● Valves
Slow opening and fast closing valves ensure reliable valve closure within 2 seconds under medium and high pressure loads.

● Zero pressure loss design
The valve diameter is the same as the pipeline diameter to achieve low pressure loss in the gas passage.

● Anti wire breakage design
The flowmeter and controller are connected with anti disconnection, and the valve is immediately closed after disconnection.

● Wide applicability
At the same time, it can be used in conjunction with intelligent gas waist wheel flow meters, intelligent gas turbine flow meters, rotary flow meters, etc. to form a prepaid system, with specifications ranging from DN25 to DN200.

● High work pressure
The conventional pressure is 0.4 MPa, and the maximum pressure can reach 0.6 MPa.

● Software compatibility
The gas sales management software is fully compatible with household ICW management software, and the operation can be remotely monitored.

● Remote monitoring
NB IoT or 4G IoT communication modules can be installed to achieve remote monitoring, remote meter reading, remote recharging, remote valve control and other functions, providing reliable guarantees for gas companies to achieve big user data monitoring and gas analysis.

● Complete functional cards
Multiple types of functional cards can be issued, including user cards, price adjustment cards, suppression cards, transfer cards, etc., to meet various functions.

● Settlement mode
There are two trade settlement modes to choose from: amount (yuan) and gas volume (m ³). The amount settlement mode supports tiered gas price and gas price adjustments.
