MACGREGOR – SUCTION VALVE SPRING – COMPRESSOR SPARE

The MacGregor Suction Valve Spring is a precision-engineered helical spring spare designed to deliver rapid, consistent valve closing force within marine air compressor suction valve assemblies. Manufactured from high-tensile, fatigue-resistant spring steel alloy, this heavy-duty spring is built to endure millions of high-frequency compression cycles without experiencing tension loss or micro-fracturing under intense engine room vibration and elevated operating temperatures. Tailored for direct fitment within MacGregor marine air compressor intake valves, it ensures accurate valve timing, prevents intake backflow, and maintains an airtight seal when closed. By optimizing cylinder intake efficiency and preventing valve flutter, it preserves peak volumetric compression, reduces energy consumption, and extends overall valve train service life for commercial shipping vessels, cargo handling machinery, and offshore marine installations.
