Agilent, G1312-60025, Active inlet valve, without cartridge

Agilent's active inlet valve body is a replacement component for compatible 1100, 1200 and 1260 Infinity LC pump assemblies. It controls the inlet side of the pump-head solvent path together with a separately installed valve cartridge. The supplied component does not include the cartridge, so a maintenance job may also require the correctly rated cartridge for the particular pump. This distinction matters because the cartridge pressure specification can differ between pump models. The active inlet valve body should not be confused with a passive inlet check valve, an outlet valve or a complete pump-head assembly.
