摘要： Embodiments of a valve positioner (100) that can maintain operation of the control valve (102) despite failures in one or more components. These embodiments reduce downtime by allowing in-situ repair to occur on the valve positioner. In one embodiment, the valve positioner incorporates a by-pass component (120), which can utilize control input signals (e.g., a 4-20 mA signal) to energize one or more components (e.g., a current-to-pressure converter) to cause the control valve to modulate fluid flow without the digital microprocessor and/or related components.

摘要翻译： 尽管在一个或多个部件中发生故障，阀定位器（100）的实施例可以保持控制阀（102）的操作。 这些实施例通过在阀定位器上进行原位修复来减少停机时间。 在一个实施例中，阀定位器包括旁路部件（120），其可利用控制输入信号（例如，4-20mA信号）来激励一个或多个部件（例如，电流 - 压力转换器） 使得控制阀在没有数字微处理器和/或相关组件的情况下调节流体流量。
