Solenoid valve can not open the fault cause is

The important role of the solenoid valve is to control the circuit. It is popular because of its compact structure, small size and easy installation. Some customers report that the solenoid valve cannot be closed or opened after installation. Let me analyze for you whether the solenoid valve is closed or not. The main reason why you can't open it. 

Solenoid valve can not close the main reason:. 

1. It is installed backwards. 

The solenoid valvecannot be installed in the opposite direction. When installing, pay attention to whether the arrow symbol on the oil circuit board is consistent with the pipeline liquid inflow, and the solenoid coil is installed vertically and horizontally. 

2. Residue medium. 

If the medium contains residual particles, the valve may become stuck, preventing it from closing or opening. Remove and clean the normally open solenoid valve, then install it (Solenoid valve has a relatively clean medium requirement. If the medium contains fine debris, before the valve, the dust must be installed by "our company" filter device (screen ≥80 mesh /cm2). . 

3. The pressure isn't right. 

The pressure is not standard. For zero pressure and steam, choose a fully direct acting solenoid valve. 

Large solenoid valve can not open the main reason:. 

1. The pressure is not right. 

The pressure is not standard. For zero pressure and steam, choose a fully direct acting solenoid valve. 

2. Working voltage error (working voltage error, insufficient output power). 

Before installation, check whether the pressure, ambient temperature, and working voltage are consistent with the factory nameplate and actual parameters of the solenoid valve. 30m). 

3. Residual medium. 

If the medium contains residue, the valve may become stuck, preventing the valve from closing or opening. Remove and clean solenoid valve, then install.
