HRVO電動O形切斷球閥可直接接收計算機或工業儀表等輸出的4～20mADC或1～5VDC控制信號，220VAC電源,根據閥位反饋信號與設定值比較偏差對執行機構驅動電機進行智能步距調整（PID調節），以實現與執行機構配套的閥門或其他裝置開度的精確定位，同時輸出4～20mADC的位置反饋信號。其核心控制部件電子式伺服控制器應用現代數字技術，對DCS/PLC規范設計而成，集信號采集、處理、反饋、控制于一體。采用*的電子制動電路并附加機械阻尼裝置消除慣性，可瞬時停機，定位時無振蕩，定位精度可達0.3%以上。可控硅輸出，動作時間快，輸出穩定，可靠性高。體積小，輕便宜人，性能可靠，配套簡單，流通能力大，特別適合于介質是粘稠，含顆粒，纖維性質的場合。目前該閥廣泛應用于食品，環保，輕工，石油，造紙，化工，教學和科研設備，電力等行業的工業控制系數。

HRVO electric cut off valve O-receiving computer or directly to the output of industrial instruments such as 4 ~ 20mADC or 1 ~ 5VDC control signal, 220VAC power supply, according to the valve position feedback signal and setpoint deviation of the actuator drive more inligent step motors adjustment （PID regulation） to achieve with the valve actuator or other device supporting the opening of the precise positioning, while the output 4 ~ 20mADC position feedback signal. The core components of electronic servo controller control the application of modern digital technology, the DCS / PLC specification designed, set of signal acquisition, processing, feedback control in one. The use of original electronic braking circuit and additional mechanical damping device eliminates inertia, can be instantaneous stop, positioning without vibration, positioning accuracy of up to 0.3% or more. SCR output, fast time, output stability, high reliability. Small size, light and pleasant, reliable performance, supporting a simple, flow capacity, especially suitable for medium is viscous, containing particles, fiber nature of the occasion. The valve is now widely used in food, environmental protection, light industry, petroleum, paper, chemicals, teaching and research equipment, industrial control power factor and other industries.
