    • A valve apparatus may include a control valve including valve body having an inlet, an outlet, and a flow path. A rotational valve stem may extend along a longitudinal axis, the valve stem having a top portion and a bottom portion, the valve stem operatively coupled to a control element movably disposed in the flow path. A yoke may be attached to the valve body and arranged to operatively couple the valve body to an actuator, the yoke including a first bracket having an aperture and a second bracket having an aperture. A bushing may be arranged to align an actuator shaft of the actuator to the longitudinal axis of the valve stem, the bushing having a first portion and a second portion, the first portion engaging within the aperture of the first bracket and the second portion engaging the aperture of the second bracket.
    • 阀装置可以包括控制阀,该控制阀包括具有入口,出口和流动路径的阀体。 旋转阀杆可沿纵向轴线延伸,阀杆具有顶部和底部,阀杆可操作地联接到可移动地设置在流动路径中的控制元件。 轭可以连接到阀体并且布置成将阀体可操作地联接到致动器,轭包括具有孔的第一支架和具有孔的第二支架。 衬套可布置成将致动器的致动器轴与阀杆的纵向轴线对齐,衬套具有第一部分和第二部分,第一部分接合在第一支架的孔内,并且第二部分接合 第二个支架的光圈。

    • An impedance seat (10) having an impedance element (19) that can be mounted in conjunction with a seat in a ball valve (52). The impedance seat has a concave surface (16) matching the curvature of the ball (76) and a plurality of flow paths (18) formed through it. An impedance assembly can have a plurality of stacked plates (34) that define the flow paths. The impedance seat can have a full flow window (104) having a radius that matches the profile of a flow bore (86) of the ball valve in an intermediate position. The impedance seat can be easily fabricated to provide improved impedance characteristics, and can be used in an original ball valve, or in a retrofit for an existing valve.
    • 一个具有阻抗元件(19)的阻抗座(10),阻抗元件(19)可以与球阀(52)中的座位一起安装。 阻抗座具有与球体(76)的曲率相匹配的凹面(16)和通过其形成的多个流动路径(18)。 阻抗组件可以具有限定流动路径的多个堆叠板(34)。 阻抗座可以具有完全流动窗口(104),其具有与处于中间位置的球阀的流动孔(86)的轮廓匹配的半径。 阻抗座可以容易地制造以提供改进的阻抗特性,并且可以用于原始球阀或用于现有阀的改进。
