The GEMÜ 660 diaphragm filling valve was successfully introduced in the beverage industry in 2007. Its main application is the aseptic filling of noncarbonated beverages such as still mineral water. Now this valve range has been extended to include the small actuator size for valves with diaphragm size 8 which enables fast and safe filling of smaller quantities. In addition to standard valve bodies, customer and machine specific special versions can be supplied. The control air connectors are positioned inline with the flow direction as standard but can also be supplied at 90° to the flow direction.
The Kv values of the small valves are between 0.5 - 2.2 m³/h, depending on the nominal size and connection. The stainless steel valve bodies are from the proven GEMÜ modular system and are therefore fully compatible with existing equipment. Connections available are butt weld spigots, clamps and threaded connections to DIN, ASME BPE, BS and JIS. The valves with EPDM and PTFE diaphragms are suitable for use up to max. 5 bar operating pressure. The required control pressure is 2 - 6 bar dependent on the design. The valves are easily cleanable and CIP/SIP capable. The maximum filling temperature for beverages is 85°C and sterilisation with steam can be carried out up to 150°C.
