Offset Rotary Valves
The Sunco Offset Rotary Valve is designed to handle certain types of materials that would otherwise suffer damage when handled with a typical rotary valve. Materials such as plastic pellets, nylon, polyethylene and others can break apart and the resulting “stringers” can cause a standard rotary valve to jam. This can cause material loss as well as significant downtime and increased maintenance requirements.
To address these problems, Sunco offers our Offset Rotary Valve. The unique design of the Offset Rotary Valve allows the material to be fed into the rotor during its upward cycle. In addition, a special beak above the rotor distributes the material across the entire width of the rotor. The result is a consistent feed without harm to your material or equipment.
