Atlas Copco air compressor Cover Valve Part 1614822200

Main function

Intake and exhaust control:

In piston-type air compressors, the cover valve usually integrates the intake valve and the exhaust valve. Through the opening and closing of the valves, in coordination with the piston movement, it accomplishes the gas intake (when inhaling, the intake valve opens and the exhaust valve closes) and compression and discharge (when discharging, the exhaust valve opens and the intake valve closes), which is the core component for achieving the gas compression cycle.

Pressure sealing:

The sealing surfaces of the valve and the cylinder cover are sealed by gaskets or precise fits to prevent the leakage of compressed gas and ensure the pressure efficiency within the cylinder, avoiding the reduction in compression capacity due to leakage.

Overload protection:
