The disclosed embodiments include systems and methods for energizing a ball valve seat assembly. In particular, the disclosed embodiments are directed toward energizing devices that generate linear or substantially linear energizing forces. In other words, as a seat of the ball valve translates axially with respect to a ball of the ball valve, the resulting energizing force that biases the seat ring back toward the ball is substantially directly proportional to the amount of axial translation. In certain embodiments, the linear energizing device includes an annular cantilevered v-shaped spring having a generally constant cross-sectional profile, including a pair of legs extending from a curved end.

A high pressure valves for the energy sector. Specifically, a first valve assembly and a second valve assembly being in communication of each other around a plug to allow for dynamic control over the pressure desired to set the plug.

A valve seat is provided for use in a rotary valve for use in highly corrosive and abrasive applications. The valve seat includes a seat body adapted to selectively engage a portion of the floating ball element. The valve seat also includes a sealing element disposed in a first groove formed in the seat body and adapted to prevent fluid flow between the seat body and the valve body. The valve seat further includes a first bearing disposed in a second groove formed in the seat body, and a second bearing disposed in a third groove formed in the seat body, wherein the second and third grooves are formed immediately adjacent the first groove such that the first and second bearings are disposed immediately adjacent the sealing element.

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.

In a valve housing modular system, different configurations for a globe valve arranged to adjust a process fluid flow are provided. The globe valve can have a globe valve member movable in translation along a stroke axis. The system can include a housing corpus with a process fluid inlet and outlet, a process fluid passage arranged therebetween, and an actuating opening to introduce the rod for actuating the globe valve member along the stroke axis; and a housing cover for covering the actuating opening. The system can include different adapters for the different functional/structural configurations.

A valve sealing arrangement, including a valve body, and a closing member including a closing member contact surface, and a seat, having a center axis, and provided with a sealing portion with a first sealing surface for making contact with the closing member and a back sealing portion with a second sealing surface for making contact with a surface of the valve body. The seat also includes a bellows between the first sealing surface and the second sealing surface wherein the bellows including bellow members wherein adjacent bellow walls form either inwardly open fold or outwardly open fold and wherein one or more of the bellow members extends in a direction that is oblique to the center axis of the seat.

A valve assembly includes a valve body and a valve member extending through at least a portion of the valve body. The valve assembly also includes a seat pocket forming an annular recess in the valve body and a seat arrangement positioned at least partially within the seat pocket. The seat arrangement includes a lower seat extending radially inward from the annular recess toward the valve cavity axis. The seat arrangement also includes an upper seat at least partially overlapping the lower seat, the upper seat extending radially inward toward the valve cavity axis to contact the valve member along a seat face. The seat arrangement further includes an interface seal positioned along an interface between the upper seat and the lower seat, the interface seal receiving a fluid pressure to drive the lower seat radially outward and into the annular recess.

A valve system comprising a valve chamber at a junction of an inlet port, an outlet port and a bypass port, the inlet port configured for fluid communication with exhaust gas, the outlet port configured for fluid communication with an inlet of a turbine, and the bypass port configured for fluid communication with an exhaust aftertreatment device; a rotary valve comprising a valve rotor which rotates about a valve axis within the valve chamber between a first position to permit gas flow through the bypass port and a second position to block gas flow. At least one of the valve rotor and the valve chamber comprises a protrusion and the other comprises a recess, wherein, in the first position, the protrusion and recess are spaced from one another, and, in the second position the recess receives the protrusion such that gas flow between the protrusion and recess is substantially prevented.
