Rotary Valve Rotor Types

Rotor Type Information

First, for several of the rotor types there are two different designs offered. They are “open-end” and “closed-end” or “shrouded” rotor designs. With “open-end” design, the blades are welded directly to the rotor shaft. With “shrouded” or “closed-end” design the addition of discs are welded to the shaft and blade ends. Each design has application advantages and disadvantages.

Next, the information on the rotor types is as follows;

Type “A” Rotor

Rotary Valve RotorA 100 Rotary Valve Rotor Types

The Type “A” rotor is used for the majority of applications. It has deep pockets. Hence, it has the maximum volumetric capacity. This rotor is used for either air locking or feeder applications. Type “A” rotors have the lowest air or gas leakage and is the least expensive to build.  The Type “A” rotor is good for handling free flowing to slightly cohesive products with narrow particle sizes distribution. It’s not the best for handling any abrasive products

 

Type “AS” Rotor

Rotary Valve RotorAS 100 Rotary Valve Rotor TypesThe Type “AS” rotor has deep pockets and a closed ends. This rotor is used for either air locking or feeder applications.  It is better for handling products having a wide particle. Because of the shroud plate it is better for handling slightly abrasive products. The Type “AS” rotor is not the best for handling cohesive materials.

 

 

Type “B” Rotor

Rotary Valve RotorB 100 Rotary Valve Rotor TypesThe Type “B” rotor is designed with filled rotor pockets. This rotor is used for feeder applications where the valve flanges need to match a set size of inlet and outlet. The Type “B” rotor is good for handling free flowing to slightly cohesive products.

 

 

Type “BS” Rotor

Rotary Valve RotorBS 100 Rotary Valve Rotor TypesThe Type “BS” rotor has filled rotor pockets and closed end design. This rotor is used for feeder applications where the valve flanges need to match a set size of inlet and outlet. The Type “B” rotor is better for handling slightly cohesive products.

 

Type “C” Rotor

Rotary Valve RotorC 100 Rotary Valve Rotor TypesThe Type “C” rotor is used for metering feeding applications. It also is designed with filled rotor pockets. However, the pockets are shallower than a Type “B” rotor. This rotor is used for feeding difficult flowing cohesive products.  The shallower pockets aid in the discharge of the cohesive materials.

 

Type “CS” Rotor

This rotor is used for feeding difficult flowing cohesive and slightly abrasive products.  The shallower pockets aid in the discharge of the cohesive materials.

 

Type “D” Rotor

Rotary Valve RotorD 100 Rotary Valve Rotor TypesThe Type “D” rotor has adjustable tips. This rotor is used for either air locking or feeder applications. It can be furnished with filled pockets similar to the “B” and “C” rotor types. The tips can be adjusted to compensate for rotor tip wear. When flexible tip material is used, the type “D” rotor is the best rotors to use when handling fibrous material.

 

Type “DS” Rotor

Rotary Valve RotorBDS 100  Rotary Valve Rotor TypesThe Type “DS” rotor has adjustable tips with closed ends. This rotor is used for either air locking or feeder applications. With the end shrouds and adjustable tips, this rotor is a good choice for handling slightly abrasive products. The tips adjustment can compensate for rotor tip wear. When Urethane flexible material is used, the type “DS” rotor is the best rotor to use when handling fibrous material that is somewhat abrasive.

Type “D3” Rotor

Rotary Valve Rotor D3 100 Rotary Valve Rotor TypesThe Type “D3” rotor has adjustable tips and ends. This rotor is used for either air locking or feeder applications. The Type “D3” rotor is the best rotor to use when handling fibrous material.   The tips can be adjusted to compensate for rotor tip and end wear.
