The Energy Valve is a pressure independent valve that measures and manages coil energy by using an embedded electromagnetic or ultrasonic flow meter, along with supply and return water temperature sensors. Patented Power Control and Belimo Delta T Manager™ logics built-in monitors coil performance and optimizes the available energy of the coil by maintaining the Delta T. In addition to the standard analog signal and feedback wiring, it communicates its data to the Building Management System via BACnet MS/TP or BACnet IP.
The built-in web server collects up to 13 months of data that can be downloaded to external tools for further optimization.
Some of these features contribute to LEED points.

Download Installation Instructions


INLET LENGTH

The Energy Valve requires at least 5 x pipe diameter length on the valve inlet to guarantee sensor accuracy.



½” [DN15] 5 x nominal pipe size = 2.5” [64 mm]
¾” [DN20] 5 x nominal pipe size = 3.75” [95 mm]
1” [DN25] 5 x nominal pipe size = 5” [127 mm]
1¼” [DN32] 5 x nominal pipe size = 6.25” [159 mm]
1½” [DN40] 5 x nominal pipe size = 7.5” [191 mm]
2” [DN50] 5 x nominal pipe size = 10” [254 mm]

NOTE

No requirements for outlet length. Elbows can be installed directly after the valve.

PIPING

Recommended to be installed on the return side of the coil.
For ½” through 2” valves both temperature sensors are remote and are supplied with female NPT threaded pipe body. The (T2) sensor should be installed in the direction of flow after the actuator. The (T1) sensor should be installed on the other side of the coil. P/T ports are recommended on either side of the valve and the supply side of heat transfer device to allow for pressure, flow measurement, and calculation.

Belimo recommends installing one strainer per system. If the system has multiple branches, it is recommended to install one strainer per branch.

2½” [DN65] 5 x nominal pipe size = 12.5” [317 mm]
3” [DN80] 5 x nominal pipe size = 15” [381 mm]
4” [DN100] 5 x nominal pipe size = 20” [508 mm]
5” [DN125] 5 x nominal pipe size = 25” [635 mm]
6” [DN150] 5 x nominal pipe size = 30” [762 mm]

NOTE

No requirements for outlet length.
Elbows can be installed directly after the valve.

2½” - 6” VALVE SIZES



The remote temperature sensor should be installed on the opposite pipe entering the coil from where the Energy Valve is installed. A 1/2” NPT female union should be welded on the pipe to allow the installation of the thermo well. The Energy Valve is equipped with a 32 ft. (10m) cable for the remote sensor. If a shorter remote sensor cable is required, the cable is also available in the following sizes: 4.9 ft (1.5m), 9.8 ft. (3m) or 16.4 ft (5m).
Please order the appropriate size for the application.



REMOTE WELL INSTALLATION DIMENSIONAL PARAMETERS

ORIENTATION



The Energy Valves valve assembly can be installed in a vertical or horizontal arrangement,
as long as the actuator is positioned to avoid condensation from dripping onto the actuator.

PIPING

The Energy Valve is recommended to be installed on the return side of the coil. This diagram is for typical applications only. Consult engineering specifi cation and drawings for particular circumstances. Install provided thermal well on the other side of the coil (T1). P/T ports are recommended on either side of the valve and the supply side of the heat transfer device to allow for pressure/fl ow measurement/ calculation.





It is not necessary to install one strainer per unit. Belimo recommends installing one strainer per system. If the system has multiple branches, it is
recommended to install one strainer per branch. The Energy Valve cannot be piped in a parallel orientation.

Product Description

The device is an electronic pressure independent characterized control valve (CCV) with adjustable flow rate, sensor-operated flow control and monitoring of power and energy. The set-point, configuration parameters and feedback values are communicated via BACnet/IP or BACnet MS/TP. The commissioning of the device (BACnet Device Address, IP Address settings, Foreign Device settings, MS/TP) is done via the integrated web-server.
