How are the suction and discharge valves of a reciprocating compressor typically mounted relative to the valve plate?

Explanation:
Gas flow and valve action dictate this arrangement. The suction valve is placed below the valve plate so that, during the suction stroke when cylinder pressure drops, it opens and lets low-pressure gas from the suction line into the cylinder. The discharge valve sits on top of the plate so that, during compression when cylinder pressure rises above the discharge line, it opens and allows high-pressure gas to exit into the discharge line. This top/bottom setup aligns valve operation with the two strokes, ensuring proper flow paths and sealing for both suction and discharge.
