An additional size has been added to the GEMÜ 654 valve range extending these to diaphragm size 8 (MG8) in nominal sizes DN 4 - 15. The bonnet is available with a seal adjuster but also with a stroke limiter as options. The seal adjuster in small valves in particular serves to protect the diaphragm against overcompression by the user and thus increases the service life of the diaphragm. The stroke limiter is used to manually set the required flow rate on fully opening the valve.
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. Valves with an EPDM diaphragm are suitable for use up to 10 bar and with PTFE diaphragm up to 6 bar operating pressure. The stainless steel handwheel and the bonnet are designed to be easily cleanable. The valves are CIP/SIP capable and autoclavable. With this extended size the GEMÜ 654 range is now available from DN 4 to DN 100.
