Intelligent Suction Valves
SMC has released a
range of “ Intelligent suction check
valves”.
The ZP2V valve units
are used where multiple cups are run off a single vacuum source, they are used
to help prevent excessive vacuum leakage though the cups that do not correctly
seat on a work piece.
This unit is fitted
between the vacuum generator and the suction cup.When the suction cup seals against the work
piece, the check mechanism opens, and full vacuum is applied to the cup.
If there is no work
piece present or the work piece is dislodged/removed during operation the ZP2V
valve will close/stay closed, to help prevent large vacuum leakage allowing the
rest of the vacuum cups to operate with minimal vacuum loss.
The design of the
product means that they can still be used where vacuum blow off is needed to release
the work piece.
