KEY FEATURES

• Maximum number of blades in contact with body at one time without affecting throughput.
• Good throat opening at valve entry allowing high pocket filling efficiency.
• Minimum clearance at rotor tips and sides with body.
• Robust body adequately stiffened to prevent distortion.
• Heavy shaft diameters minimising deflection.
• Outboard bearings for non-contamination.
• Packing gland type seals.
• Maximising valve speed to 25 rpm -prolonging life, ensuring good throughput.
• Precision machining of components.

The prime function of a Rotary Valve is to regulate the flow of dust, powder and granular products from one chamber to another whilst maintaining a good airlock.

In the dust filtration field a good airlock is essential on cyclone and bag filter applications in order that the manufacturers quoted high dust collection efficiencies can be maintained. Airlocks are also important in the pneumatic conveying industry, where product is regulated into a pressure or vacuum conveying line while minimising air leakage.
