Save Energy, Reduce Air Consumption: SMC’s Vacuum Savings Valve
As children, we were told repeatedly to "turn off the lights
when you leave a room." It was sound advice then, it is sound
advice now. Translating this command to our machinery can be a
challenge though; however a new "smart valve" Series ZP2V,
developed by SMC, has mastered this command. How does the ZP2V
work? It detects when a part needs to be picked up and turns "on"
and when it sees that a part does not exist to be picked up, it
In this example, only the ZP2V valves touching the blue disk are
activate. Those that are not exposed to the blue disk have
significantly decreased air flow.
When no part is present, the vacuum
air flow closes the check valve which restricts but does not
totally eliminate the air flow.
The reduction of air flow
substantially reduces air consumption in the vacuum system.
When a part is present, the vacuum air flow is reduced further
which allows the spring to overcome the air flow. This causes
the internal check valve to open fully and full vacuum flow will
Beyond acting as a great energy saver, the ZP2V can be
used as a "fail safe". Here's how. Because the vacuum
flow is restricted when the work piece is not present, a cup
failure causes high flow to be present and therefore the flow would
be restricted. The rest of the vacuum cups would function
Using the ZP2V would allows users to pick up multiple
sized parts with the same system. Just as detailed above, it
restricts the vacuum flow to the vacuum cups that are not being
used and the vacuum cups that are being used would function
SMC's vacuum saving valve is a smart and easy way to
reduce air consumption.
The ZP2V is available in:
- 5 different thread options (M5, M8, R1/8, G1/8 and
- 4 orifice sizes are available (0.3mm, 0.5mm, 0.7mm and
Note: The Vacuum Saving Valves are stocked in the US
for quick delivery.
