8202 8200H 8202H Electro-pneumatic positioner

Overview

8202 8200H 8202H Electro-pneumatic positioner is an instrument used with pneumatic control valves, which is imported from our factory imported into American Masoneilan company's products. It accepts the 4~20mA DC current signal output by the electric regulating instrument and then outputs a certain air pressure signal control.

The stroke of the regulating valve is controlled, and the stroke is changed in proportion to the current signal through the feedback system, so as to ensure that the valve is positively determined bit.

Feature

8202 8200H 8202H Electro-pneumatic positioner, According to the structure, the 8202 8200H 8202H electric-pneumatic valve positioner is divided into two categories: lever type and C b wheel type. They are equipped with linear pneumatic diaphragm actuators, IF pneumatic actuators and 35002 eccentric rotary valves, etc., which can overcome the valve stem The friction force eliminates the influence of the unbalanced force of the regulating valve, improves the valve's action speed, displacement accuracy and realizes split-range control, so it is widely used in the automatic control system of the petroleum, chemical, metallurgical, power station and light textile industries.

Note: Any special design or question of 8202 8200H 8202H Electro-pneumatic positioner, kindly contact the manufacturer for more details.
