Valves, Chem-Vac, High Vacuum, Low Hold Up

Similar to CG-927 CHEM-VAC™ valve but with the arms bent to minimize hold up of fluids.  Valve has TFE plug with three o-rings, the tip o-ring making the primary seal on the precision formed tapered seat.  O-rings on the non-rotating shaft form an excellent dynamic seal between the TFE plug and glass barrel.  Available with a choice of Viton, Ethylene Propylene (E.P.) or Kalrez® o-rings.  See CG-935 for replacement plug, CG-537 for o-ring replacement kit, and CG-905 for glass portion only.
