A choke gate valve includes a housing that defines a fluid bore and a gate that includes a throttling orifice. The gate is configured to move within the housing between a throttle position in which the gate extends across the fluid bore to position the throttling orifice in the fluid bore to throttle a fluid flow through the fluid bore and an open position in which the gate does not block the fluid bore to enable a full level of the fluid flow through the fluid bore. The choke gate valve may be used as part of a choke gate valve system to transition between first fracturing operations for a first well and second fracturing operations for a second well without shut off of a pump.

The present invention includes a cartridge and system utilizing the cartridge that cools a computer. The cartridge first within a server stand and urges forced fluid into the computer.

A machine (1) for preparing a beverage (3) has a beverage processing unit (10,20) formed of a first processing unit member (10) and a second processing unit member (20) that delimit a chamber (21) and that are movable between a distant configuration in which a flavouring ingredient (2) is received in the chamber (21) and a proximate configuration in which the flavouring ingredient (2) is held and mixed with water (4) in the chamber (21) during beverage preparation. The machine includes: a water source for delivering the water (4) towards the beverage processing unit (10,20); a water guide (30) for guiding the water (4) between the water source and the chamber (21); a valve arrangement (50) for controlling a flow of the water (4) along the water guide (30); an actuator for actuating the valve arrangement (50) to control the water flow along the water guide (30); and a support structure (70) having a base (72) that is stationary during beverage preparation and that supports at least the valve arrangement (50). The valve arrangement (50) is rotatably mounted to the support structure (70) and driven in rotation by the actuator to control the water flow.

In accordance with at least one aspect of this disclosure, a flow control device can include, a first plate having one or more windows defining a flow path therethrough, a second plate configured to abut the first plate, and an actuator operatively connected to one or more of the first plate and/or the second plate. The actuator can be configured to drive the first plate and/or the second plate relative to one another to enlarge or reduce the flow path through the one or more windows in the first plate.

An exemplary gate valve includes a valve body having a gate cavity intersecting a through bore, the gate cavity extending through a first end of the valve body, an inner surface forming the gate cavity is angled outward from a center axis of the gate cavity to a gate cavity opening at the first end, and a gate positioned in the gate cavity and moveable between a closed position blocking flow through the through bore and an open position allowing flow through the through bore, the gate having a sealing face extending perpendicular to the through bore.

A gate valve and gate member for a gate valve, which may be used for hydrocarbon well fracturing operations with a fracturing fluid, or “frac fluid”, includes a seat, having a seat end face which is in sliding contact with a gate member that has a sealing face surface with at least one recess formed in the sealing face surface of the gate member.

A plug for retaining a filter screen in a fluid port of a servovalve, the plug comprises an annular body. The annular body comprises opposed first and second axial annular end surfaces. A radially inner surface extends between the first and second axial annular end surfaces and a radially outer surface extends between the first and second axial annular end surfaces. At least one recess is formed in the radially inner surface for receiving a tool for removing the plug from the port. A plurality of slots is formed in the first axial annular end surface and extends into the at least one recess for providing access for the tool to the at least one recess.

This disclosure relates to a shut-off valve, in particular a pipe-bridge slide valve, for a coking drum for the production of coke, having at least one pipe socket which has a first end for connection to the coking drum and a second end on which a slider is arranged for opening and closing the coking drum, wherein the pipe socket has a supply connection for filling the coking drum with a medium and a diaphragm which is arranged between the supply connection and the first end of the pipe socket and can be moved into a filling position and into an emptying position, wherein, in the filling position, a diaphragm opening is arranged in the region of the central longitudinal axis of the pipe socket for introducing the medium centrally into the coking drum, and, in the emptying position, the diaphragm opening has a larger passage area than in the filling position.

A discrete step, maximum flow-rate-selectable valve includes: (a) an entry tube with: (i) an exit with a single, off-center hole that lies on the circumference of a circle of radius “r” that is centered on the centerpoint of the exit, and (ii) an exterior surface having a portion with rotational symmetry, (b) a selector tube with: (i) an exit with a plurality of holes, each having a differing diameter and a center point that lies on the circumference of a circle of radius “r” which is centered on the centerpoint of the selector tube exit, and (ii) an interior surface configured to lie proximate said entry tube, exterior surface portion having rotational symmetry so as to assist in providing a water-tight seal between said tubes, and (c) a means to enable the selector tube to rotate in discrete steps around the entry tube.

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.
