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. This valve is designed to fit in compact areas where on/off, floating point and modulating control is required using 24 VAC.Suitable Actuators Non-SpringSpringB225HT464LRLFDimensions (Inches [mm])DEBAFCH2H1LRB, LRXABCDEFH1H28.6” [218]5.14” [131]6.89” [175]6.36” [162]1.3” [33]1.18” [30]0.5” [15]B225HT464, 1”, High Temperature CCVStainless Steel Ball and Stem800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 09/20/2016 - Subject to change. © Belimo Aircontrols (USA), Inc.Dimensions (Inches [mm])EFBADCLFABCDEF9.47” [241]5.14” [131]7.76” [197]6.84” [174]1.89” [48]B225HT464, 1”, High Temperature CCVStainless Steel Ball and Stem800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 09/20/2016 - Subject to change. © Belimo Aircontrols (USA), Inc.Technical Data2253Power Supply24 VAC ± 20%, 50/60 Hz, 24 VDC ± 10%Power Consumption Running1.5 W Power Consumption Holding0.2 W Transformer Sizing2.5 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, IP54, 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.LRB24-3On/Off, Floating Point, Non-Spring Return, 24 V800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 02/16/2017 - 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.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 Transformer1Floating Point - Triac Source 218Blk (1) CommonRed (2) + HotWht (3) Y InputLineVolts24 VAC TransformerComHot61Floating Point - Triac SinkLRB24-3On/Off, Floating Point, Non-Spring Return, 24 V800-543-9038 USA866-805-7089 CANADA203-791-8396 LATIN AMERICA / CARIBBEANDate created, 02/16/2017 - Subject to change. © Belimo Aircontrols (USA), Inc.Next >
