Abstract: A gastight shut-off device (1) which can be fitted between a supply pipeline (2) and a discharge pipeline (3), in the form of a ball valve, includes a housing (4), a housing flow passage with an inlet section (5) and an outlet section (6), a shut-off ball (7) with a shut-off ball flow passage (8), the shut-off ball (7) being mounted in the housing (4), if appropriate by means of two sealing rings (9, 10), and an actuating drive (11) for the shut-off ball (7); and inlet section (5) is designed in such a manner that it reaches into the shut-off ball flow passage (8), which is designed in such a manner that, in the event of the ball valve closing through rotation of the shut-off ball (7), that part of the inlet section (5) which reaches into the shut-off ball flow passage (8) is accommodated in a slot in the shut-off ball.

Abstract: A connection for joining an actuator to a valve comprising providing at least two flanged pins each in the body of the valve, providing at least two mating holes in a body of the actuator, the mating holes being aligned with the pins, providing a tapped hole transverse to each of the mating holes, the valve body being joined to the actuator such that the pins mate slidably with the holes, with set screws in the tapped holes engaging the flanged pins to axially tension the pins to draw the valve body into physical contact with the actuator.

Abstract: A barstock body fluid control valve comprising a barstock body of preselected material having an inlet end and an outlet end, and a preselected cross section defining the outer walls; a through machined main flow port located eccentrically on the inlet and the outlet ends wherein the main flow port eccentric location increases the available barstock thickness at one outer wall location and decreases barstock thickness in the opposite wall.

Abstract: A shut-off valve has a housing which is provided with a spindle bush. Located in the spindle bush is a movable spindle which is sealed with respect to the housing. The spindle is connected to a closure body disposed in the housing. The housing also has a recess, which extends around the spindle bush and is open to the interior of the housing. If the housing comes under internal pressure, the recess prevents corresponding deformation of the spindle bush. The latter can thus not become leaky under the action of the internal pressure.

Abstract: A valve assembly includes a valve and a gearbox. The valve includes a valve body having a drive opening and a mounting surface adjacent the drive opening. At least one mounting bore is formed in the mounting surface. At least one rigid pin is fixed to and projects from the mounting surface. A rotatable valve member is disposed in the valve body. A gearbox is operable to rotate the valve member through the drive opening. The gearbox includes a casing including a mounting wall positioned adjacent the mounting surface of the valve body. At least one mounting hole is formed in the mounting wall and is disposed adjacent the mounting bore. At least one pin hole is formed in the mounting wall and receives the pin. A drive hole is formed in the mounting wall and communicates with the drive opening. At least one fastener extends through the mounting hole and engages the mounting bore to secure the casing to the mounting surface. The pin resists relative rotational movement of the casing and the valve body.

Abstract: An improved metal ball valve for gas comprises a shutter housing chamber in which are provided two opposite sides or flats allowing to define annular recesses in which shutter sealing gaskets are substantially integrally engaged. The shutter weight is advantageously reduced by providing, for example, a bottom flattened portion and an axial hole, the shutter forming moreover, with the valve rod element, preferably a single-piece assembly, the rod-shutter assembly being held in the body of the valve by upsetting thereon the thinned end crown of a collar of the valve body.

Abstract: A valve having a valve closing member rotatably supported on one or more valve stems which are positionally infinitely adjustable is disclosed. The valve has a valve body defining a bore with an upper passageway extending from the bore. A valve stem extends coaxially through the passageway and rotatably supports the valve closing member in the bore. A cartridge is coaxially located within the passageway between the valve body and the stem. The cartridge captures the valve stem and engages the passageway via screw threads allowing for infinite positional adjustment. The cartridge also houses bearings for rotation of the stem and seals for sealing the passageway. The valve body may have a second passageway coaxially aligned with the first passageway in which a second valve stem is located. The second stem engages the passageway via screw threads allowing for infinite positional adjustment.

Abstract: A self cleaning and self draining valve. The valve may include a valve body that has an inlet port and an outlet port and a flow control chamber between the inlet and outlet ports wherein a flow control member is operably supported. The inlet and outlet ports may or may not be coaxially aligned. The valve body may have a bottom surface that is substantially coplanar with a bottom surface of the outlet port. The flow control member may have a flow passage that curves downwardly to the bottom of the flow control chamber. The valve may further include a movable seat member that is movably supported within the valve body such that a fluid passage is established between the seat and the flow control member when fluid is flowing through the valve and the passageway is closed when the flow control member is closed. The valve may further have an adjustable bonnet for selectively adjusting the position of the flow control member within the valve body.

Abstract: A spherical valve is formed of a main body, a cover, and a spherical body. The main body is of a hollow construction and is provided in the interior with a partition dividing the interior into an inner receiving cell and an outer receiving cell. The main body is provided at both ends with a threaded tubular portion in communication with the inner and the outer receiving cells. The cover is provided in the inner side with an annular body having an annular clamp seat. The spherical body is located between the main body and the cover and is provided in the interior with an L-shaped channel to be oriented in accordance with the opening and the closing of the spherical valve.

Abstract: A flow control assembly is provided with a cartridge which includes a body sized and shaped so as to be received in a housing of fluid handling apparatus, such as duplex strainers and diverter valves. The body has a first chamber and a second chamber adjacent to the first chamber. The first chamber includes a first fluid inlet and first and second fluid outlets, while the second chamber includes second and third fluid inlets and a third fluid outlet. A first valve is movably positioned in the first chamber. The first valve is movable between a first position, in which fluid passes from the first fluid inlet to the first fluid outlet, and a second position, in which fluid passes from the first fluid inlet to the second fluid outlet. A second valve is also movably positioned in the second chamber.
