The MALD and MLD medium-duty rotary valves offer exceptional value and versatility for various applications. Ideal for vacuum conveying, big bag unloading, cyclone applications, and general purposes, both rotary valves are distinguished by their simple construction and direct drive. Using the AL rotary valve body with two round flanges, the MALD rotary valve is optimal for powder handling. In contrast, the MLD rotary valve features an ML rotary valve body with larger round and square flanges, enhancing its efficiency with free-flowing products and facilitating transitions between different connections.
