The Finest Needle Valves Ever

May 13 2014

For many years, designers of GC & GC/MS and other analysis systems have had to modify their schematics to avoid the use of needle valves due to the lack of supply of good, repeatable and reliable valves. This is no longer the case and there are still applications where only a very fine valve that opens with no burst can be used.

Chell's CMV has been refined over the years, even including automated computer-controlled opening and closing plots in order to guarantee the quality of its performance. With the finest needle giving 0-20sccm over 20 turns, this is the finest control valve ever produced.

For those requiring miniature tube couplings, Chell has produced many thousands of couplings for dedicated applications in the aerospace industry that are equally applicable to gas analysers. Construction is in S316 or S321 stainless steel for tube diameters of 1/16” and 1mm and the design has the absolute minimum of dead space within the flow path.
