Shut-Off Valve

EXTREME RANGE WIRELESS SHUT-OFF VALVE

Sahara Emirates is supplying the STREGA LoRa wireless smart valve which is a battery operated valve of industrial grade quality and of exclusive design with embedded LoRaWAN wireless technology and automation features. Supplying Shut-Off Valve all over UAE (Dubai, Abu Dhabi, Al-Ain, RAK, & Sharjah).

 

With its ultra-low-power consumption, the valve can operate on batteries during 10+ years and through extreme long distances with an exceptional obstacles penetration, even inside buildings or urban areas.                                                                                                                                                                                                    With its additional Digital and Analog inputs, like a pressure or a humidity sensor, for instance, the valve can be turned off at the main line stopping the leak before major damage is done and at the same time, send an alarm to your Mobile through the gateway or the Application Server. The valve may also be configured for full water meter reading and data transmission capabilities, eliminating the need for a discreet endpoint.The STREGA Smart-Valve  can be programmed for automatic shut-off based on counter value.

The STREGA smart-valve combines long range LoRa LPWAN communication with an ultra-low power design. This wireless valve runs on Lithium batteries for 10-15+ years (or with no time limit if powered externally) while transmitting several parameters like valve its status (Open/Close), device ID (unique AES128 encryption key), battery level, signal strength, enclosure tampering (is the box tentatively open for fraud ?), alarm, leak detected, pressure level, ambiant temperature, counter value, etc.

​

A leak detection, for instance, can immediately trigger the closing of the valve and report the issue to its owner.  You can control back the smart-valve from a Control Center or from a secure link via your mobile phone and tablet.

 

​

Your STREGA valve is also capable of automatic operations such as decrementing a preset counter value representing the permitted monthly amount of liters and performing an automatic closing when the allowed amount is reached. This counter preset can be modified on-air at any time.
