Retrofittable motor for angle seat/KFR valve (remote control via contact controller)

The motor drive for angle seat valves (KFR valves) allows existing and already installed shut-off valves to be retrofitted into remotely controlled, intelligent devices without interrupting the water supply or even cutting into the water pipe. The motor is powered by a 12V power supply. Various adapter rings and a sophisticated connection system enable the motor to be used with all modern angle seat valves from DN15 to DN32.

The servo motor is completely waterproof and dirt-resistant up to the power supply unit and can be used in damp, dirty, and outdoor environments. When open, the motor automatically performs a valve training cycle once a week (opening and closing by 1/8 of a turn to remove dirt and limescale).

The device is controlled by a remote interface unit (single unit DRYLWE02) using a robust LoRa radio link. The interface unit, in turn, is controlled by a potential-free switching contact and has a status contact that reports the current switching state of the valve. A closed contact closes the valve, an open contact opens the valve. Potential-free switching contacts are found in most smart home systems (Shelly, Z-Wave, SmartThings, Bosch, Homematic, etc.) or alarm systems.
