Micro Control Valves

SGE's microcontrol valves provide precision metering and on-off control of gas flows. They are designed specifically for chromatography applications and may be used at elevated temperatures from high vacuum to medium pressure.

The valves are vacuum rated to a leak rate of 1 x 10-5 cc/sec of Helium except for BMCV and SMOV, which are not tested for this application.

For on/off control or metering of a single gas stream, choose an "L" configuration, i.e. BMCV; SMOV; or MOVP.

If the application requires diversion or splitting from the main stream of gas to another column or detector and so on, choose a "T" configuration, i.e. MOVPT.

NOTE: In valves of the "T" configuration, flow through the cross arms continues whether the valve is "open" or "closed". Metering only occurs on the vertical arm. The relative flows between the side arm and the vertical arm when the valve is opened will depend on the relative restriction in the flow lines downstream of the valve.

  • Minimal exposure to stainless steel
  • Fully swept flow path
  • Replaceable graphitized VespelĀ® seat
  • Range of stem lengths where appropriate
  • Easy installation
  • Maintenance instructions, spare seals and seats are provided with each unit
  • Minimal dead volume
