Some other common applications include Unit Ventilators, VAV box re-heat coils and bypass loops. This valve is suitable for use in a hydronic system with variable or constant flow.Suitable Actuators Non-SpringSpringB329ARB(X)AFB(X)Dimensions (Inches [mm])H1EFBACDH2ARB, ARXABCDEFH1H210” [254]3.96” [101]6.76” [172]5.51” [140]1.73” [44]2.14” [54]0.75” [20]0.5” [15]B329, 3-Way, Characterized Control ValveStainless Steel Ball and Stem800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 11/06/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.Dimensions (Inches [mm])B ACDEFARB N4, ARX N4, NRB N4, NRX N4ABCDEF11.36” [289]3.96” [101]8.8” [224]7.55” [192]3.15” [80]Dimensions (Inches [mm])EFH1DBACH2ARQB, ARQXABCDEFH1H29.69” [246]3.96” [101]7.45” [190]6.2” [158]1.73” [44]2.14” [54]1.39” [34]0.75” [20]Dimensions (Inches [mm])DBACEFAFRB, AFRXABCDEF10.57” [269]3.96” [101]6.9” [175]5.65” [144]2.14” [54]1.26” [32]B329, 3-Way, Characterized Control ValveStainless Steel Ball and Stem800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 11/06/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.Technical Data100175Power Supply24 VAC, ±20%, 50/60 Hz, 24 VDC, ±10%Power Consumption Running15 WPower Consumption Holding1.5 WTransformer Sizing26 VA (class 2 power source)Electrical Connection3ft [1m], 18 GA plenum cable with 1/2” conduit connectorOverload Protectionelectronic thoughout 0° to 90° rotationOperating Range Y2 to 10 VDC, 4 to 20 mA w/ ZG-R01 (500 Ω, 1/4 W resistor), variable (VDC, on/off)Input Impedance100 k Ω for 2 to 10 VDC (0.1 mA), 500 Ω for 4 to 20 mA, 1500 Ω for On/OffFeedback Output U2 to 10 VDC, 0.5 mA max, VDC variableAngle of Rotation90°Direction of Rotation (Motor)reversible with built-in switchPosition Indicationintegrated into handleManual Overrideexternal push buttonRunning Time (Motor)10 secAmbient Temperature Range-22°F to 122°F [-30°C to 50°C]Storage Temperature Range-40°F to 176°F [-40°C to 80°C]HousingNEMA 2, IP54Agency Listings†cULus acc. to UL60730-1A/-2-14, CAN/CSA E60730-1:02, CE acc. to 2004/108/EC and 2006/95/ECNoise Level (Motor)max. 52 dB (A) Servicingmaintenance freeQuality StandardISO 9001†Rated Impulse Voltage 800V, Type action 1, Control Pollution Degree 3.ARQX24-MFTModulating, Non-Spring Return, 24 V, Multi-Function Technology®800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 11/30/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.Wiring DiagramsINSTALLATION NOTESProvide overload protection and disconnect as required.Actuators may be connected in parallel. Power consumption and input impedance must be observed.Actuators may also be powered by 24 VDC.Only connect common to negative (-) leg of control circuits.A 500 Ω resistor (ZG-R01) converts the 4 to 20 mA control signal to 2 to 10 VDC.IN4004 or IN4007 diode. (IN4007 supplied, Belimo part number 40155).Actuators with plenum cable do not have numbers; use color codes instead.Meets cULus requirements without the need of an electrical ground connection.!WARNING! LIVE ELECTRICAL COMPONENTS!During installation, testing, servicing and troubleshooting of this product, it may be necessary to work with live electrical components. Have a qualified licensed electrician or other individual who has been properly trained in handling live electrical components perform these tasks. Failure to follow all electrical safety precautions when exposed to live electrical components could result in death or serious injury.
