housing parts and the position of the ball.

A quick-connector comprises a first body portion, a second body portion, and a ball valve. The first body portion defines a first fluid channel. The second body portion defines a second fluid channel. The second body portion is coupled to the first body portion such that the first fluid channel is aligned with the second fluid channel. The first fluid channel and the second fluid channel form a fluid channel extending through the quick-connector. The ball valve is positioned in the fluid channel extending through the quick-connector. Movement of the first body portion and the second body portion relative to each other causes the ball valve to move between a flow position and a sealed position. In the flow position, the ball valve allows fluid to flow through the quick-connector. In the sealed position, the ball valve prevents fluid from flowing through the quick-connector.

A fluid management assembly and a thermal management system. The fluid management assembly has a first chamber and a first valve core located in the first chamber. The fluid management assembly has a throttle chamber. The first valve core has a conduction channel. The first chamber can communicate with other portions by means of a throttle channel or the conduction channel.

A valve for use in a gas turbine. The valve includes at least one valve body, at least first, second and third fluid delivery pipes positioned on the valve body, at least one outlet pipe positioned on the valve body and a rotatable spherical shutter inside the valve body (and including first and second distribution channels formed within the shutter so as to allow the outlet pipe to be selectively connected to one of the delivery pipes during rotation of the shutter.

A valve seat for a valve is disclosed, the valve seat facilitating cutting of a body located within the seat. The valve seat includes a sealing surface for sealing with a valve member and an annular cutting component having a plurality of cutting teeth. The cutting teeth are circumferentially spaced and each defines an elongate crest. A valve is disclosed having a housing with a bore), a valve member and the valve seat. The valve seat is arranged within the housing in communication with the housing bore. The valve member is movable relative to the housing between an open position and a closed position.

A ball valve apparatus with an improved linearity of fluid flow therethrough is provided. The ball valve includes a valve housing including a housing inlet and a housing outlet; a valve ball receivable within the valve housing, the valve ball having a bore therethrough, a ball inlet and ball outlet of the valve ball which are in fluid communication with the bore, a fluid flow path through the ball valve apparatus being defined at least in part by the housing inlet, housing outlet, ball inlet, ball outlet and the bore. There is also provided a valve stem engagable with the valve ball and. To control the fluid flow through the apparatus such that there is a linear or substantially linear relationship between at the angular position of the valve ball and the fluid flow through the apparatus, there may be provided at least one bridging element, positioned on the fluid flow path to alter a fluid flow thereacross and/or ball outlet, and/or at least one of the ball inlet and ball outlet may have a non-circular profile. A ball valve for such an apparatus is also provided, in addition to method of improving the linearity of fluid flow through a ball valve apparatus.

A valve includes a valve body provided with a plug, connected to an actuation system, an upstream duct, a downstream duct, and a purge duct provided with a shutter. The plug is movable in rotation about a longitudinal axis in the valve body, so that the rotation of the plug according to a first angular sector defines a flow between the upstream duct and the downstream duct, the rotation of the plug according to a second angular sector separate from the first angular sector shuts off the connection between the upstream duct and the downstream duct, and the rotation of the plug according to a third angular sector included in the second angular sector actuates the shutter so as to allow a flow from the upstream duct to the purge duct.

Embodiments provide a surge suppression device, a surge suppression system, and methods for operating the same. The surge suppression device includes a valve body and a plug. The plug is rotatably positioned in a hollow space of the valve body. The plug includes two surge suppression openings defining a fluid flow directed to surge suppression. Each of the two surge suppression openings includes a circular plate having a plurality of orifices. The plurality of orifices allows reduction of surge pressure when the water passes the first fluid flow path. The circular plate has a concave or convex geometry.

A ball valve that includes a ball comprising an integrally formed single-component body that defines an external surface; a fluid passage extending through the body, the fluid passage defining an internal surface; and a plurality of internal chambers formed within the body, each internal chamber of the plurality of internal chambers being spaced from the external surface and being spaced from the internal surface; wherein when the ball is subjected to one or more stresses, a stress concentration is created within a release-by-milling zone of the single-component body, the release-by-milling zone being adjacent to the plurality of internal chambers. The ball is at least partially manufactured using an additive manufacturing process.

A coolant control regulator assembly that comprises a plurality of modular housings, an actuator, and a plurality of ball valves. The actuator is operatively connected to at least one of the plurality of modular housings. Each of the modular housings comprises an internal cavity, at least one inlet port, and at least one outlet port. Further, each of the internal cavities includes one of the plurality of ball valves positioned therein. At least one of the plurality of ball valves comprises a plurality of apertures that are configured to align with the at least one inlet port and the at least one outlet port in certain rotational positions.
