FAQs

Question: Which pump family uses this valve?

Answer:Compatible Infinity quaternary and flexible LC pumps, including G4204A and selected G7104 models.

Question: What does the valve control?

Answer:One-way mobile-phase entry into the pump head during piston refill.

Question: Is it identical to inlet valve G1312-60066?

Answer:No. The two valves serve different Agilent pump configurations.

Application Note

Agilent passive inlet valve is a service component for compatible Infinity, Infinity II, and Infinity III quaternary or flexible LC pump platforms. It manages the entry of solvent into the high-pressure pump-head chamber during reciprocating piston movement. Proper inlet-valve function supports stable pump priming, reproducible mobile-phase delivery, and low-pressure-ripple operation in gradient chromatography. This configuration is associated with the 1290 Infinity Quaternary Pump G4204A and selected G7104-series pump models. Replacing the inlet valve may be appropriate when cleaning and pump diagnostics identify inconsistent filling or an inlet-flow fault. Its application differs from inlet valves designed for conventional 600 bar 1260 pumps. This is an individual valve component rather than a long-life pump head or complete pump module.
