摘要： A control valve for regulating flow of fluids has an actuator located in a control chamber connected to a valve body. The valve body defines a flow passageway passing through an opening. A plug is associated with the actuator such that movement of the actuator from a rertacted position towards an extended position displaces the plug towards the opening. The valve also includes a guide-and-seat insert which proivdes a valve seat interconnected with an attachment collar via a number of plud guides. When the plug is displaced b the actuator, the plug slides in contact with at least two of the plug guides. When the actuator moves to its extended position, the plug closes against the closure surface of the valve seat so as to block the passage of fluid from an inlet to an outlet of the valve.

摘要： The dual actuator valve of the present invention deploys both the primary and secondary actuator elements in a single, common control chamber. Therefore, the present invention provides a dual actuator valve having dimensions that are the same as, or similar to, the dimensions of a single actuator control valve. It will be appreciated that the actuator elements may be of diaphragm type or piston type actuator elements. The primary actuator element is mechanically linked to the valve plug and regulates the flow though the valve, while the secondary actuator element remains in a fully open position. Should the primary actuator element fail to operate the valve due, for example, to diaphragm rupture, failure of the primary control system, or any other reason, the secondary control system activates the secondary actuator element, which then effects movement of the primary actuator element thereby resuming flow regulation or closure of the valve as necessary.
摘要翻译：本发明的双致动器阀将主致动器元件和辅助致动器元件都布置在单个公共控制室中。因此，本发明提供了具有与单个致动器控制阀的尺寸相同或类似的尺寸的双致动器阀。应当理解，致动器元件可以是隔膜式或活塞式致动器元件。主致动器元件机械地连接到阀塞并调节通过阀的流量，而辅助致动器元件保持在完全打开位置。如果主致动器元件由于例如隔膜破裂，主控制系统的故障或任何其他原因而不能操作阀，则次级控制系统激活辅助致动器元件，其然后实现主致动器元件从而根据需要恢复阀的流动调节或关闭。

摘要： The valve seat of the present invention is configured for attachment to the valve housing after the valve housing has been coated with a protective coating. The valve seat is configured to grip the valve housing, thereby providing a secure attachment. In its simplest form, the valve seat and the valve housing are both configured with corresponding locking-ring grooves, and a locking-ring element is positioned so as to be at least partially deployed in both the valve seat locking-ring groove and the valve housing locking-ring groove simultaneously. It will be appreciated that the features of the present invention may be used to benefit with substantially any type and style of valve known in the art.

摘要： The pressure differential metering device of the present invention is generally deployed as a flow restrictor placed in the valve inlet so it will create a desired differential pressure to signal a pilot valve, for example, that drives the main valve to limit the flow rate through the valve. The pressure differential metering device of the present invention is deployed across the valve inlet port, with its central axis perpendicular to the direction of fluid flow. The flow restriction element of the present invention may be configured in a variety of sizes to create a desired restrictive cross section to the flow, thereby creating the required differential pressure signals for the valve instrumentation and control. The flow restriction element is configured with upstream and downstream apertures that are the openings to passageways to the corresponding upstream and downstream end-ports. The end-ports provide connection arrangements for the control system of the main valve instrumentation.
摘要翻译：本发明的压差计量装置通常作为流量限制器而配置在阀入口中，因此它将产生一个期望的差压信号，以便向先导阀发出信号，例如，驱动主阀以限制通过阀。本发明的压差计量装置横跨阀入口部分展开，其中心轴线垂直于流体流动方向。本发明的流量限制元件可以被配置成各种尺寸以产生对流动的期望的限制性横截面，从而产生用于阀仪器和控制的所需的差压信号。流动限制元件配置有上游和下游孔，其是通向相应的上游和下游端口的开口。端口为主阀仪表的控制系统提供连接装置。
