    • An amperage control for an electrically operated valve having a coil. A process control apparatus generates a plurality of electrical operating data signals, each signal corresponding to an operating parameter of the valve. A valve control apparatus transmits voltage to the coil of the valve to control the operation of the valve, the valve control apparatus receiving at least one operating data signal generated by the process control apparatus. A current flow is created in the coil of the valve upon receiving voltage from the valve control apparatus. A current senses the flow of current in the electrically controlled valve, and creates an electrical signal responsive to the current flow in the coil of the valve. When the signal created by the current sensing apparatus is applied to the valve control apparatus, the valve control apparatus modifies the operation of the valve responsive to the signal created by the current sensing apparatus.
    • 具有线圈的电动阀的安培数控制。 过程控制装置产生多个电操作数据信号,每个信号对应于阀的操作参数。 阀控制装置将电压传递到阀的线圈以控制阀的操作,阀控制装置接收由过程控制装置产生的至少一个操作数据信号。 当从阀控制装置接收电压时,在阀的线圈中产生电流。 电流感测电控阀中的电流流动,并响应于阀的线圈中的电流产生电信号。 当由电流感测装置产生的信号施加到阀控制装置时,阀控制装置响应于由电流检测装置产生的信号来修改阀的操作。
