Retrofit motor for angle seat/KFR valve (LoRaWAN)

SKU: KFRLWE01
Version: 1.6

1. Product Description

The motor drive for angle seat valves (KFR valves) enables the retrofitting of existing and already installed shut-off valves into remotely controllable smart devices, without interrupting the water supply or cutting into the water pipe.

The device supports the LoRaWAN wireless protocol and can be integrated into an existing LoRaWAN network as a Class C device. This requires LoRaWAN network coverage and that the device keys be registered with the LoRaWAN provider’s JOIN server. If no LoRaWAN connection is available, the device will automatically accept control commands from Aqua-Scope sensors after about 20 seconds. Details can be found in the section 'Communication with a LoRaWAN Network'.

The motor is powered by a 12V power supply and is fully water- and dirt-resistant up to the power supply unit. An optional battery pack is available for off-grid operation.

Various adapter rings and a sophisticated connection system allow the motor to be used with all modern angle seat valves from DN15 to DN32. Thanks to an additional water sensor that can be plugged directly into the device, the motor can also be used for leakage protection without any wireless connection at all.
