Abstract: A valve assembly for use with a catheter assembly is provided. The valve assembly includes a valve housing defining a longitudinal axis and adapted for fluid engagement with a catheter assembly. The valve housing has an internal passageway for flow of fluids relative to the catheter assembly. A valve member is at least partially disposed within the valve housing and defines a valve passage. The valve member is adapted for movement within the valve housing between an open position wherein the valve passage is in general alignment with the internal passageway of the valve housing to permit flow of fluids through the valve housing, and a closed position to substantially occlude the internal passageway of the valve housing. An actuation mechanism is selectively movable in a general longitudinal direction to cause corresponding movement of the valve member between the open position and the closed position.

Abstract: A bulk container anti-backflow ball valve is adapted for use with a bulk container having a tubular spout. The valve comprises a housing having an interior spherical chamber connecting an inlet port to an outlet port. The housing includes an inlet fitting about the inlet port for connection to the spout, in use. A valve element is rotationally supported in the interior chamber of the housing for movement between a valve open position and a valve closed position. The valve element comprises a spherical ball having a through bore defining a cylindrical interior passage. A wall extends across the interior passage separating an inlet side of the passage from an outlet side of the passage. The wall includes a through opening. An anti-backflow device is received in the outlet side of the passage aligned with the through opening and is movable between a seated position and a spaced position relative to the wall.

Abstract: A ball valve or the like for placement within a fluid conduit including: an element having a generally spherical geometry in fluid-tight relation to an interior diameter of the valve, and a fluid flow through the geometry, the element having an integral radial member extending externally through a slot to an outer housing, a degree of fluid flow through the fluid flow port changeable by rotation of the integral member and spherical geometry element. The valve also includes a solid cylindrical body having a longitudinal axis, a lower base integral with an outwardly extending part of the integral member of the generally spherical element and, at an opposite base thereof, a surface including at least a female recess engagable by a male extension of a wrench. The wrench may effect a full or partial opening or closure of by the incremental reciprocation, either forwardly or backwardly, of a handle.

Abstract: A valve in an engine exhaust system is disclosed. The valve can improve engine operation and reduce engine component degradation during cold engine starting. The valve may also be configured to provide different levels of restriction to exhaust gases flowing to a turbocharger turbine.

Abstract: A valve assembly includes: a valve body defining an annular shoulder that is formed with an annular shoulder groove; a hollow ball member disposed in the valve body; a sealing unit including an O-ring received in the shoulder groove and protruding outwardly of the shoulder groove; a stem extending into the valve body to connect with the ball member and formed with an annular flange seated on the O-ring; an annular packing seated on the annular flange; and an annular pressing member defining an annular neck that cooperates with the annular shoulder to sandwich the annular flange, the O-ring and the annular packing therebetween. The pressing member is coupled adjustably to the valve body, and is adjustable to move toward and away from the O-ring.

Abstract: A flow control device includes a hood, a ball valve, a sealing ring, and a handle. The ball valve is movably received in an interior receiving space of the hood and the ball valve is set in sealing engagement with the sealing ring. The ball valve and the handle located outside the hood are coupled together and are thus movable in unison with each other. The ball valve defines a flow passage. The hood forms a discharge opening. When installed on an opening of any kind of container, such as a PET bottle or a glass bottle, or an outlet tube of a water tank, by rotating the handle to move the ball valve, the flow passage can be selectively set in fluid communication with the discharge opening.

Abstract: The safety valve includes a first generally tubular body 12 and a second generally tubular body 14 each having flow paths therein when the bodies are mated. A ball 20 rotates between open and closed position in a first seat 30 and a ball centering member 32 provided for engaging the ball. An outer actuator sleeve 40 is rotatable with respect to the first and second bodies, and a connecting member 50 acts between the actuator sleeve and the ball to rotate the ball.

Abstract: The present invention relates to a direct flow tap for dispensing drinks, of the type with ball valve and actuated by a handle linked to said ball and provided with means suitable for limiting the rotation of said handle between two end positions, respectively corresponding to the closing and opening of said tap, characterized in that said means suitable for limiting the rotation of said handle is housed into the tap body. Said means suitable for limiting the rotation of said handle comprises a pin (14) provided with a prismatic portion (17) which alternately abuts for opening and closing, against a pair of jig locators (19) and (20) obtained on a fixed portion of the tap body.

Abstract: The present invention provides a flanged ball valve device which can be connected, as an integrated compact unit, to a pump at the valve flange end of the device by means of an integral flange and to various types of piping systems at the pipe end of the device by means of a pipe connector attached to the integrated valve housing of the device. The integral flange of the device is compatible with a variety of different sized pump flanges by virtue of a plurality of slotted bolt holes present in the integral flange. The valve handle provided in the present invention for opening and closing the spherical valve ball valve of the device is preferably U-shaped, thereby allowing increased surface area for insulation material of relative thickness to be wrapped around the integrated valve housing without disturbing handle rotation or covering the handle from view.
