Solenoid valve failure analysis

The electric valve is composed of an electric actuator and a valve. The failure of the electric valve is more on the electric actuator. The following is a detailed analysis of several common reasons for the failure of the electric valve device. Analysis of the failure causes of the electric valve device: 1. The component pins on the circuit board are oxidized, and the circuit board itself is disconnected due to material and temperature changes, which will lead to electronic product failure; 2. In terms of product selection: the power of the product is too small, and the operating torque cannot meet the needs of valve starting; the withstand voltage range of the product is too narrow to meet the objective use requirements of gas field stations located in special areas such as towns; 3. Product manufacturing: the manufacturing accuracy of individual products cannot meet the requirements, and the sealing is not strict; 4. The operation, maintenance, and general troubleshooting skills of the on-site operators need to be improved.
