CYLINDER HEADS & VALVES

Intake and compression valves are made of annular discs which operate automatically.
Good water-tightness is necessary between the discs and their seats (avoid running the compressor
with clogged valves, with carbon deposits, oil carbon or more importantly, with broken valves).

Low Pressure stage

High Pressure stage
