Quick Release Device, QR series

The economic solution specially developed for micro-ejectors ensures the quick return of the vacuum network to atmospheric pressure in vacuum systems requiring limited space and lightness.

Working Principle

When pressure is applied to the ejector for vacuum generation, the internal valve of the QR18 engages, preventing contact with the atmosphere. When the pressure for vacuum generation is cut off, the system automatically opens to the atmosphere, and the vacuum network is dumped.

Advantages

• Ensures fast and automatic dumping of the vacuum line to the atmosphere
• Shortens cycle times
• Eliminates the need for a blow-off valve
• Check valve control synchronized with the ejector supply
• No energy consumption
• Easily removable structure for cleaning
