Chell has created a range of precision needle valves capable of repeatably delivering precise flows. The valves provide gas flow control from 0-20sccm to 0-3slpm at 1 bar differential. All feature stainless steel construction with Perlast seals as standard, with other seal materials are available on request.
Designed for use in pressure or vacuum applications, they are ideal for gas analysers, chromatographs and mass spectrometers - in addition to any application where fine control is required.
