Weigh Diverter / Fill Pass Valve

The weigh valve is primarily used in bulk handling systems whereby a product is pneumatically conveyed to a hopper or bulk bin which is process weighed.

Description

Initially the valve is positioned as per Fig 1 showing the product being discharged into a bin while the air is exhausted. On the correct weight being designated the valve changes position by means of the single cylinder to the position as per Fig 2. In this case the correct weight has been established and the product is then either sent to alternative weigh stations or conveyed back to its holding hopper.
