Product Description APV400 Intelligent Valve Positioner operates on the principle of piezoelectric valves and is equipped with HART communication protocol. It effectively converts a 2-wire 4 to 20 mA control signal into pneumatic output for the actuator, making it suitable for both pneumatic linear actuators and rotary actuators. This functionality enables precise positioning of the valve according to predetermined settings. The positioner features a compact and modular design that offers high cost-effectiveness. Its self-tuning capability for control parameters, combined with excellent adaptability, significantly reduces setup time while ensur ing optimal control performance.Features· Adaptive predictive control algorithm for faster response and more precise control.· Automatic detection of valve lower and upper limits, opti mizing valve control parameters to enhance accuracy.· Dot matrix LCD display with multi-language support, ro tatable by 180° for easy observation. Equipped with four configuration buttons for local valve control and settings adjustments.· Supporting parameter configuration for split range, characteristic curves, stroke range and direction, tight closure, dead zone, control parameters, digital input, alarm and fault outputs, and more.· Diagnostic capabilities include leakage detection, partial stroke testing, upper and lower limit monitoring, pressure and temperature diagnostics, stroke accumulation, directional change counts, and piezoelectric operation monitoring.· IDM software allows setup and calibration of valve accessories, with status monitoring and alarm tracking.· Compatible with HART 5 and HART 7 communica tion protocols.· Including one isolated digital input and two dry con tact inputs.· Digital output with electric isolation provides alarm or fault notifications.· Electrically isolated position feedback block outputs 4 to 20mA position feedback.· Optional "faillast" function ensures operational stability during power, gas, or signal failure.· Equipped with surge protection for enhanced reliability.Main Parameters· Main Parameters· Type: Piezoelectric· Signal: Two-wire 4 to 20 mA DC input, optional HART 5 and HART 7, 4 to 20 mA feedback output· Protection Grade: IP66· Explosion-proof: Exia IIC T4 … T6 Ga, Exdb IIC T4 … T6 Gb· Three-break Fail Last: Optional valve manifolds can make valve fail last in case of power failure, gas failure, and signal failure· Surge: Surge protection function· Diagnostic Function: Leakage detection, partial stroke test, upper limit and lower limit monitoring, pressure detection diagnos tic, temperature diagnostic, stroke accumulation, direction change times, piezoelectric operation times, etc.Model CodeModel TypeCodeDescriptionAPV400Stroke typeLLinearRRotaryAction typeSSingle actingDDouble actingExplosion protectionnNon-explosion (IP66)iIntrinsically safe (Exi)dFlameproof (Exd)tDust ignition-proof (Ext)kIntrinsically safe (Exi), dust ignition-proof (Ext)eFlameproof (Exd), dust ignition-proof (Ext)Feedback lever 110 to 30 mm240 to 130 mmXUser-defined80 to 90°Feedback module0None1Position feedback 4 to 20 mA2Limit switch3Position feedback 4 to 20 mA + limit switchCommunication function0NoneHHARTElectrical connectionMM20 × 1.5 femaleN1/2 NPT femaleAir supply connection11/4 NPT femaleFail position RFail safeHFail last (selected if three-break fail last is required)GFail openAmbient TemperatureT-30 to 80oCL-40 to 80oCHousing materialADie-cast aluminum type A (for intrinsically safe, normal type)BDie-cast aluminum type B (for Exd)CStainless steel type C (for intrinsically safe, normal type)DStainless steel type D (for Exd)Pressure gauge 0None1Stainless steel pressure gaugeMounting bracket0None1With rotary stroke mounting bracket (assembled to actuator 30 × 80 × 42)2With linear stroke mounting bracket (assembled to actuator 30 × 130 × 52)XCustomized bracketOptions0NoneASplit-range controlBAlarm module/digital I/O module (DIO)CPressure measurement moduleCertificationsNEPSINEPSI intrinsically safe Ex ia IIC T4 … T6 Ga Applicable standard: GB/T 3836.1-2021, GB/T 3836.4-2021NEPSI explosive-proof Ex db IIC T4 … T6 GbApplicable standard: GB/T 3836.1-2021, GB/T 3836.2-2021, GB/T 3836.31-2021NEPSI dust explosion prevention Ex tb IIIC T85oC … T135oC DbApplicable standard: GB/T 3836.1-2021, GB/T 3836.2-2021, GB/T 3836.31-2021CCCChina Compulsory Product Certification, NEPSI Ex ia IIC T4 … T6 Ga/Ex db IIC T4…T6 Gb/ Ex tb IIIC T85oC …T135oC DbOthersIndustrial automation instrument intelligent evaluation certificateApplicable standard: T/SHIIA000001-2020 Product ImagesPackaging & DeliveryCategoryProduct Size Gross WeightInternational Commercial Terms (Incoterms)Terms of PaymentNearest PortAPV400 Valve Positioner208 mm × 98 mm × 104 mm (excluding drive shaft attachment, blocking parts, manometer module)About 2.0 kgCIF, CFR, DAPLC, T/T, D/PShanghai, Guangzhou,TianjinRelated ProductsA100 Globe Control ValveA400 Ball ValveA700Butterfly ValveCompany Profile
