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-SpringSpringB209TR, LR, NRTFR, 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]B209, 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])ABDCEFTRABCDEF3.72” [95]2.38” [60]4.79” [122]4.21” [107]1.25” [32]Dimensions (Inches [mm]) DCBAEFNRB N4, NRX N4ABCDEF11.36” [289]2.38” [60]7.68” [195]7.06” [179]3.15” [80]Dimensions (Inches [mm])BADCEFTFRB, TFRXABCDEF6.59” [167]2.38” [60]4.9” [124]4.32” [110]1.53” [38]Dimensions (Inches [mm])BADCEFLFABCDEF7.9” [201]2.38” [60]5.67” [144]5.09” [129]1.82” [46]B209, 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 Data2458Power Supply24 VAC, ±20%, 50/60 Hz, 24 VDC, ±10%Power Consumption Running2.5 WPower Consumption Holding1.2 WTransformer Sizing5 VA (class 2 power source)Electrical Connection18 GA plenum rated cable with 1/2” conduit connector protected NEMA 2 (IP54) 3ft [1m] 10ft [3m] and 16ft [5m]Overload Protectionelectronic thoughout 0° to 90° rotationOperating Range Y0 to 135 Ω Honeywell Electronic Series 90, 0 to 135 Ω inputInput Impedance100 k ΩFeedback 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)150 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, IP42, UL Enclosure Type 2Agency Listings†cULus acc. to UL60730-1A/-2-14, CAN/CSA E60730-1:02, CE acc. to 2004/108/ECNoise Level (Motor)<35 dB (A) Servicingmaintenance freeQuality StandardISO 9001†Rated Impulse Voltage 800V, Type action 1.B , Control Pollution Degree 3.LRX24-MFT95Modulating, Non-Spring Return, 24 V, 0 to 135 Ω Input800-543-9038 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 with plenum cable do not have numbers; use color codes instead.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.
