Product Overview
The Agilent G1312-60025 is an Active Inlet Valve engineered for the Agilent 1260 Infinity and 1200 Series HPLC pump modules, where it serves as the primary fluid control element governing solvent intake during the pump’s fill stroke. This active inlet valve operates on an electronically actuated solenoid principle, opening and closing in precise synchronization with the pump’s cam-driven plunger motion to deliver accurate, reproducible solvent delivery at flow rates up to 10 mL/min and system pressures up to 600 bar. Unlike passive check valves that rely solely on pressure differential, the G1312-60025 actively controls the inlet timing, eliminating check valve sticking and improving retention time precision in demanding analytical and process-scale liquid chromatography systems. As a genuine Agilent replacement component, it is a direct-fit assembly for the G1312A and G1312B binary pump modules.

Engineering Features & Advantages
- Active Solenoid Timing: Electronically driven valve actuation ensures precise opening and closing synchronized with the pump stroke, eliminating the check valve sticking and flow pulsation common to passive inlet check valves.
- High-Pressure Sealing Integrity: Sapphire and PEEK sealing surfaces maintain leak-free performance at pressures up to 600 bar, preserving volumetric efficiency and retention time reproducibility.
- Superior Solvent Compatibility: Chemically inert wetted path supports aggressive mobile phases including high-salt buffers, acidic and basic modifiers, and reverse-phase organic solvents.
- Industrial Reliability: Designed for continuous duty in high-throughput analytical laboratories, with a service life rated for millions of actuation cycles.
- Direct Fit Replacement: Precision-manufactured to original Agilent specifications for direct replacement, minimising downtime and eliminating fitment issues.
Typical Industrial Applications
Unlike passive check valves that rely solely on pressure differential, the G1312-60025 actively controls the inlet timing, eliminating check valve sticking and improving retention time precision in demanding analytical and process-scale liquid chromatography systems.
