Retrofittable motor for ball valve (remote control via contact controller)

This motor upgrades existing and installed ball valves into intelligent water control devices. Thanks to its innovative clamping mechanism, it can be installed and removed within minutes on shut-off valves with a pipe diameter between 0.5 and 1.5 inches, without the need for additional tools. A patented coupling mechanism allows for torques of up to 8 Nm, ensuring operation even with rusty and old valves.

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.

If the motor is to be used with an EWE shut-off valve, then a special adapter is available for this.
