Product Overview

The CLA-VAL e-Power IP: Power from Flowing Water is an electrical generator system that autonomously harnesses available hydraulic energy directly from the water distribution network. It combines an electrical generator, a solenoid bypass shut-off, and a hydraulic differential pressure controller. The system is installed into the bypass of a CLA-VAL valve. The electrical box contains a 12V rechargeable lead-acid battery and an electronic charge management system, supplying continuous 14 Watt power at a differential pressure of 6 mhd and flow of 50 l/min. The e-Power IP generates 16 Watt to recharge the battery using the pressure drop across the valve. The efficiency between the power supplied by the battery and the generated power by the turbine is 88%. This system provides 12V and 24V output to power various devices located near or on the valve, such as motorized pilots, sensors, telemetry, PLCs, or HMI interfaces. The e-Power IP's innovative and patented design ensures compact management of differential pressure and energy production.

Installation & Maintenance

• The e-Power IP is installed into the bypass of the CLA-VAL valve, typically a 1" pipe.
• Maintenance is easy, with the battery being totally maintenance-free.
• Electrical box assembly contains the PCB and rechargeable battery; user wires only 12V and/or 24V output.
• Various assembly configurations are available: Factory Mounted (FM) with rigid piping, Field Retrofit (RM) with mounting kit, piping and fittings (for easy on-site assembly), and Wall Mounted (WM) for use on any hydraulic valve or fitting with minimum differential pressure and flow conditions.
• Minimum site operation and effort ensure very easy installation.
• The charging cycle starts when the battery reaches 12.0 V and stops at 13.6 V, with an additional charging mode at 13.0 V for full charge.
• For low water consumption systems, a DPC device (optional AQUA 80-451 pressure reducer) may be required to prevent downstream overpressure.
