The stop-turn 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.3.Setting of valve driving voltage and on-off valve time: the lowest driving voltage of the valve shall not be less than 3.0V, and the power supply time of the on-off valve shall not be less than 6s under the lowest voltage, or after detecting the lock-in current, the power supply shall be delayed by 500ms to ensure that the valve is fully opened or closed.4.It is recommended to switch the valve on and off once every month or every two months to allow the valve motor and transmission mechanism to operate once.  InstallationRelative Product   Company ProfileChengdu Zhicheng is one of the world leaders in designing, manufacturing, offering services and solutions in gas meter motor valve industry.
