SMC Pneumatics ZP2V suction valve units

Click2Contact

ZP2V suction valve units are used where multiple suction cups are run off a single vacuum source. They are used to help prevent excessive vacuum leakage through the suction 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 work piece. They are designed to be effective in applications where different-sized work pieces are used with a single suction cup arrangement.

If there is no work piece present or the work piece is dislodged or removed during operation, the ZP2V valve will close or stay closed, to prevent large vacuum leakage and allow the rest of the vacuum cups to operate with minimal vacuum loss.

The design of the ZP2V means that they can still be used where vacuum blow-off is needed to release the work piece.
