Compact, Low Profile Flow Control Valves
ROSS flow control valves provide high air flow rates into a cylinder, and
precisely controlled flow rates out of the cylinder. The adjustable flow
can range from near zero to full flow.
Selecting flow control valves with sufficient
flow capacity is important so that they do
not become the limiting factor in the cylinder
control system. Full flow capacity should
match that of the control valve to keep
cylinder motion smooth and predictable in
both directions.
