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 Data2292Power Supply24 VAC ± 20%, 50/60 Hz, 24 VDC ± 10%Power Consumption Running2.5 WPower Consumption Holding1 WTransformer Sizing5 VA (class 2 power source)Electrical Connection3ft [1m], 18 GA plenum cable with 1/2” conduit connectorOverload Protectionelectronic throughout 0° to 95° 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 mAFeedback Output U2 to 10 VDC (max 0.7 mA) for 95°Angle of Rotation90°Direction of Rotation (Motor)reversible with built-in switchDirection of Rotation (Fail-Safe)reversible with CW/CCW mountingPosition Indicationvisual indicator, 0° to 95° (0° is full spring return position)Running Time (Motor)150 sec constant, independent of loadRunning Time (Fail-Safe)<25 sec @ -4°F to 122°F [-20°C to 50°C], < 60 sec @ -22°F [-30°C]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, IP54Agency Listings†cULus acc.

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.
