Retrofittable motor for ball valve (remote control via contact controller)
SKU: BVSDRY02
Version: 1.0

↑1. Product Description
This motor converts existing and installed ball valves into intelligent water control
devices. Thanks to the innovative clamp mechanism, it can be installed on shut-off valves
with a pipe diameter between 0.5 and 1.5 inches within minutes, without the need for
additional tools, and can be removed just as easily. A patented coupling mechanism allows
for torques of up to 8 Nm, enabling it to function even with rusty and old valves.
The servo motor is waterproof and can be used in damp, dirty, and outdoor environments.
In the open position, the motor automatically performs valve training once a week
(closing/opening by 1/8 turn to remove dirt and scale). The device is also capable of
measuring the rotation angle and detecting the end positions of the lever. It approaches
the end positions slowly to avoid friction and unnecessary mechanical stress. It is
powered by an external 12V power supply through a waterproof coupling.
The device is controlled either through the local button or a switch input on the
'Dry Contact Controller.' The connection between the Dry Contact Controller and the actual
motor is established through an encrypted LoRa wireless connection. This robust wireless
technology allows for seamless motor control through multiple walls or in the garden.
