Water solenoid valve installation instructions:
1, the installation of the solenoid valve coil up and maintain the
vertical position, the solenoid valve arrow or mark shall be
consistent with the flow of the pipeline can not be installed in a
splash of water or the leak.
2, the working medium of the solenoid valve should be clean and
free of particulate impurities, dirt and member of the
electromagnetic valve on the filter surface, requiring regular
clean.
3, when the solenoid valve fails to timely isolation solenoid
valves, and ensure the normal operation, it is best to install a
bypass device.
4, in the pipeline system, installed in the branch on the way
solenoid valve diameter should be less than the main pipe valve
diameter.
5, before installing solenoid valves, pipes must be cleaned. It
recommended before valve mounting filters, steam trap piping
installation.
6, the valve can not be installed in the lower recesses of the
pipe, so as to avoid steam condensate and impurities precipitated
and hinder valve operation.
7, it can not be used in explosion hazardous areas.
8, in the lack of rigid pipe, it is recommended to use the valve
before the pipe bracket, so as not to cause vibrations when the
solenoid valve is working.
9, prior to installation, pay attention to see the product label,
carefully read the instruction manual to determine whether the
product meets the conditions of use.
10, before and after the valve pressure gauge to be installed on
the pipe, in order to observe the pipeline pressure
