Vici Valco 6 Port Injection Valve Flow Body 5000 Psi with 1/16 in. Ports

Description

VICI Valco 6-Port Injection & Switching Valve Flow Body – 1/16 in. Valco Fittings, 5,000 psi Max Pressure, Stainless Steel, Standard Bore (MPN: 10U-0971V)

The VICI Valco 10U-0971V is an instrument-grade, high-pressure 6-port chromatography injection and switching valve flow body engineered for high-performance gas chromatography (GC) and liquid chromatography (HPLC) fluidic manifolds. Designed as a standalone replacement flow-body chassis, this precision component features a standardized 6-port geometric configuration optimized for 1/16 inch Valco internal capillary fittings. Machined from high-purity, passivated stainless steel, the 10U-0971V is structurally rated to handle continuous analytical system backpressures up to 5,000 psi. Its ultra-smooth internal conical bore ensures perfect, zero-dead-volume mating with internal polymer rotors, eliminating sample carryover, defending against localized micro-leakage, and maintaining absolute baseline stability across high-sensitivity detector loops.

Technical Performance and Design

• Universal 6-Port Sample Loop Geometry: Engineered in a standard 6-port circular arrangement, providing the baseline mechanical architecture for routine sample injection loops, column backflushing arrays, and dual-column switching pathways.

• 5,000 psi Structural Pressure Rating: Fabricated to maintain absolute dimensional integrity under demanding automated laboratory backpressures up to 5,000 psi, making it highly effective for standard analytical HPLC and high-pressure GC carrier lines.

• Precision 1/16 in. Valco Port Threading: Outfitted with proprietary Valco internal nut and ferrule thread entries. This specialized seating allows for flush capillary connections that eliminate hidden dead-volume pockets, preventing peak broadening and split peaks.

• Passivated Stainless Steel Matrix: Constructed from premium, chemically inert stainless steel. The fluid-contact pathways exhibit high resistance to aggressive mobile phases, salty buffers, and volatile organic solvents, preventing metallic ion leaching.

Key Benefits and Applications

• Chromatography System Rebuilds: The ideal replacement flow body for restoring factory-spec sealing performance to manual injectors or automated pneumatic/electric actuator valves when the original stator face becomes scratched or pitted.

• Aseptic Flow-Path Registration: The highly polished conical interior allows the matching polymer rotor to slide seamlessly between sample “Load” and “Inject” alignments, minimizing mechanical rotor wear.

• Automated Column Switching: Extensively utilized as an inline routing matrix to cleanly shift mobile phases between separate analytical columns or to execute backflush sequences without breaking down the plumbed fluid line.

• Preserved Peak Symmetry: Eradicates microfluidic turbulence within the port pathways, helping labs achieve tight reproducibility, sharp analytical resolution, and accurate target analyte integrations.
