Micro Valves for LC and GC with 90º Flowpath - 4 port

Simplify your liquid or gas handling application with a VICI Precision Sampling Micro valve. In a compact 1” design, the unique fitting detail allows a leak-free seal with no potential for rotor damage from over-tightening. Micro valves come in a variety of flow path configurations (see image), pressure rated to 50 psi for gas, and 100 psi for liquid. Micro valves offer convenient panel mounting (8 mm hole required, max. 4.5mm thickness of the panel mount hole), with internal parts made of PEEK and PTFE. Flowpath configurations Includes fittings for 1/8" OD tubing: 1 PPS flangeless hex-head nuts per port 1 PCTFE collapsible ferrules per port 1 Color-Sleeve adapter per port Specs For 1/16" and 1/8" OD tubing, flangeless connections Wetted Parts Material(s) PEEK, PTFE Body Material POM Nut Material PPS Ferrule Material(s) PCTFE (1/8") or PEEK (1/16") Threads 1/4-28 threads Bore Size 1.50 mm Body Height 44.70 mm Body Diameter 27.94 Pressure rating: 50 psi gas – tested with helium using 1/16" OD x 0.84 mm ID PTFE tubing with PEEK collapsible ferrules 100 psi liquid – tested with isopropanol using 1/8" OD x 0.75 mm ID PTFE tubing with PCTFE collapsible ferrules More Info See Properties of Polymers TECH TIPS Use our impermeable tubing to avoid gas diffusion in the solvent lines While these valves are typically used with collapsible ferrules, inverted ferrules or flanged connections can also be used
