阀门定位器按输入信号分为气动阀门定位器、电-气阀门定位器和智能阀门定位器。气动阀门定位器的输入信号是标准气信号，例如，20~10OkPa气信号，其输出信号也是标准的气信号。电气阀门定位器的输入信号是标准电流或电压信号，例如，4~20mA电流信号或1~5V电压信号等，在电气阀门定位器内部将电信号转换为电磁力，然后输出气信号到拨动控制阀。智能电气阀门定位器它将控制室输出的电流信号转换成驱动调节阀的气信号，根据调节阀工作时阀杆摩擦力，抵消介质压力波动而产生的不平衡力，使阀门开度对应于控制室输出的电流信号，并且可以进行智能组态设置相应的参数，达到改善控制阀性能的目的。

按动作的方向可分为单向阀门定位器和双向阀门定位器。单向阀门定位器用于活塞式执行机构时，阀门定位器只有一个方向起作用，双向阀门定位器作用在活塞式执行机构气缸的两侧，从两个方向起作用。

按阀门定位器输出和输入信号的增益符号分为正作用阀门定位器和反作用阀门定位器。正作用阀门定位器的输入信号增加时，输出信号也增加，因此，增益为正。反作用阀门定位器的输入信号增加时，输出信号减小，因此，增益为负。

按阀门定位器输入信号是模拟信号或数字信号，可分为普通阀门定位器和现场总线电气阀门定位器。普通阀门定位器的输入信号是模拟气压或电流、电压信号，现场总线电气阀门定位器的输入信号是现场总线的数字信号。

Valve positioner is divided into pneumatic valve positioner, electro-pneumatic valve positioner and intelligent valve positioner according to the input signal. The input signal of the pneumatic valve positioner is a standard gas signal, for example, 20~10OkPa gas signal, and its output signal is also a standard gas signal. The input signal of the electrical valve positioner is a standard current or voltage signal, for example, a 4~20mA current signal or a 1~5V voltage signal, etc., which converts the electrical signal into an electromagnetic force inside the electrical valve positioner, and then outputs the gas signal to the toggle control valve. The intelligent electrical valve positioner converts the current signal output from the control room into the gas signal that drives the regulating valve. According to the friction force of the valve stem when the regulating valve works, the unbalanced force generated by medium pressure fluctuations is offset, so that the opening of the valve corresponds to the current signal output from the control room, and the corresponding parameters can be set in an intelligent configuration to achieve the purpose of improving the performance of the control valve.

According to the direction of action can be divided into one-way valve positioner and two-way valve positioner. When the one-way valve positioner is used in the piston actuator, the valve positioner acts in only one direction, and the two-way valve positioner acts on both sides of the cylinder of the piston actuator and acts in both directions.

According to the gain symbol of the output and input signals of the valve positioner, it is divided into positive valve positioner and negative valve positioner. When the input signal of the positive-acting valve positioner increases, the output signal also increases, so that the gain is positive. As the input signal of the reaction valve positioner increases, the output signal decreases, so the gain is negative.

According to the valve positioner input signal is analog signal or digital signal, can be divided into ordinary valve positioner and fieldbus electrical valve positioner. The input signal of the ordinary valve positioner is an analog air pressure or current or voltage signal, and the input signal of the fieldbus electrical valve positioner is a digital signal of the fieldbus.
