EV050+LRX-E • en-us • 2022-03-31 • Subject to change1 / 6 The Belimo Energy Valve consists of a characterized control valve, an actuator and a thermal energy meter with a logic and a sensor module. The logic module provides the power supply, the communication interface and the NFC connection of the energy meter. All relevant data are measured and recorded in the sensor module. This modular design of the energy meter means that the logic module can remain in the system if the sensor module is replaced.

Outdoor application: only possible in case that no (sea) water, snow, ice, insolation or aggressive gases interfere directly with the actuator and that is ensured that the ambient conditions remain at any time within the thresholds according to the data sheet. Only authorized specialists may carry out installation. All applicable legal or institutional installation regulations must be complied during installation. The device contains electrical and electronic components and must not be disposed of as household refuse. All locally valid regulations and requirements must be observed. The Energy Valve measures energy using its built-in electronic flow sensor and supply and return temperature sensors. Controls power with its power control logic providing linear heat transfer regardless of temperature and pressure variations. Manages low delta-T with its built in Delta-T manager. Measures glycol with advanced algorithms in its built in flow sensor. An IoT device utilising cloud-based technology to optimise performance. Water-side control of heating and cooling systems for AHUs and water coils. The Energy Valve is an energy metering pressure independent control valve that measures, documents and optimises water coil performance. The HVAC performance device is comprised of four components: characterized control valve (CCV), measuring pipe with volumetric flow sensor, temperature sensors and the actuator itself. The adjusted maximum flow (V'max) is assigned to the maximum control signal DDC (typically 10 V / 100%). Alternatively, the control signal DDC can be assigned to the valve opening angle or to the power required on the heat exchanger (see power control). The HVAC performance device can be controlled via communicative or analogue signals. The fluid is detected by the sensor in the measuring pipe and is applied as the flow value. The measured value is balanced with the setpoint. The actuator corrects the deviation by changing the valve position. The angle of rotation α varies according to the differential pressure through the control element (see flow rate curves). *All flow tolerances are at 68°F [20°C] & water.EV050+LRX-E • en-us • 2022-03-31 • Subject to change4 / 6 T-piece with thermowell DN 1/2" [15]A-22PE-A09 T-piece with thermowell DN 3/4" [20]A-22PE-A10 T-piece with thermowell DN 1" [25]A-22PE-A11 T-piece with thermowell DN 1 1/4" [32]A-22PE-A12 T-piece with thermowell DN 1 1/2" [40]A-22PE-A13 T-piece with thermowell DN 2" [50]A-22PE-A14 Converter Bluetooth / NFCZIP-BT-NFC Supply from isolating transformer. Parallel connection of other actuators possible. Observe the performance data. The wiring of the line for BACnet MS/TP / Modbus RTU is to be carried out in accordance with applicable RS485 regulations. Modbus / BACnet: Supply and communication are not galvanically isolated. Connect earth signal of the devices with one another. Sensor connection: An additional sensor can optionally be connected to the thermal energy meter. This can be a passive resistance sensor Pt1000, Ni1000, NTC10k (10k2), an active sensor with output DC 0...10 V or a switching contact. Thus the analogue signal of the sensor can be easily digitised with the thermal energy meter and transferred to the corresponding bus system. Analog output: An analog output is available on the thermal energy meter. This can be selected as DC 0...10 V, DC 0.5...10 V or DC 2...10 V. For example, the flow rate or the temperature of the temperature sensor T1 / T2 can be output as an analog value.

The ball valve may not be installed in a hanging position, i.e. with the spindle pointing downwards. Installation in the return is recommended. The water quality requirements specified in VDI 2035 must be adhered to. Belimo valves are regulating devices. For the valves to function correctly in the long term, they must be kept free from particle debris (e.g. welding beads during installation work). The installation of a suitable strainer is recommended.EV050+LRX-E • en-us • 2022-03-31 • Subject to change6 / 6 Ball valves, rotary actuators and sensors are maintenance-free. Before any service work on the final controlling device is carried out, it is essential to isolate the rotary actuator from the power supply (by unplugging the electrical cable if necessary). Any pumps in the part of the piping system concerned must also be switched off and the appropriate slide valves closed (allow all components to cool down first if necessary and always reduce the system pressure to ambient pressure level). The system must not be returned to service until the ball valve and the rotary actuator have been correctly reassembled in accordance with the instructions and the pipeline has been refilled by professionally trained personnel. The direction of flow, specified by an arrow on the housing, is to be complied with, since otherwise the flow rate will be measured incorrectly. Before installing the thermal energy meter, the circuit must be thoroughly rinsed to remove impurities. The energy meter must not be subjected to excessive stress caused by pipes or fittings. In order to achieve the specified measuring accuracy, a flow-calming section or inflow section in the direction of the flow is to be provided upstream from the flow sensor. Its dimensions should be at least 5x DN. 14.0" [356]8.8” [224]6.1" [154]5.4” [137]1.8" [46]1.8" [46]Next >
