The minimum pressure valve of the air compressor (also known as the pressure maintenance valve) is a key component in the oil-injected screw air compressor.
Features and advantages
1. Ensure the circulation of lubricating oil
When the air compressor is started and running without load, the minimum pressure valve can maintain the minimum
pressure in the system, ensure the normal circulation of lubricating oil, and avoid equipment wear due to insufficient
lubrication.
2. Protect the oil-gas separator
By controlling the gas flow rate, high-speed airflow is prevented from destroying the oil-gas separation effect,preventing the lubricating oil from being taken out of the system, and protecting the oil-gas separation filter element.
3. Prevent gas backflow
It has a one-way valve function to prevent the compressed air in the air tank from flowing back to the oil-gas barrel when the air compressor is stopped or unloaded, avoiding system pressure fluctuations.
4. Improve system stability
The minimum pressure valve can effectively buffer the pressure difference during instantaneous loading, reduce the
impact on system components, and extend the service life of the equipment.
5. Energy saving and efficient operation
By maintaining a stable system pressure, unnecessary energy consumption is reduced and the overall operating
efficiency of the air compressor is improved.
6. Easy maintenance
The maintenance cycle of the minimum pressure valve is usually 8,000 hours, and regular replacement of internal parts
(such as valve core, spring, sealing element, etc.) can keep it running well.
