IOT Smart Remote-Control Valve for Gas Pipeline System
Product Description
The IoT intelligent control safety valve is a product with ultra-low power consumption, compatible with NB-IoT and 4G remote communication (can realize seamless replacement), high reliability, long service life, and can be customized according to requirements; the product reserves a variety of The interface can be used for connecting external devices to realize the monitoring and control of external devices.
Main features:
1. The power consumption of the product belongs to the ultra-low power consumption level;
2. Using dot matrix liquid crystal, characters or symbols can be combined arbitrarily;
3. The communication module is independent, which can realize rapid replacement and adapt to different environmental requirements;
4. Built-in Bluetooth near-field communication, direct communication and interaction through mobile phone or tablet;
5. Remote control and local IC control can be interchanged;
6. All control functions are completed locally without time delay;
7. There are many options for power supply (primary lithium battery power supply or external power supply);
8. The communication module antenna installation method is optional (built-in antenna or external antenna);
9. The supporting valve is a slow-opening and fast-closing valve, and the closing time is ≤2s;
10. The matching valve body is made of cast aluminum alloy, which is light in weight and good in corrosion resistance, and can withstand a nominal pressure of 1.6MPa; the overall structure is resistant to impact, vibration, high and low temperature, salt spray, etc., and can adapt to various complex outdoor environments;
11. The control parts can be rotated, and the air intake direction can be adjusted to adapt to various installation environments.
