Further, the coolant control ball valve comprises a flow diverter positioned adjacent the valve element. The flow diverter allows for coolant to reach a minimum velocity around the expansion element.

An actuating mechanism includes an actuating shaft, an actuated member, and an engaging and disengaging structure. The actuating shaft is configured to be rotatable. The actuated member can be actuated by the actuating shaft to rotate. The engaging and disengaging structure includes an actuating structure provided on the actuating shaft and an actuated structure provided on the actuated member. When the actuating structure engages with the actuated structure, the actuating structure can drive the actuated structure to rotate, such that the actuating shaft can drive the actuated member to rotate. Further, a set of actuating and actuated structures of the actuating mechanism can rotate and stop according to set angle requirements, such that a valve body can be actuated to connect and disconnect different fluid passages as required.

A valve assembly used in a manifold system fix processing fluid samples includes a body, a valve member, and a coupling assembly. The body defines a fluid passage and a valve passage in communication with the fluid passage and receiving at least a portion of the valve member therein. The valve member is selectively movable over a range of travel between an open position, in which fluid can flow through the fluid passage, and a closed position, in which the valve member occludes the fluid passage. The coupling assembly includes a coupling member and a retention lug. The retention lug is connected to one of the body and the coupling member. The other of the body and the coupling member defines a lug raceway configured to removably receive the retention lug therein to removably mount the coupling member to the body with the valve member being movably retained therebetween.

A regulating valve has a housing, a first valve body, a second valve body, a third valve body, a fourth valve body, and an actuating shaft. The housing has a first cavity and a second cavity. The first valve body is disposed in the first cavity. The second valve body is disposed in the first cavity, and the first valve body and the second valve body can rotate about a first axis X. The third valve body is disposed in the second cavity. The fourth valve body is disposed in the first cavity, and the third valve body and the fourth valve body can rotate about a second axis Y. The actuating shaft is rotatably disposed in the first cavity, and the actuating shaft can selectively drive one or more of the first valve body, the second valve body, the third valve body, and the fourth valve body to rotate.

A valve device includes a washing inlet, outlets, a switching inlet, a movable switching member, and a conversion engagement portion. The outlets is configured to be in communication with the washing inlet. The movable switching member is movable in a linear direction based on a pressure of a fluid that is fed to the switching inlet. The conversion engagement portion converts linear movement of the movable switching member into a rotation of a predetermined angle. The valve device is configured to switch which of the outlets is in communication with the washing inlet in accordance with a rotation angle of the movable switching member

Disclosed is a gas discharge apparatus for liquefied hydrogen storage tanks, the gas discharge apparatus including a receptacle mounted to a liquefied hydrogen storage tank, the receptacle having a stationary valve configured to be opened by external force mounted therein, a multistage opening and closing device coupled to the receptacle such that the position of the multistage opening and closing device is adjustable, the multistage opening and closing device being configured to be opened by reaction force transmitted from the receptacle when moved relative to the receptacle, the multistage opening and closing device having a sliding valve configured to push open the stationary valve in the state in which the multistage opening and closing device is open, and a manipulation unit configured to move the multistage opening and closing device relative to the receptacle such that the sliding valve and the stationary valve are sequentially opened.

A ball valve assembly configured to be controlled remotely can be included in a system for fracking a well. Ball valve assemblies of the present disclosure can include a main body having a bore for transmitting fluid therethrough and a ball disposed within the main body and having a throughbore, the ball being hydraulically rotatable within the main body for rotation between an open state and a closed state of the ball. Such ball valve assemblies can include other components such as one or more wipers on and in contact with an external surface of the ball throughout rotational operations of the ball to minimize debris from interfering with the valve, and/or pressure equalizing valves to adjust fluid pressure above and below the ball of the assembly, for example. Further, the ball vale assembly can be adapted to operate more safely by including a directional lock plate.
