Rotolok Valves, Inc. Blowing Seal Valves

Blowthrough/Blowing Seals meet the specific needs of the pneumatic conveying industry, a natural extension to Rotary Airlocks; both products are used to regulate the flow of dry powder, dust or granular product, while maintaining an airlock. The blowthrough/blowing seal has distinct advantages for the specialist as it introduces high pressure conveying air through the valve body and rotor pocket ensuring – HIGH EFFICIENCY THROUGHPUT WITH LOW EFFECTIVE PRESSURE DROP. This is achieved by the fact that more blades are in contact for longer periods with the valve body resulting in less air leakage – and by blowing through the rotor each rotor pocket is efficiently emptied. The Rotolok range of seals is robustly constructed with an emphasis on close tolerances and minimal eccentricities, making the unit suitable for the majority of pneumatic conveying applications.
