Valves for Alumina Services

Function

VENU® valves are designed and manufactured for a wide range of slurry services, mainly for alumina refineries and other mining applications where corrosion and erosion are present.

Why VENU® Valves?

VENU® valves have been supplied to alumina refineries since 1990. The main areas of use are digestion, hydrate clarification and seed, precipitation, and calcination units.

• Changeable protective ring in the inlet area and stem protector.
• A variety of materials and coatings are available to withstand wear and tear and/or chemical corrosion of the valves.
• Thanks to our experience and flow simulation facilities, which replicate working conditions, VENU® can recommend internal coatings and designs that increase valve performance.
• The regrinding operation is included to avoid sealing problems and increase valve life.
• Different operations are adapted to the customer's plant requirements: manual, spur gear or helical gear, or actuated (electric, pneumatic or hydraulic).
• Designs for customers' special applications.
