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.

The valve position of the actuator is maintained at a certain opening, and a certain signal pressure corresponds to a certain valve opening. The above action mode is positive action, if you want to change the action mode, just flip the cam, A direction into B direction, etc., you can.
The so-called positive-acting positioner means that the signal pressure increases and the output pressure also increases; the so-called counteracting positioner means that the signal pressure increases and the output pressure decreases.
A positive-acting actuator can realize the action of a counter-acting actuator as long as it is equipped with a reaction positioner; on the contrary, a counter-acting actuator can realize the action of a positive-acting actuator as long as it is equipped with a counter-acting positioner.

A brief introduction of smart valve positioner
Intelligent electro pneumatic valve positioners are widely used in the positioning control of pneumatic linear or angular stroke actuators. It converts the current signal output by the control room into a gas signal that drives the regulating valve. According to the friction force of the valve stem when the regulating valve is working, it offsets the unbalanced force produced by the fluctuation of the medium pressure, so that the valve opening corresponds to the control room output.
Detailed information of smart valve positioner
Intelligent electro pneumatic valve positioners are widely used in the positioning control of pneumatic linear or angular stroke actuators. It converts the current signal output from the control room into a gas signal that drives the regulating valve. According to the friction force of the valve stem when the regulating valve is working, it offsets the unbalanced force generated by medium pressure fluctuations, so that the valve opening corresponds to the current signal output by the control room. . And can carry on the intelligent configuration to set up the corresponding parameter, achieve the goal of improving the control valve performance.
