A flow control valve assembly has at least one manifold having an inlet flow port, an outlet flow port, and a flow channel provided there between, the flow channel having an inlet chamber, a variable area chamber and an outlet chamber, with fluid flowing from the inlet flow port to the inlet chamber, the variable area chamber and the outlet chamber, in that order, before exiting the outlet flow port. The flow control valve assembly further includes a float assembly having a float extending through the flow channel and which is limited for its movement inside the variable area chamber, a connecting rod extending through the flow channel and which has an upper end that is connected to the float and a lower end that is connected to a magnet. A measuring device is positioned outside the fluid chamber at the bottom of the at least one manifold, and spaced apart from the magnet.

A valve assembly including a tubular having a first end, a second end, and an intermediate portion extending therebetween. The second end includes one or more openings. A pin member extends radially outwardly of the intermediate portion of the tubular. A valve member is arranged about the tubular. The valve member includes a first end portion, a second end portion and an intermediate section extending therebetween. The second end portion includes a valve element that registers with the one or more openings. An actuator sleeve is mounted to the first end of the valve member and extends about the tubular. The actuator sleeve includes a first end section, a second end section, and an inner surface extending therebetween. The inner surface includes a plurality of J-slots that are selectively receptive of the pin member to establish a position of the valve element relative to the one or more openings.

A supplying apparatus of granular material including a storage container storing granular material and a supplying portion having a columnar valve body sliding along an opening direction of a guide hole provided for the storage container. The supplying portion supplies granular material to a supply destination; the valve body includes a material supplying passage penetrating the valve body so as to provide an inlet and an outlet on a side circumferential face and includes a closing portion closing the guide hole when the valve body is at a closed position, the closing portion being provided in the guide hole; and the material supplying passage slants in such a manner that the inlet opens in the storage container and the outlet opens outside the storage container when the valve body is at a supply position supplying granular material.

A fluid control valve having a body, a seat ring, a valve cage adjacent the seat ring, a first valve plug assembly positioned within the valve cage, and a second valve plug assembly positioned within an axial bore of the first valve plug assembly. The first valve plug assembly has radial apertures in fluid communication with the axial bore and a first valve plug including the axial bore and a throttling port in fluid communication with the axial bore. The first valve plug assembly is movable between a closed position, in engagement with the seat ring, and an open position, spaced apart from the seat ring. The second valve plug assembly has a second valve plug that is movable between a closed position, in engagement with the first valve plug, and an open position, spaced apart from the first valve plug.

A regulator includes a body, a first cage positioned in the body, a diaphragm positioned within the body, and a second cage operatively connected to the diaphragm. The body has an inlet, an outlet, and a passage formed between the inlet and the outlet and the first cage is positioned adjacent the passage. The second cage moves with the diaphragm and is positionable on a first side of the diaphragm, opposite the first cage, or on a second side of the diaphragm such that the second cage is positioned within the first cage and is movable relative to the first cage.

A flow control module is provided. The flow control module includes a housing as well as an on/off solenoid assembly and a proportional solenoid assembly mounted to the housing. A flow body is situated within the housing and is interposed between the on/off solenoid assembly and the proportional solenoid assembly. The flow body provides for flow management of a flow of fluid through the housing.

A valve assembly used with a process chamber for depositing a film on a wafer. A valve body surrounds a bore and includes an inlet, a first outlet and a second outlet, at least one of them exiting into the process chamber. A piston includes a first section having a first flow path, and a second section having a second flow path. A linear motion actuator is adapted to couple with the piston and controls linear movement of the piston through the bore between a first position and a second position. In the first position, the first section of the piston is aligned with the inlet such that fluid flows to the first outlet via the first flow path. In the second position, the second section of the piston is aligned with the inlet such that fluid flows to the second outlet via the second flow path.

A flow control valve assembly has at least one manifold having an inlet flow port, an outlet flow port, and a flow channel provided there between, the flow channel having an inlet chamber, a variable area chamber and an outlet chamber, with fluid flowing from the inlet flow port to the inlet chamber, the variable area chamber and the outlet chamber, in that order, before exiting the outlet flow port. The flow control valve assembly further includes a float assembly having a float extending through the flow channel and which is limited for its movement inside the variable area chamber, a connecting rod extending through the flow channel and which has an upper end that is connected to the float and a lower end that is connected to a magnet. A measuring device is positioned outside the fluid chamber at the bottom of the at least one manifold, and spaced apart from the magnet.

The invention relates to a control fitting having a two-way cross-fitting, which has an inlet connecting piece, an outlet connecting piece and a passage connecting piece, and having a control element which is arranged in a guide connecting piece of the control fitting so as to be movable between an open position and a closed position, wherein the outlet connecting piece, in the open position of the control element, communicates with the inlet connecting piece and, in the closed position of the control element, is blocked relative to the inlet connecting piece and the passage connecting piece communicates with the inlet connecting piece both in the open position and in the closed position of the control element, and wherein the guide connecting piece has, on an end remote from the outlet connecting piece, an opening for receiving the control element.

The present disclosure provides an atomization device including a liquid storage cavity, a liquid injection opening, and an injection structure; the injection structure includes an injection tube and a sealing member; the injection tube runs through the liquid injection opening and extends into the liquid storage cavity, and a liquid inlet is formed in a side wall of the injection tube; the sealing member is arranged on one end of the injection tube in the liquid storage cavity; the sealing member is sealed from an inner wall of the liquid storage cavity, and separates the liquid inlet from the liquid storage cavity. When the injection tube is pushed into the liquid storage cavity, the liquid inlet moves into the liquid injection opening to communicate with the liquid storage cavity. When the injection tube is not pushed, the injection tube separates the liquid inlet from the liquid storage cavity.
