For fine control of fluid flow rates, our Micro-Metering Valves can reduce outgoing flow to as low as 3.5 µL/min. These needle valves are perfect for use with peristaltic pump fluid-transfer applications, mass spectrometry, and fraction collection.
Upchurch Scientific® Micro-Metering Valves can also be used to regulate gas flow in helium sparging lines and as a flow-dependent variable back pressure regulator. For flow independent regulation of back pressure.
Flow path materials are PEEK polymer and PTFE (O-rings). All versions of this valve have 0.020" thru-holes.
