STREGA reveals a new edition of its IoT LoRaWAN shutoff smart-valve for critical operation.

With Class C, the valve opens or closes with no latency when a command is requested by the Command Center. And more: with its wired leak detection sensor, digital inputs or analog 0-10VDC reading, the STREGA smart-valve can trigger an immediate closing or opening even if no network is reachable.

Featuring LoRaWAN low power consumption, the STREGA valve communicates on extreme distances inside urban areas with deep indoor propagation of the signal.

For time-controlled automatic operation, the smart-valve has an embedded agenda where “scheduled” open/close is stored at valve level.
