A seal arrangement for use in a fluid control valve includes: a first seal configured to sealingly abut against an actuatable valve body of the fluid control valve; a second seal configured to sealingly abut against a valve housing of the fluid control valve; and an elastically deformable intermediate spacer, arranged between the first seal and the second seal and configured to elastically space the first and second seals apart. At least in an installed state of the seal arrangement in the fluid control valve, the first seal and the second seal are joined to one another in positively locking fashion in an axial direction of the seal arrangement.

A slip seal having a double profile provides two barriers to withstand the working pressure of a medium acting against the slip when a plug valve is in the closed position.

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 rotary-type valve device includes: a tubular valve having an inner passage and opening parts opened in an outer circumferential wall from the inner passage toward an outward side in a radial direction; a housing accommodating the valve and turnably supports the valve; a tubular passage member assembled in the housing such that the passage member abuts on the outer circumferential wall of the valve and defining a radial-direction passage; and a biasing spring biasing the passage member toward the outer circumferential wall The passage member includes an abutting member abutting on the outer circumferential wall, and an intervening member having an annular pressing part intervening between the abutting member and the biasing spring and partially pressurizing the abutting member. The abutting member includes an annular sealing surface aligned with the annular pressing part in a biasing direction of the biasing spring.

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 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.

An electric valve, comprising a housing component and a valve body component, wherein the housing component is fixedly connected to the valve body component; a control component comprises a motor, and a control component is provided in an inner cavity of the housing component. With respect to the background art, the influence of moisture on the motor can be reduced.

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.
