4.5 Velocity Control Valve

The velocity control valve
adjustment is to control the
inlet velocity of the sample. The
valve is located inside the
refrigerator on the upper right
side of the sample chamber and
can be adjusted by rotating the
knob.
• If the lift height is between 1
and 3 meters, close the valve
all the way (rotate
clockwise), then open two complete
rotations (rotate counterclockwise). The
sampler is always shipped at this setting.
• Open the valve all the way if the lift
height is 1 meter or less.
• Close the valve all the way if the lift
height is greater than 3 meters.
