Liag venturi valves for powder mixers

These Liag Venturi Valves are specially designed for smooth flow of powder through powder mixers. The hygienic LIAG ARC valves are the basic elements.

The inlet and outlet are positioned at an angle of 135° / 45° in a straight line to the passageway. The special construction of the Y-component combines excellent dosage control with maximum suction power. This ensures full flow without reducing the nominal diameter, which is often the case when using butterfly valves.
The LIAG Venturi Valve can replace up to two butterfly valves, improving the operational control of the system.
