Universal Flat Suction Cup

suction cups sf series mounting accessories

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
