Since there is no air flow, the valve
remains open by the spring force.
When the workpiece is separated
from the vacuum pad, the valve is
closed by the air flow, and the
suction air can only flow through the
fixed orifice. At this time, an amount
of air corresponding to the fixed
orifice size is sucked.
When the workpiece is sucked by
the vacuum pad, the suction flow
reduces, and the valve is opened by
the spring force, which opens the
path between the valve and body for
suction.
When the workpiece is released,
the valve is opened by the vacuum
breaking air, and the path between
the valve and body will open.
