YT1000L Electro Pneumatic Valve Positioner-Data Sheet (PDF Download)

Type YT-1000L Electro-pneumatic valve positioner is used for operation of pneumatic linear valve actuators by means of electrical controller or control system with an analog output signal of DC 4 to 20 mA or split Ranges.

Valve positioners are classified into pneumatic valve positioners, electro-pneumatic valve positioners and smart valve positioners according to input signals.
The input signal of the pneumatic valve positioner is a standard gas signal, forexample, a 20~100kPa gas signal, and its output signal is also a standard gas signal. The input signal of the electropneumatic valve positioner is a standard current or voltage signal, for example, 4-20mA current signal or 1~5V voltage signal, etc.
The electric signal is converted into electromagnetic force inside the electro pneumatic valve positioner, and then the air signal is output to the toggle Control valve. The intelligent electro pneumatic valve positioner converts the current signal output from the control room into the gas signal for driving the regulating valve. According to the friction force of the valve stem when the regulating valve is working, the unbalanced force generated by the fluctuation of the medium pressure is offset, and the valve opening corresponds to the control The current signal output by the chamber can be configured intelligently to set the corresponding parameters to achieve the purpose of improving the performance of the control valve.

According to whether the valve positioner has CPU or not, it can be divided into ordinary electro pneumatic valve positioner and intelligent electro pneumatic valve positioner. Ordinary electro pneumatic valve positioners do not have a CPU, so they are not intelligent and cannot process related intelligent calculations.
The intelligent electropneumatic valve positioner has a CPU, which can process related intelligent calculations, for example, it can perform nonlinear compensation of the forward channel, and the fieldbus electro pneumatic valve positioner can also be equipped with PID and other functional modules to realize the corresponding calculations.
It can also be classified according to the detection method of the feedback signal.
For example, valve positioners that use mechanical linkage to detect valve position signals; valve positioners that use Hall effect to detect displacement of valve stems; valve positioners that use electromagnetic induction to detect valve stem displacement.
