Motor Servo for Angled Seat Valves for WiFi
SKU: KFRWIE01
Version: 1.0.0

↑1. Product Description
The motor drive for angle seat valves (KFR valves) allows retrofitting of existing and
already installed shut-off valves into radio-controlled intelligent devices without
interrupting the water supply or cutting into the water pipe. The motor is powered by a
12V power supply and is completely water- and dirt-protected up to the power supply.
Various adapter rings and a sophisticated connection system enable the motor's use on
all modern angle seat valves from DN15 to DN32. Thanks to an additional water sensor that
plugs directly into the device, the motor can be used for leakage protection without
further configuration.
The servo motor is water-protected and can be used in damp, dirty, and outdoor
environments. In the open state, the motor automatically performs valve maintenance once a
week (closing/opening by 1/8 turn to remove dirt and lime). A wired leakage sensor can be
connected directly to the device. If water is detected, the valve shuts off.
The device is controlled via Wi-Fi, with several options available:
- Conveniently via the Aqua-Scope app
- Via the IoT protocol MQTT. A third-party MQTT broker is required for this. More information can be found in the developer manual.
- Via direct integration into a smart home system using so-called JSON webhooks. More information can be found in the developer manual.
