HRVO電動(dòng)O形切斷球閥可直接接收計(jì)算機(jī)或工業(yè)儀表等輸出的4～20mADC或1～5VDC控制信號(hào)，220VAC電源,根據(jù)閥位反饋信號(hào)與設(shè)定值比較偏差對(duì)執(zhí)行機(jī)構(gòu)驅(qū)動(dòng)電機(jī)進(jìn)行智能步距調(diào)整（PID調(diào)節(jié)），以實(shí)現(xiàn)與執(zhí)行機(jī)構(gòu)配套的閥門(mén)或其他裝置開(kāi)度的精確定位，同時(shí)輸出4～20mADC的位置反饋信號(hào)。其核心控制部件電子式伺服控制器應(yīng)用現(xiàn)代數(shù)字技術(shù)，對(duì)DCS/PLC規(guī)范設(shè)計(jì)而成，集信號(hào)采集、處理、反饋、控制于一體。采用*的電子制動(dòng)電路并附加機(jī)械阻尼裝置消除慣性，可瞬時(shí)停機(jī)，定位時(shí)無(wú)振蕩，定位精度可達(dá)0.3%以上?？煽毓栎敵?，動(dòng)作時(shí)間快，輸出穩(wěn)定，可靠性高。體積小，輕便宜人，性能可靠，配套簡(jiǎn)單，流通能力大，特別適合于介質(zhì)是粘稠，含顆粒，纖維性質(zhì)的場(chǎng)合。目前該閥廣泛應(yīng)用于食品，環(huán)保，輕工，石油，造紙，化工，教學(xué)和科研設(shè)備，電力等行業(yè)的工業(yè)控制系數(shù)。

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.
