A valve control assembly includes a valve body having an inlet adapted to be coupled to a source of process fluid having a first temperature, an outlet, and a fluid flow path extending between the inlet and the outlet, and a bonnet coupled to the valve body. An inlet port, an outlet port, an annular plenum, an inlet passage, and an outlet passage are integrally formed in the valve body or the bonnet. The inlet port is adapted to be coupled to source of media and the annular plenum is disposed between the inlet port and the outlet port, immediately adjacent a portion of the fluid flow path. The inlet passage directs the media from the inlet port to the annular plenum, which changes a temperature of the process fluid flowing through the fluid flow path from the first temperature to a second temperature different from the first temperature.

A plug for a fluid valve has a stem extending along an axis between a first end and a second end, a tip secured to the first end of the stem, a plug body mounted to the stem toward the second end relative to the tip, and a valve seat between the tip and the plug body. The valve seat has a sealing surface that extends past an outer perimeter of the tip and is sized to engage a valve ring of the fluid valve, the valve seat defining an annular space that permits radial movement of the valve ring relative to the axis of the stem to align with the valve ring as pressure is applied to the valve seat.

A pressure valve including a body including at least one admission opening and at least one discharge opening, a slide valve sliding in the body, the slide valve defining a chamber, with the body, and including a head arranged facing a seat of the admission opening, a spring pressing the head of the slide valve against the seat, a lip for applying the head to the seat. The head includes at least one hole bringing the chamber into communication with the discharge opening, each hole being arranged facing the seat and downstream from the lip in relation to the admission opening in order to reduce the pressure in the chamber by a Venturi effect when the slide valve is open.

An injection valve including a valve body defining an inlet, an outlet, and a fluid flow path connecting the inlet and the outlet. A valve shaft is disposed in the valve body, and a valve plug is operatively connected to the valve shaft. The valve plug is movable between an open position, in which the valve plug permits fluid flow between the inlet and the outlet, and a closed position, in which the valve plug limits flow between the inlet and the outlet. A seat ring defines a valve seat and is proximally disposed relative to the outlet of the valve body. The valve plug moves away from the valve seat when moving in a direction toward the valve body, and toward the valve seat when moving in a direction away from the valve body.

A valve having a valve housing and a shut-off element, the valve housing having a cavity for receiving the shut-off element, at least one inlet opening for a fluid to flow into the cavity and at least three outlet openings for the fluid to flow out of the cavity, the shut-off element having a guide body and being arranged in a movable manner at least partially in the cavity of the valve housing, the shut-off element having at least one shut-off projection for shutting off at least one of the outlet openings.

A globe valve, having a body through which a fluid circulation duct passes, the latter delimiting a fluid path with an inlet and an outlet, and a shutoff member housed inside a branch generally perpendicular to the body, this shutoff member being movable between a first end position, in which it shuts off the duct, and a second end position, in which it does not shut off the duct, wherein the duct has, on either side of the region of action of the shutoff member, a generally circular liquid circulation section, which is connected continuously, at least in the region of action of the shutoff member, to a section that is longer than it is wide, the body (2) not having an element that protrudes towards the inside of the duct.

A choke valve including a valve body defining an inlet defining a centrally disposed axis extending through the inlet, an outlet, and a chamber in fluidic communication with the inlet and the outlet, and a flow trim disposed within the chamber and having a side wall that defines a generally cylindrical shape, the flow trim defining a passage through the flow trim, a pair of diametrically opposing windows extending through the side wall, each window permitting fluid communication between the chamber and the passage in a direction orthogonal to the centrally disposed axis defined by the inlet, and a slot extending through the side wall, the slot being disposed substantially equidistantly between the pair of diametrically opposing windows orthogonal to the centrally disposed axis defined by the inlet and on a side of the flow trim opposite the inlet, the slot permitting containment of turbulence created by interaction of fluid flow through the windows.

A pipe stopper assembly includes a stopper fitting defining a fitting channel, the stopper fitting configured to be mounted to a pipeline; and a pipe stopper positioned in the fitting channel and comprising an expandable stopper body and a pressure assembly, the expandable stopper body configurable in an expanded configuration and a contracted configuration, the pressure assembly configurable in an open configuration and a closed configuration; wherein, in the open configuration, the expandable stopper body is biased to the expanded configuration, and in the closed configuration, the expandable stopper body is biased to the contracted configuration; and wherein, in the expanded configuration, fluid is prohibited from flowing through the fitting channel, and in the contracted configuration, fluid is permitted to flow through the fitting channel.

A trim assembly for a regulator can include a cage and a plug assembly. The cage can include a peripheral wall defining an opening and a plurality of cage apertures formed in the peripheral wall. The plug assembly can include a plug and a sealing element and can be configured to be moveably received within the opening so that the sealing element contacts an inner surface of the cage to vary a flow area through the plurality of cage apertures depending on the position of the plug.

A flow regulating switch valve includes a valve core that includes a switch assembly configured to drive a diaphragm assembly to open or close a water outlet, and also includes a flow regulating assembly that comprises a rotating ring, a sliding block, and a magnet. A control key is configured to control the switch assembly. The rotating ring is connected to the control key and includes an inclined plane that transitions from high to low and is configured to drive the sliding block to slide up and down such that the sliding block drives the magnet to move up and down. The magnet is configured to control the diaphragm assembly to regulate a size of the water outlet.
