Vacuum safety valve

The Vactrap is a check valve which is also equipped with a built-in blow-off valve to provide quick release of an object. It is also available in a special version in which the vacuum pump and blow-off connections are interconnected (x-drilled), making it suitable for ejectors with an integrated blow-off valve, such as PIAB’s AVM models. The Vactrap can be used in an existing centralised vacuum system with external blow-off possibilities and it is also possible to get it with an integrated Pi12-2 COAX cartridge for decentralised vacuum systems.

The Vactrap ‘traps’ the vacuum pressure in Vacuum systems for an indefinite period of time in non-porous applications, such as when handling sheet metal or glass with suction cups, even if the supply of compressed air should be cut off, if a pump failure should occur or if the emergency stop should be activated, thus preventing the object from being dropped. The object can be handled with a high degree of safety. The industry which will benefit the most from these products is the automotive industry but many industries where non-porous materials are handled can also benefit from its features.

The valve makes it possible to transport non-porous objects between various operations with no need of attachment to an energy source. The risk for injuries and material damages is reduced considerably since the Vactrap allows non-porous parts to be handled safely even in the case of system interruption or failure.
