Heavy-duty Materials Offset Airlock Valve for Powder

Maximum number of blades in contact with body at one time without affecting throughput Good throat opening at valve entry allowing high pocket fillage efficiency 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 Options available for specialisationThe 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. The granule type of product, especially if it is a plastic type, polythene or nylon etc., does not shear easily and consequently, without considerable care the standard drop-through type of valve leads to valve seizure and also considerable shock loadings. To minimize these problems the Offset Rotary Valve ensures lower pocket fillage as its design means that the rotor is still being filled in the upward cycle with the pellets falling away at the shear point. Similarly, the pelican beak distributes the product across the full width of the rotor.
