The proper selection of a rotor for each unique application is directly related to the success or failure of a rotary valve, and more importantly, the entire conveying or storage system. No single rotor type can be expected to perform adequately in all applications. Variables such as product size, flowability, bulk density, chemical composition and many other aspects must be considered when selecting a rotor. Industrial Valves and Power offers a wide range of rotors to meet a myriad of conveying applications. These rotors may be fabricated from various materials including mild steel, stainless steel, and AR200/400 abrasion resistant steel. Some of the types of construction are identified below. The 8 vane rotor is our standard.

Closed End Tapered Rotor:
A closed end rotor effectively isolates the product from the end plates, providing advantages of decreased internal friction and better air lock characteristics. The tapered rotor, associated with the tapered rotary valve, offers the ability to adjust radial clearance, through linear movements of the rotor within the valve's tapered bore. This means that rotor-to-body clearance adjustments may be done while the valve is installed in the system, through one simple adjustment.

Scalloped Rotor:
Capacity reductions from 25% to 70% are possible when larger valves are specified, but a lower throughput is required.
