The main function of the solenoid valve is to control the switch. It is very popular because of its simple structure and small size and easy installation. Some customers report that the solenoid valve cannot be closed or opened after installation. Here is an analysis of the reasons why the solenoid valve cannot be closed or opened

The reason why the solenoid valve cannot be closed:

① It is reversed

The solenoid valve cannot be installed in reverse direction. During installation, the arrow on the valve body should be consistent with the flow direction of the pipe fluid. The coil should be installed vertically and horizontally

② Card stuff

If there are foreign particles in the medium, the valve port will be stuck out, which will lead to failure to close or open. Disassemble the solenoid valve, clean it, and then install it (the solenoid valve requires the medium to be clean. If there are small impurities and dust in the medium, the filter provided by "our company" must be installed in front of the valve (filter screen ≥ 80 meshes/cm2).)

③ Incorrect pressure

Is the pressure standard? Full direct acting solenoid valve shall be selected for zero pressure and steam

The reason why the solenoid valve cannot be opened:

① Incorrect pressure

Is the pressure standard? Full direct acting solenoid valve shall be selected for zero pressure and steam

② Wrong voltage (wrong voltage, insufficient power)

Before installation, check whether the pressure, temperature and voltage are consistent with the nameplate and actual parameters of the solenoid valve. The length of the DC power line should not be too long to avoid power loss of the coil and voltage drop affecting the normal operation (DC24V should not exceed 30m).

③ Card stuff

If there are impurities in the medium, the valve port will be stuck out, which will lead to failure to close or open. Disassemble the solenoid valve, clean it, and then install it
