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 flow.Suitable Actuators Non-SpringSpringB265ARB(X)AFRB(X)Dimensions (Inches [mm])BACDH2EFH1ARB, ARXABCDEFH110.1” [257]5.55” [141]7.98” [202]5.98” [152]2.78” [71]1.88” [48]B265, 2-Way, Characterized Control ValveStainless Steel Ball and Stem800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 10/27/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.Dimensions (Inches [mm])BACDEFAFRB, AFRXABCDEF11.52” [293]5.55” [141]8.61” [220]6.61” [168]2.02” [51]Dimensions (Inches [mm])B ACDEFARB N4, ARX N4, NRB N4, NRX N4ABCDEF11.36” [289]5.55” [141]10.74” [274]8.01” [204]3.15” [80]Dimensions (Inches [mm])BACDH2EFH1ARQB, ARQXABCDEFH1H29.9” [251]4.21” [107]8.11” [195]6.11” [155]2.28” [58]0.75” [20]0.5” [15]Dimensions (Inches [mm])B ACDEFAFRB N4, AFRX N4ABCDEF12.98” [330]5.55” [141]10.29” [261]9.24” [235]3.39” [86]B265, 2-Way, Characterized Control ValveStainless Steel Ball and Stem800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 10/27/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.Technical Data2511Power Supply24 VAC, ±20%, 50/60 Hz, 24 VDC, ±10%Power Consumption Running2.5 WPower Consumption Holding0.5 WTransformer Sizing5.5 VA (class 2 power source)Electrical Connection3ft [1m], 18 GA plenum cable with 1/2” conduit connectorOverload Protectionelectronic thoughout 0° to 90° rotationInput Impedance600 ΩAngle of Rotation90°Direction of Rotation (Motor)reversible with built-in switchPosition Indicationintegrated into handleManual Overrideexternal push buttonRunning Time (Motor)90 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)<45 dB (A) Servicingmaintenance freeQuality StandardISO 9001Auxiliary switch1 x SPDT, 3A resistive (0.5A inductive) @ 250 VAC, adjustable 0 to 100%†Rated Impulse Voltage 800V, Type action 1.B , Control Pollution Degree 3.ARB24-3-SOn/Off, Floating Point, Non-Spring Return, 24 V800-543-9038 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.Actuators Hot wire must be connected to the control board common. Only connect common to neg. (-) leg of control circuits. Terminal models (-T) have no-feedback.Actuators with plenum cable do not have numbers; use color codes instead.44One built-in auxiliary switch (1x SPDT), for end position indication, interlock control, fan startup, etc.Apply only AC line voltage or only UL-Class 2 voltage to the terminals of auxiliary switches. Mixed or combined operation of line voltage/safety extra low voltage is not allowed.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. 231824 VAC TransformerBlk (1) CommonRed (2) + HotWht (3) Y InputLineVolts1On/Off 231824 VAC TransformerBlk (1) CommonRed (2) + HotWht (3) Y InputLineVolts1Floating Point ComHot2318Blk (1) CommonRed (2) + HotWht (3) Y InputLineVolts24 VAC Transformer1 218Blk (1) CommonRed (2) + HotWht (3) Y InputLineVolts24 VAC TransformerComHot61Floating Point - Triac Sink S1S2S3NCNO0° to 95°144Auxiliary SwitchesARB24-3-SOn/Off, Floating Point, Non-Spring Return, 24 V800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 11/30/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.Next >
