What impact does abnormal operation of the oil cut-off valve have on screw air compressors?

The oil stop valve is generally a two-position, two-position normally closed solenoid valve. It opens at startup and closes at shutdown to prevent the oil in the oil and gas tank from continuing to spray into the machine head and out from the air inlet when the machine stops. If this component is not opened when loaded, the main unit will heat up rapidly due to lack of oil. In severe cases, it may cause the screw assembly to burn out.
