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

The device is controlled via a 120 cm long, supplied two-wire cable that connects directly to the motor. This cable can be connected to any relay or other potential-free switch. A closed switch closes the valve, an open switch opens the valve. Potential-free switching contacts are available in most smart home systems (Shelly, Z-Wave, SmartThings, Bosch, Homematic, etc.) or alarm systems. If a switching contact cannot be installed near the shut-off valve, the two-wire cable can be extended wirelessly. The corresponding product is KFRDRY02.

The motor is powered by a 12V mains supply and is completely water and dirt protected up to the power supply unit. A battery pack is available as an option for independent operation.

Various adapter rings and a sophisticated connection system enable the motor to be used on all modern angle seat valves from DN15 to DN32.
