EP7000 Series Electric Valve Positioner EP7111 EP7112 E, EP7000 Series Electric Valve Positioner (hereinafter referred to as Locator) is the introduction of latest technology, developed by our factory's new products. Its technical performance has reached the same level of foreign similar products. The National Instrument Inspection Station Explosion-proof safety inspection, state-level explosion-proof certificate. With pneumatic valve, pneumatic valve, pneumatic valve, etc. supporting the use of the electric signal conditioner converts the DC current air pressure control valve movement, but also with the displacement of the valve or switch for feedback, which constitutes the closed-loop control circuit. To improve the accuracy of the valve control. To overcome the friction of the valve stem packing. Medium pressure to overcome the imbalance force of the valve. Improve the speed of valve movement, to achieve sub-process control (banded signal), can change the mode of action of the valve, to control various types of non-standard operating pressure of pneumatic actuators. It is widely used in petroleum, chemical, power, metallurgy, light industry and other industrial sectors.
