摘要： A valve plug assembly includes a plug base, a first end of the base arranged for attachment to a valve stem, a second end of the plug base including a bore having a first portion and a second portion. The second portion of the bore is a conical terminus forming a first seat. A spacer has a through bore, a first end, and a second end, and is sized for insertion in the bore of the plug base and has a conical shape to engage the first seat, and the spacer also forms a second seat. A plug tip has a through bore and a conical end engaging the second seat and is arranged to engage the valve seat, and a cap screw extends through the plug tip and the spacer to mechanically secure the plug tip to the plug base.

摘要： A linear valve drive for connection to a valve body having a valve seat and at least one flow passage with at least one inlet and at least one outlet, comprises a drive housing with a drive unit accommodated therein, an actuating element axially shiftable by the drive unit and coupled with a valve closing element to be pressed against the valve seat, and optionally closing the flow passage, and a supporting unit surrounding the actuating element, which is designed to be attached to the valve body. A spring system loaded by actuating the linear valve drive is provided at the supporting unit, which in dependence on the compression path has different spring rates. Furthermore, a correspondingly equipped valve is described.

摘要： An austenitic stainless steel valve which is used at 100.degree. C. or higher is easy to operate at the beginning of use. The valve of the present invention has a valve body made from an austenitic stainless steel, and a stem adapted to be reciprocated to open and close the valve. The stem is made from a metal having a thermal expansion coefficient that is ten-thirteenths or less of that of an austenitic stainless steel. Such a metal may be a ferritic or martensitic stainless steel. With this arrangement, it is possible to restrict the compressive stress applied to the stem within an allowable stress for the material of the stem and thus to prevent the destruction of the seat or the bending of the stem. The valve can thus be used easily.

摘要： A wafer processing apparatus is provided with sealing ports between adjacent evacuatable chambers that are actuated to compress elastomeric seals carried by the valve sealing elements to differing degrees of compression, based on the amount of pressure differential between the chambers when sealed. The degree of compression is controlled so that less compression of the seal takes place when less is required to seal, such as with lower pressure differentials, thereby avoiding unnecessary fatigue and wear of and around the seals that would otherwise increase the generation of particulate contamination.

摘要： A high Cv bulk process valve, control system and method convey a process gas or liquid for manufacturing semiconductors through a fluid passage. The fluid passage contains an aerodynamically shaped expansion chamber within which a valve seat and a moveable poppet are arranged for opening and closing the fluid passage. The aerodynamically shaped expansion chamber includes a conically expanding entry and a conically contracting exit and is shaped such that the resistance to flow of the process gas or liquid through the fluid passage of the valve is very nearly the same as through a straight tubing having a cross-sectional area of an inlet to the valve and a length of the fluid passage through the valve. The valve can be added or subtracted from a gas or liquid control system with virtually no changes in pressure drop of flow restriction, when the valve is in the open position. The valve minimizes the energy consumed by valves in semiconductor gas systems.

摘要： A hermetically sealed valve includes a valve body having an annular seat adjacent the valve inlet with a frusto-conical surface diverging outwardly therefrom toward the valve outlet and a fixed diffuser assembly including a fixed disc guide and a slidable spring biased closure disc. The disc guide has a diverging frusto-conical surface spaced from the first surface to define a high efficiency annular diffuser flow passage. The fluid exposed surfaces of the disc are located upstream of the passage. The closure disc is actuated between an open position and a closed position by an axially movable valve stem acting on a flexible diaphragm. The pressure drop in the diffuser passage at high flow conditions establishes a force differential on the diffuser assembly acting toward the valve seat which is borne entirely by the disc guide thereby eliminating any pull down forces on the closure disc.
摘要翻译：气密密封阀包括阀体，该阀体具有邻近阀入口的环形座，其具有从其向外朝向阀出口向外扩散的截头圆锥形表面，以及固定扩散器组件，其包括固定盘引导件和可滑动弹簧偏压闭合盘。盘导向件具有与第一表面间隔开的发散的截头圆锥形表面，以限定高效的环形扩散器流动通道。盘的流体暴露表面位于通道的上游。闭合盘通过作用在柔性隔膜上的可轴向移动的阀杆在打开位置和关闭位置之间被致动。在高流量条件下，扩散器通道中的压降在扩散器组件上形成力，该扩散器组件朝向阀座完全由盘导向器承载，从而消除了封闭盘上的任何下拉力。
