EH - Throttle valve
The flow through the vacuum port increases when the suction cup
doesn't contact the workpiece, the valve plate fits the vacuum port,
just little vacuum flow leaks from the small hole
The flow through the vacuum port reduces when the suction cup
sucks the workpiece, the valve plate leaves the vacuum port, and suctioning
the cup usually works. (Suction cup must work vertically when it is
equipped with throttle valve)
EB - Contact inductive valve
When the suction cup doesn't contact the workpiece, the inductive
the valve closes the vacuum port to prevent the vacuum flow leakage
When the suction cup contacts the workpiece, it compresses the valve
rod of the inductive valve, the vacuum port opens, and the suction
cup works normally
