Atlas Copco MPV Kit This kit typically includes the main components such as the minimum pressure valve body, seals, springs, and valve cores. Its main functions are:
Establishing system pressure: During the startup phase of the air compressor, the minimum pressure valve remains closed, helping the unit quickly establish internal pressure and ensuring that the lubricating oil can circulate normally, lubricating all moving parts.
Stabilizing system pressure: When the system pressure reaches the set value (usually 0.4 to 0.6 MPa), the valve automatically opens, delivering compressed air to the air storage tank and downstream systems, while maintaining the minimum working pressure within the unit.
Preventing reverse airflow: When the unit is shut down, the minimum pressure valve automatically closes, preventing the compressed air in the air storage tank from flowing back into the air compressor, avoiding unit reversal or the loss of lubricating oil.
