Rotary valves in solvent extractors are devices used to control the flow of materials or solvents within the system. These valves consist of a rotating mechanism that allows for precise regulation of the material’s passage through different stages of the extraction process. The rotary valve’s design typically includes a rotating blade or rotor that opens and closes ports to manage the flow effectively. This enables accurate dosing and prevents cross-contamination, contributing to the overall efficiency and reliability of the extraction operation. The durable construction of rotary valves ensures they can withstand the harsh conditions of solvent extraction, maintaining consistent performance over time.
