Shimadzu, 228-39093-92, Inlet Check Valve, LC-10ADvp

The Shimadzu LC-10ADvp Pump Inlet Check Valve is a replacement fluidic valve for the inlet side of a compatible liquid chromatography pump head. Its one-way action helps solvent enter the pump chamber during the intake stroke while limiting reverse flow as pressure rises. A valve that sticks or becomes contaminated can produce unstable pressure, reduced delivered flow or poor retention-time precision. During troubleshooting, compare inlet and outlet components separately and inspect the solvent intake path for bubbles, particulates or blocked filters. Before service, stop the pump, release hydraulic pressure and use an approved cleaning or replacement procedure to avoid damaging precision seating surfaces. Reprime the system and verify stable pressure after installation. This inlet valve is a pump maintenance part, not a standalone solvent pump, an autosampler injection valve or a downstream check valve. Compatibility is specific to the LC-10ADvp pump configuration.
