The GEMÜ 567 BioStar is a stainless steel diaphragm globe control value designed for precision flow and dosing in aseptic applications, including biotechnology, food, beverage and pharmaceuticals industries.

Aseptic diaphragm valves are frequently used to control sterile applications. However, diaphragm valves soon reach their limits when a fine batch is required. Although globe valves with flow restrictors offer precise control, they are not aseptic. The GEMÜ 567 BioStar allows small volume to be regulated extremely accurately under aseptic conditions from 80 l/h to 12,500 l/h. Using innovative sealing via GEMÜ PD (Plug Diaphragm) made from an FDA-compliant PTFE diaphragm guarantees a hermetic separation of fluid from the actuator, whilst simultaneously achieving excellent valve control characteristics.

Available with manual, pneumatic and motorized actuators, the GEMÜ 567 BioStar is CIP/SIP capable and can also be integrated into GEMÜ stainless steel multi-port valve blocks.
