E-POWER IP PROPERTIES
Thank you for purchasing a CLA-VAL turbine. With appropriate care, this CLA-VAL e-Power IP will provide power for your
valve for many years. The CLA-VAL e-Power IP is built with the latest technology together with very high quality
components.
The CLA-VAL e-Power IP is an electrical generator using available hydraulic energy directly from the water distribution
network. The e-Power IP is typically installed into the bypass of the CLA-VAL valve.
The e-Power IP powers various devices located within close proximity of the valve or on the valve itself, e.g. motorized
pilots, sensors, telemetry, PLC or HMI interfaces.
2.1 PERFORMANCE
At the optimum operating point of the turbine, (differential Pressure (DP) = 6 mhd and Flow (Q) = 50 l/min).The
rechargeable battery delivers the following output voltage, current and power:

The electrical power produced by the e-Power IP charges the battery. The power (W) to charge the battery is the
multiplication of the current (A) and voltage (V). The efficiency between the power supplied by the battery and the power
generated by the turbine is 88%.
Note:
The power supplied in the graph above is achieved by optimizing the power supplied by the turbine for each differential pressure.

Note:
Example: For an FM mounting with a body tapping 1" and a bypass pipe 1": 3 m + 6 mhd = total of
9 mhd differential pressure (inlet - outlet of the
valve)
to generate 16 W of power by the turbine.
