Venturi Powder Control Valve

LIAG® Venturi powder control valves are designed to enable smooth flow of powder through the valve, the middle port is orientated at a 135°/45° angle to the straight through passage. The Y-Arrangement of the inlet creates the ideal flow and vaccum exhaust characteristics for proportioning and dosing. This allows for a complete full bore without reducing the nominal diameter as often experienced with the use of a butterfly valve. Furthermore the Venturi powder control valve can replace up to two Butterfly valves, which improves the operating control of the unit.
