Retrofit motor for angle seat/KFR valve (Wi-Fi)

Motor drive for angle seat valves (KFR valves) – intelligent leakage protection against water damage

The motorized actuator for angle seat valves and KFR valves is the ideal solution for automatically shutting off the water supply in the event of a leak or pipe break. It allows for easy retrofitting of existing shut-off valves and reliably protects buildings from water damage – all without any intervention in the water pipe.

Product benefits at a glance:

• Retrofittable motor drive for angle seat valve / KFR valve

• Effective leakage protection to prevent damage

• No interruption of the water supply during assembly

• No cutting or opening of the water pipe is necessary.

• Compatible with valves from DN15 to DN32

• Suitable for indoor, damp and outdoor use.

• Ideal for houses, apartments, basements, commercial spaces and utility rooms

Reliable protection against water damage and burst pipes

Water damage from burst pipes or leaking lines often goes unnoticed and causes high consequential costs. The motor drive can be directly connected to a wired leak sensor . If the sensor detects water, the angle seat valve closes automatically – without additional configuration or cloud connection.

This creates active leak protection that stops damage early and prevents costly repairs.

Robust servo motor for continuous use

The integrated servo motor is water and dirt resistant and is powered by a safe 12V power supply . This makes the motor drive suitable for demanding environments such as basements, utility rooms, or outdoor installations.

Automatic valve training ensures long-term reliability: When open, the motor moves the valve slightly once a week to prevent limescale and dirt deposits .

Universal compatibility & easy assembly

Thanks to various adapter rings and a well-designed mounting system, the motor drive is compatible with virtually all modern KFR valves and angle seat valves from DN15 to DN32 . Installation is quick, clean, and requires no special tools.

Ideal for smart automation & damage prevention

The motor drive is perfectly suited for automating water shut-off and is an effective solution for preventing damage from water leaks . Whether for a single-family home, rental property, or commercial building – the intelligent valve drive reliably protects against the consequences of an undetected leak.

The device is controlled via Wi-Fi, with several options available:

1. Conveniently via the Aqua-Scope app.
2. This uses the IoT protocol MQTT. A third-party MQTT broker is required. See the developer manual for more information.
3. Via direct connection to a smart home system using JSON webhooks. More information can be found in the developer manual.
