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-SpringSpringB210BTR, LRTFR, LFDimensions (Inches [mm])DH2CBAEFH1LRB, LRXABCDEFH1H29.4” [239]2.38” [60]5.19” [132]4.61” [117]1.3” [33]1.18” [30]1.1” [28]B210B, 2-Way, Characterized Control ValveChrome Plated Brass Ball and Nickel Plated Brass Stem800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 06/30/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.Dimensions (Inches [mm])ABDCEFTRABCDEF3.72” [95]2.38” [60]4.79” [122]4.21” [107]1.25” [32]Dimensions (Inches [mm])BADCEFTFRB, TFRXABCDEF6.59” [167]2.38” [60]4.9” [124]4.32” [110]1.53” [38]Dimensions (Inches [mm])BADCEFLFABCDEF7.92” [201]2.38” [60]5.67” [144]5.09” [129]1.82” [46]B210B, 2-Way, Characterized Control ValveChrome Plated Brass Ball and Nickel Plated Brass Stem800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 06/30/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.Technical Data2495Power Supply24 VAC ± 20%, 50/60 Hz, 24 VDC ± 10%Power Consumption Running0.5 WTransformer Sizing1 VA (class 2 power source)Electrical Connection15ft [5m], 18 GA plenum rated cableOverload Protectionelectronic throughout full rotationOperating Range Y2 to 10 VDC, 4 to 20 mA w/ ZG-R01 (500 Ω, 1/4 W resistor)Input Impedance100 k Ω for 2 to 10 VDC (0.1 mA), 500 Ω for 4 to 20 mAAngle of Rotation90°Direction of Rotation (Motor)reversible with protected switchPosition Indicationintegrated into handleManual Overridepush down handleRunning 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 type 1 / IP40Agency 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)<35 dB (A) Servicingmaintenance freeQuality StandardISO 9001TR24-SR/500 USModulating, Non-Spring Return, 24 V, for 2 to 10 VDC or 4 to 20 mA800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 06/30/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.Wiring DiagramsINSTALLATION NOTESProvide overload protection and disconnect as required.Actuators may also be powered by 24 VDC.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.Actuators may be connected in parallel if not mechanically linked. Power consumption 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.
