Smart Wi-Fi Water Shut-Off
To transform leak detection into active protection, the system integrates with the Stahlmann™ Smart Wi-Fi 12V motorized ball valve.⁠
Coming Soon
Smart Wi-Fi Water Shut-Off
Core Features:
  • Bronze full-bore construction (PN 40 bar)
  • 12V DC low-voltage operation
  • Manual override capability
  • Automatic monthly anti-seizing cycling
  • 10-year manufacturer warranty
System Function:

When connected through Smart Life / Tuya automation, a leak signal from the sensor triggers immediate valve closure — isolating the water supply automatically and minimizing potential damage.

This creates a complete detection-to-response workflow within a unified smart ecosystem.
