The Shimadzu Inlet Check Valve (228-48249-96) is a precision-engineered one-way valve designed for Shimadzu HPLC pumps, including LC-20AD/AB XR, LC-30ADSF, i-Series, and LC-40D systems. During the pump suction stroke, the valve opens to draw fresh mobile phase into the pump head and closes during the delivery stroke to prevent backflow toward the solvent reservoir. A properly functioning inlet check valve ensures stable pressure, smooth flow delivery, and consistent chromatographic performance. Routine replacement during preventive maintenance helps eliminate pressure fluctuations, baseline noise, and flow inconsistencies caused by worn or contaminated valves.
