Motor Servo for Angled Seat Valves
SKU: KFRLWE01
Version: 1.0.0
![](img/lorawan.png)
Product Description
The motor drive designed for angle seat valves, specifically KFR valves, offers a
solution for seamlessly retrofitting existing shut-off valves into remotely controlled
intelligent devices. This process is achieved without the need to interrupt water supply
or cut into the water pipe. The 12V-powered motor is not only water-resistant but also
resistant to dirt, ensuring durability up to the power supply. Versatility is achieved
through various adapter rings and a sophisticated connection system, allowing the motor
to be compatible with modern angle seat valves featuring raising or non-raising stems,
ranging from DN15 to DN32.
Incorporating an additional water sensor directly connected to the device enhances
functionality, enabling the motor to serve as a leak protection system without the need
for further configuration or wireless connectivity. The servo motor's waterproof design
makes it suitable for deployment in damp, dirty, and outdoor environments. In its open
state, the motor autonomously conducts valve training weekly, involving a closing/opening
action by 1/8 turn to remove dirt and scale.
Control is facilitated through local buttons, and remote operation is achieved through
LoRaWAN commands. The device functions as a LoRaWAN Class C device, necessitating LoRaWAN
network coverage for optimal performance. In the absence of existing coverage, the
alternative is to set up and operate a dedicated LoRaWAN gateway.
Beside this the device can be connected directly to Aqua-Scope Leakage Monitors.
