Outlet valve, 1300 bar. For 1290 Infinity LC pumps. Outlet valve with integrated seal G4220-60028
Agilent G4220-60028 is an OEM outlet check valve with an integrated seal, pressure-rated to 1300 bar. Designed for Agilent 1290 Infinity LC pump heads, it prevents backflow and maintains system pressure integrity in ultra-high-performance liquid chromatography (UHPLC) applications.
Description
The Agilent G4220-60028 is a high-pressure outlet check valve featuring an integrated seal, engineered for Ultra-High Performance Liquid Chromatography (UHPLC) applications operating at pressures up to 1300 bar (18,850 psi). This component is mounted on the pump head of Agilent 1290 Infinity, 1290 Infinity II, and 1290 Infinity III LC systems (including G4220A, G4220B, G4204A, and G7120A modules). It ensures unidirectional mobile phase flow from the pump chamber to the autosampler and column, mitigating pulsation and maintaining precise flow delivery. The valve utilizes an internal gold seal (G4220-20020) and is a key consumable component routinely serviced during pump head maintenance.
