A modular stop is provided for ball valves, such as those used as drill stem safety valves. The modular stop can be a replaceable component in valves for use with stems used to rotate a ball valve in the valve's body. The modular stop can bear the wear associated with the operation of ball valves and when the modular stop has exceeded its usable service life, it can be replaced without replacing the whole of the valve body. The modular stop can be used in new valve manufacture as well as in the retrofitting or remanufacturing of existing valves.

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 control device (100) having a housing (10) with at least one first port (16) and at least one second port (18, 20), wherein a valve body (30) is enclosed in the housing (10), the valve body (30) providing a fluid path (60) having a first path portion (62) proximal to the first port (16) and an opposing second path portion (64) in a distance from the first port (16) and proximal to the at least one second port (18, 20), the fluid path (60) being switchable between at least a first position (80) and at least a second position (82) in relation to the at least one second port (18, 20) by rotating the valve body (30) around the first main axis (22) of the at least one first port (16).

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 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 with a valve upper plate defining an inlet, a valve body defining an outlet, and a fluid passage. A closure member is disposed in the fluid passage between the inlet and the outlet and has a convex sealing surface and is rotatable between a closed position in which the closure member extends across the fluid passage with the convex sealing surface oriented towards the inlet and an open position in which fluid is able to flow through the fluid passage from the inlet to the outlet. A resilient sealing ring, when the closure member is in the closed position, is moveable between a first configuration in which the sealing ring forms a seal around a circumference of the convex sealing surface and a second configuration in which the valve comprises a circumferential gap between the convex sealing surface and the sealing ring.

A freeze tolerant ball valve for controlling the direction of expansion of freezing water within the ball valve is disclosed. The valve includes valve body inlet and the valve body outlet, and a spherical-shaped gate that has an axial fluid passage that extends through the spherical-shaped gate. The spherical-shaped gate can be rotated to block fluid communication between the valve body inlet and the valve body outlet. The valve body also has a first sidewall that is of a first sidewall thickness, and a sidewall having a boss that supports a concave cap that has a bottom wall that is of a bottom wall thickness, the bottom wall thickness being substantially thinner than the sidewall thickness. The cooperation of the passage through the spherical-shaped gate, the first sidewall with its first sidewall thickness positioned opposite to the bottom wall of the concave cap results in a valve that directs the effects of freezing on to the concave cap, which would fail first in the event of freezing. The cap can be easily and quickly replaced in the event of failure.

A ceramic lined valve comprising: i) a valve body (20) having an end connection (50) for coupling the valve in fluidic communication with a fluid flow conduit; v) a flow control member (22) within the valve body; characterized in that the ceramic lined valve further comprising: vi) a lining (30) within the valve body comprising a single piece of ceramic, wherein the lining extends from the flow control member to the end connection, the lining defining a valve seat abutting the flow control member, and vii) a ceramic covering (40) forming a coupling face of the end connection, separate from and juxtaposed to the lining.

A valve, comprising: a housing, a holder, a first valve body, a bearing, and a second valve body. The housing comprises a first housing part, a second housing part, and a neck connecting the first housing part and the second housing part, a first valve body cavity is formed in the first housing part. The holder is provided in the second housing part, the holder and the second housing part together form a second valve body cavity and a pump cavity, the holder and the neck together form a bearing accommodating part for enabling the first valve body cavity to be in fluid communication with the pump cavity. At the bearing accommodating part defined by the holder and the neck, a limiter is provided, the limiter extends towards the bearing, the bearing has a receiving part, and the limiter cooperates with the receiving part to restrict movement of the bearing.

A valve includes a housing, a valve body, a seal member mounting groove, and a seal member which is inserted into the seal member mounting groove from an insertion opening. The seal member is configured to come into contact with the valve body and a housing sealing surface when the valve body closes the housing opening so as to enable the valve body to close a housing opening in a sealed manner. The seal member mounting groove further includes a seal member limiting structure. The seal member limiting structure is disposed on a groove wall. The seal member limiting structure is configured to restrict movement of the seal member toward the valve body relative to the housing.
