Weigh Valves from Rotolok Valves

11 January 2021

The weigh valve is a natural development from the Rotolok series of pneumatic Conveying Diverter Valves. These valves are primarily used in small bulk handling systems where a product is pneumatically conveyed to a hopper or bulk bin which is process weighed. 

Initially the valve is positioned so that the product is being discharged into a bin whilst the air is exhausted. On the correct weight being achieved, the valve changes position by means of the single cylinder.

Other diverter valves include:

Conveying Diverters – Directional branch valves for conveying lines.

Plug Diverters – For Pneumatic applications where high pressure or abrasive products are a consideration. 

Gravity Diverters – Diverter for chute applications routing solids in free fall.
