Product Detail


Measuring Grade: Class 2

Working Water Temperature: Water Temperature 0-50 C

Nominal Pressure: <0.1 MPa

Closing time: 30S

Opening time: 30S

Pressure loss: <0.1 MPa

Static Power Consumption: <0-5 UA

Performance characteristics

1. Using large-capacity chips to reduce peripheral circuits has high reliability and low failure rate.

2. Low power valve, flexible switch, strong reliability, long service life.

3. Double display, double display of wheel and LCD, higher reliability and safety.

Intelligent Function

1. Auto-switch: recharge water for opening valves, no value for closing valves, auto-switch valves; pre-charge water, no need to enter the home meter reading, charging.

2. Encryption security: One table (one household) and one card automatically generate and identify IC card passwords, which correspond to each other and are not interchangeable.

3. Anti-magnetic interference: When magnetic interference occurs, the valve closes automatically and opens automatically after swiping the card.

4. Early warning: When the remaining water is 20-50m3 (set according to user's requirements), the valve is promptly closed, reminding users to buy water as soon as possible; at this time, the card can be switched on and the valve can continue to use water.

5. Low-power warning: when the power is insufficient, the LCD display is insufficient, prompting the timely replacement of batteries.

6. Low power shut-off valve: If the battery is not replaced in time after low power warning, the valve will be closed and the battery must be replaced before the valve can be opened for water supply.

7. LCD display: LCD display accumulative amount of water, residual water, valve switch, power status, fault code and other information.

8. Query display: the display is usually closed, and the user card is used to show the amount of residual water and cumulative consumption.

9. Anti-clogging function: Control program automatically cleans the valve to keep the valve flexible.

10. Data write-back: User card can write back the data of water meter. It can read the working state of water meter in management system, which is convenient for management.

11. Management card function: inquiry card and transfer card are used by managers in inquiry and maintenance.
