Description: Core wear part of pump-head check valve, operates paired with valve seat for unidirectional media on-off control.
Responds to pump-chamber pressure differential: lifts open for media suction and discharge; re-seats tightly against valve seat upon closing to block high-pressure-media reverse flow, stabilizes pump output pressure and flow rate. Withstands repeated high-pressure impact and sustains metering-pressure accuracy.
316L stainless steel, cemented carbide or ceramic options. Conical or spherical geometry; precision-machined contact surfaces with high hardness and erosion resistance.
