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-SpringSpringB352ARB(X)AFB(X)Dimensions (Inches [mm])H1EFBACDH2ARB, ARXABCDEFH110.5” [267]4.90” [124.5]7.73” [196]5.98” [152]1.73” [44]2.6” [66]0.75” [20]B352, 3-Way, Characterized Control ValveStainless Steel Ball and Stem800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 01/26/2018 - Subject to change. © Belimo Aircontrols (USA), Inc.Dimensions (Inches [mm]) DCBAEFNRB N4, NRX N4ABCDEF11.36” [289]4.90” [124.5]9.76” [248]8.01” [203]3.15” [80]Dimensions (Inches [mm])EFH1DBACH2ARQB, ARQXABCDEFH1H29.9” [251]4.90” [124.5]8.32” [211]6.57” [167]2.28” [58]2.6” [66]0.75” [20]0.5” [15]Dimensions (Inches [mm])DBACEFAFRB, AFRXABCDEF11.27” [286]4.90” [124.5]8.36” [212]6.61” [168]2.6” [66]B352, 3-Way, Characterized Control ValveStainless Steel Ball and Stem800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 01/26/2018 - Subject to change. © Belimo Aircontrols (USA), Inc.Technical Data64308Power Supply24 VAC ± 20%, 50/60 Hz, 24 VDC ± 10%Power Consumption Running7.5 WPower Consumption Holding3 WTransformer Sizing10 VA (class 2 power source)Electrical Connection3ft [1m], 18 GA appliance cable with 1/2” conduit connectorOverload Protectionelectronic throughout 0° to 95° rotationOperating Range Y0 to 135 Ω Honeywell Electronic Series 90, 0 to 135 Ω inputFeedback Output U2 to 10 VDC, 0.5 mA max, VDC variableAngle of Rotation90°Direction of Rotation (Motor)reversible with switchDirection of Rotation (Fail-Safe)reversible with CW/CCW mountingPosition Indicationvisual indicator, 0° to 95° (0° is full spring return position)Manual Override5 mm hex crank (3/16” Allen), suppliedRunning Time (Motor)150 sec (default), variable (70 to 220 sec)Running Time (Fail-Safe)<20 secAngle of Rotation Adaptationoff (default)Ambient 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, IP54, UL enclosure type 2Agency 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)<45 dB (A) Noise Level (Fail-Safe)<62 dB (A) Servicingmaintenance freeQuality StandardISO 9001†Rated Impulse Voltage 800V, Type of action 1.AA, Control Pollution Degree 3AFRX24-MFT95Modulating, Spring Return, 24 V, 0 to 135 Ω Input800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 08/14/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.Wiring DiagramsINSTALLATION NOTESProvide overload protection and disconnect as required.Actuators may also be powered by 24 VDC.22Actuators and controller must have separate transformers.23Consult controller instruction data for more detailed information.24Resistor value depends on the type of controller and the number of actuators. No resistor is used for one actuator. Honeywell® resistor kits may also be used.25To reverse control rotation, use the reversing switch.46Actuators may be controlled in parallel. Current draw and input impedance must be observed.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.
