Shimadzu, 228-35443-91, 电磁阀 VALVE,FCV，用于LC-20AD

Shimadzu FCV solenoid valves are service components for the controlled fluid-handling functions of compatible liquid chromatography pump systems. This valve is specified for the Shimadzu LC-20AD pump. Within the pump assembly, proper valve operation is necessary for the intended liquid-path switching and instrument control behavior. Malfunction can interfere with priming, flow-path management or normal operation, depending on the instrument's control sequence. The replacement part is supplied as one valve. When diagnosing a fluidic fault, verify the instrument error condition, affected flow path, electrical connector and related tubing before replacing the component. Use the LC-20AD maintenance procedure, relieve system pressure, and isolate solvents and electrical power before disassembly. Reconnect the valve using the original routing and fittings, then inspect for leaks and run the required pump operational tests. Do not apply generic solenoid specifications or substitute valves from other pump models without explicit manufacturer compatibility information.
