The AST solenoid valve ZD.02.009 is an important component for emergency shutdown of the steam turbine. Therefore, regular maintenance and monitoring of the solenoid valve are necessary in daily use to promptly address any faults and ensure the normal operation of the system.

Yoyik has summarized some common faults that may occur with AST solenoid valves, hoping to be helpful to your use of solenoid valves.

• 1. Valve blockage: The internal passages of the solenoid valve may get blocked due to impurities, dirt, or deposits in the oil, causing the valve to fail to fully open or close. This may result in abnormal steam flow or the valve not functioning properly.
• 2. Valve leakage: Poor sealing or aging and damaged seals of the solenoid valve may cause leakage at the valve.
• 3. Valve sticking: The piston or diaphragm of the solenoid valve may become stuck or adhere, causing the valve to fail to open or close. This may occur due to prolonged periods of non-use or component wear.
• 4. Circuit faults: The circuit of the solenoid valve may experience poor contacts, short circuits, open circuits, or other electrical issues. This may cause the solenoid valve to fail to respond to control signals or work properly.
• 5. Drive issues: The drive components of the solenoid valve, such as the solenoid or coil, may be damaged or aged, resulting in the solenoid valve not functioning properly.
