The valve has been designed for use in stationary potable water systems and must not be used outside the specified field of application, especially in aircraft or in any other airborne means of transport.Technical data sheetEXT-LD14104BE1AX www.belimo.usEXT-LD14104BE1AX • en-us • 2021-02-10 • Subject to change2 / 2 Mode of operation Recommended installation positions Product features The on/off ball valve is adjusted by a rotary actuator. The rotary actuator is connected by an on/off signal. Open the ball valve counterclockwise and close it clockwise. Installation notes The ball valve can be installed upright to horizontal. The ball valve may not be installed in a hanging position, i.e. with the stem pointing downwards.Technical data sheetDKRX24-3-T N4 www.belimo.usDKRX24-3-T N4 • en-us • 2021-01-29 • Subject to change1 / 2 On/Off, Floating Point, Electronic Fail-Safe, 24 V Technical data Electrical dataNominal voltageAC 24 V Nominal voltage frequency50/60 Hz Power consumption in operation12 W Power consumption in rest position3 W Transformer sizing21 VA (class 2 power source) Electrical ConnectionTerminal blocks Overload Protectionelectronic thoughout 0...90° rotation Functional data Direction of motion motorselectable with switch 0/1 Manual overrideunder cover Running Time (Motor)default 150 s, variable 90...150 s Running time motor variable90...150 s Running time fail-safe<35 s Noise level, motor45 dB(A) Noise level, fail-safe60 dB(A) Position indicationMechanically, 5...20 mm stroke Safety data Degree of protection IEC/ENIP66/67 Degree of protection NEMA/ULNEMA 4X UL Enclosure Type 4X Quality StandardISO 9001 Ambient temperature-22...122°F [-30...50°C] Storage temperature-40...176°F [-40...80°C] Ambient humiditymax. 95% r.H., non-condensing Servicingmaintenance-free Weight Weight3.2 lb [1.5 kg] Materials Housing materialPolycarbonate Electrical installation INSTALLATION NOTES Provide overload protection and disconnect as required. For triac sink the Common connection from the actuator must be connected to the Hot connection of the controller. Position feedback cannot be used with a triac sink controller; the actuator internal common reference is not compatible. Actuators may be connected in parallel if not mechanically linked. Power consumption and input impedance must be observed. IN4004 or IN4007 diode. (IN4007 supplied, Belimo part number 40155). Actuators are provided with a numbered screw terminal strip instead of a cable. Meets cULus requirements without the need of an electrical ground connection. Warning!
