Products Description
When an air compressor stops, if the high-pressure compressed air remaining in the oil-gas separator flows back into the main unit, it can cause the screw to reverse-one of the most serious damage modes for the main unit. This can cause minor bearing wear or, in severe cases, direct damage to the rotor profile. The check valve function of the intake valve is the first line of defense against this "backflow" accident.
The 1622075901 design prioritizes "reliable shut-off," integrating intake regulation and check valve functions. During normal operation, it throttles and controls the intake air volume, achieving precise loading and unloading adjustments. When the compressor stops, the valve disc automatically resets under pressure differential, cutting off the airflow passage and preventing compressed air from flowing back into the main unit and causing reverse rotation damage.
