Technical Data for MCV & MCVS Mass Flow Controllers

0 to 0.5 sccm Full Scale through 0 to 20 slpm Full Scale

The Alicat

MCV

mass flow controller is designed for applications that require tight shut-off such as vacuum

coating and sputtering processes. An integrated pneumatic shut-off valve is normally closed and provides

positive shut-off of 1 x 10
