The Niro sanitary rotary valve is the perfect design for continuous discharge of powders and granulates from a food or dairy processing application

The Niro sanitary rotary valve is the perfect design for continuous discharge of powders and granulates from a food or dairy processing application.

The Niro rotary valve consists of a tapered housing and rotor, with gear and motor drive. The tapered design enables quick and precise adjustment of the clearance between the rotor and housing. The required clearance depends upon the nature of the particulate material (e.g., powder, granules, pellets, agglomerates), operating temperatures, and pressures. There is easy cleaning accessibility and no special tools are required for maintenance.

The Niro rotary valve is applicable for the discharge of particulate material from dryers and solids handling equipment, and for coarse dosing to solid-to-solid and solid-to-liquid systems. The valve is delivered in sizes compatible with most dairy and food processing systems.

For sanitary applications, the drive of the standard design is modified so that the drive unit is separated from the product contact area. It is impossible for lubricant to contaminate the product. Oil seals can be inspected during operation, since the shaft between drive and valve housing is visible from the outside. All product contact seals can be replaced without removing the drive unit from the valve housing. Product contact surfaces are self-draining for a better CIP operation, and the finish is at least grit 150.
