Electro pneumatic positioner Electro pneumatic positioner ep3000 , mounted on pneumatic actuator, moves the actuator by receiving dc 4~20ma signals from a controller. Also, the function of detecting and returning the actuator displacement provides accurate positioning in response to dc 4~20ma signals

HIC series smart valve positioner contains several kinds of specifications such as HIC11, HIC12, HIC08.It uses two-wire system transmission (The power source 4í½20mA simulating signal simultaneously transmits on two lines ). The psitioner and the actuator constitute a close loop control circuit. In this control circuit, the valve position feedback single as an variable which compared with rated signal in microprocessor and the D-value between them sends out different length of pulse through the delivery outlet of the main control panel to control the output pressure of the I/P change unit, thereby the positioner drive the control valve to act. (Refer to Fig.1) The pneumatic control valve with HIC smart valve positioner can overcome the friction force and unbalanced force of the valve plug well and enhance reaction speed of the control valve to rapid and precision localization, especially for vibration frequent places. It can replace conventional explosion-proof current-to-pneumatic valve positioner. The purchaser can monitor the valve position information through the feedback current and regulate or set the controlling parameter of the positioner with axial magnet or upper monitor at any moment. The purchasers only need to reset the relative parameter of the valve positioner and avoid changing the control valve because of the control system variation, so it is widely used in automatic control system such as petroleum, chemical industrial, electric power, metallurgy and light industrial, etc. TECHNICAL PARAMETER í± Input signalú¦4í½20mA analog signals í± Input loading voltageú¦7Víó9Vú¿With communicationú¬ í± Air supply pressureú¦0.16MPaí½0.6MPa í± intrinsic errorú¦í+1.0% í± Hysteresisú¦1.0% í± Dead bandú¦0.1%ú¿Min.ú¬ í± Functionú¦Self-diagnostics, configuration, travel characteristic correction, HART communication and so on í± Air consumptionú¦í_4.0Nl/min í± Strokeú¦10í½100mmú¿Turn angle 60ípí½90ípú¬ í± Conditions of working atmosphereú¦ a.Ambient temperatureú¦-40í½+80ípCú¼Explosion ¿Cproof typeú¦-40í½+60ípC b.Ambient humidityú¦5%í½95%ú+ c.Ambient atmosphereú¦86í½106kPaú+ d.There is no corrosive gas in ambient air. í± Power supplyú¦24V.DC í± Explosive-proof signú¦Ex dIICT6íóEx iaIICT6 í± Explosive-proof gradeú¦Factory Explosive-proof í± Enclosure classificationú¦IP65.
