Instruction For Use
1.Two-line, four-line and five-line models are available for this type of valve. The red wire is connected to positive power (or negative power), and the black wire is connected to negative power (or positive power) to open the valve (specifically, it can be set according to customer needs). The other 2 or 3 wires can be signal wires of open/close.
2.Four-wire or five-wire valve opening and closing process time setting: When opening and closing the valve, when the detection device detects that the opening or closing valve is in place, it needs to delay 300ms before stopping the power supply, and the total time of opening the valve is about 1s.
3.The minimum drive voltage of the valve shall not be lower than 3V. If the current limit design is in the process of opening and closing the valve, the current limit value shall not be lower than 120mA
4.The motor valve opening and closing can be judged by detecting the locked-rotor current in the circuit. The locked-rotor current value can be calculated according to the working cut-off voltage of the circuit design, which is only related to the voltage and resistance value.
