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.

Brass Micro Control Valve (BMCV) - Manual Operation          

The BMCV-1 mini-valves are ideal for on-line microcontrol such as septum purge and non precision flow control. The valve accepts 1/16" OD flow lines.

The BMCV-1 can provide smooth flow metering up to 2 litre/min.

On/Off valve  (MOVP) - Pneumatic Operation           

The MOVP and MOVPT valves have a similar design to the MOV and MOVT except the on/off function is actuated pneumatically.

They can be actuated remotely with a toggle switch or solenoid valve, and a 50-55 psi air supply.
