摘要： A flow control valve including a valve body, stepper motor, and valve member. The valve member includes a poppet that can slide longitudinally within a bore of the valve body when the stepper motor receives electricity. A diaphragm, extending inwardly from the valve body to the valve member, deflects in response to movement of the valve member. A flow control needle, mounted to the poppet of the valve member, is at least partially received in an outlet port of the valve body. The flow control needle cooperates with an inner surface of the outlet port to define an outlet flow orifice that varies in size when the valve member moves between open and closed positions. In the closed position, a seat engagement surface of the valve member contacts a valve seat of the valve body to create a fluid-tight seal.

摘要： Embodiments of symmetric flow valves for use in a substrate processing chamber are provided herein. In some embodiments, a symmetric flow valve includes a valve body having sidewalls, a bottom plate, and a top plate that together define an interior volume, wherein the top plate includes one or more axisymmetrically disposed openings; a poppet disposed in the interior volume, wherein the poppet includes a central opening and a plurality of portions configured to selectively seal the one or more axisymmetrically disposed openings of the top plate when the symmetric flow valve is in a closed position; and a first actuator coupled to the poppet to position the poppet within the interior volume in at least an open position, where the poppet is spaced apart from the top plate to allow flow through the one or more axisymmetrically disposed openings of the top plate, and the closed position.

摘要： The invention relates to an electromagnetic valve having a valve housing (2) and a valve opening (29) with a valve seat (8) and an electric drive coil (3) and a magnetic yoke (11) and a longitudinal centre axis (14). The magnetic yoke (11) is assigned a metallic plate armature (5) which is mounted movably and has an armature disc (48). The armature disc (48) lies sealingly with a sealing surface (9) against the valve seat (8) in a first switching position of the valve, and opens the valve seat (8) in a second switching position of the valve. According to the invention, the valve seat (8) is configured on a valve component (18), wherein the valve component (18) has at least one valve opening (29) which lies at a radial spacing (r) from the longitudinal centre axis (14). The valve seat (8) of the valve opening (29), which valve seat (8) corresponds with direct body contact with the sealing surface (9) of the armature disc (48) of the plate armature (7), consists of metal.

摘要： A compressor valve may include a guard and a seat affixed thereto. The seat may have an inlet surface and an outlet surface opposite the inlet surface. A reconditioning limit indicator may be defined by or adjacent the outlet surface. The reconditioning limit indicator may be indicative of a maximum amount of material of the seat removable from the outlet surface during reconditioning of the seat. The reconditioning limit indicator may be a groove defined by the outer cylindrical surface of the seat, a portion of the outer cylindrical surface of the seat adjacent the outlet surface and having an outer diameter smaller than the outer diameter of the seat, or a predetermined shape of a predetermined depth machined on the outlet surface of the seat.

摘要： A sectional valve includes a working valve and a control valve, which controls the working valve. In order to permit a greater flexibility with respect to possible settings and/or use or operation by comparison to known solutions, it is proposed, for example, that the control valve have a control spring (34, 34′), which presses the anchor (5) onto the control valve seat (17), and against which the control coil (26) lifts the anchor (5) from the control valve seat (17), a permanent magnet (29), which in an actuation state is configured to hold the anchor (5) lifted from the control valve seat (17) by the core (35), and a magnet holder (28), in and/or on which the permanent magnet (29) is held in the actuation state, and which permits a distance from the permanent magnet (29), and/or that the control valve is configured to variably position the core (35) along a force generated by the control spring (34, 34′).

摘要： A coolant control valve unit includes a wall including a passage disposed at a predetermined position from one surface to another surface, a valve disposed to be inserted into the passage and open and close the passage according to a movement position, and an actuator opening and closing the passage through the valve by pushing or pulling the valve by using a stem connected with the valve, wherein one side and another side of the wall are formed to have a height difference in a movement direction or in an opposite movement direction so that a portion of the passage is opened and a remaining part of the passage is closed by the valve when the valve moves along the passage.

摘要： A butterfly-valve seat ring and fixing structure of the same, and an eccentric-type butterfly valve in which, the butterfly-valve seat ring has a flexible part (31) with a predetermined material thickness integrally and extendedly provided on one side surface of an inner diameter of a ring-shaped base body part (30) having a substantially rectangular shape in section and has a fixing part (32) integrally and extendedly provided on one side surface of an outer diameter of the base body part, has a recessed-shaped space part (40) provided between an outer circumferential surface (36) of the flexible part and an inner circumferential surface (37) of the fixing part, and has a seal contact part (35) provided to project at an inner diameter position of the flexible part. The seal contact part is positioned on an inner circumferential surface of the flexible part rather than a depth-side position of the space part.

摘要： An assembly includes a valve housing and a valve element such as a poppet valve. The valve housing includes a tubular duct and an annular valve seat disposed within the tubular duct. A first flowpath includes an inner bore of the annular valve seat. A second flowpath includes an aperture formed between the annular valve seat and the tubular duct. The poppet valve is configured to engage the annular valve seat and substantially close the first flowpath when the poppet valve is in a first position. The poppet valve is further configured to disengage the annular valve seat and at least partially open the first flowpath when the poppet valve is in a second position.
