Revision of our butterfly valves series AK01 & AK02

We would like to draw your attention to the revision of our butterfly valves of the AK01 & AK02 series.

The newly introduced modular principle in this series ensures numerous combination options in terms of body shape, disc material, sleeve material, nominal pressure ratings, actuating elements and approvals, thus covering a wide range of applications. 
As standard, the series is available with spigot and threaded eyes in nominal sizes DN32 to DN600 made of spheroidal cast iron with high-quality 80μm epoxy coating according to RAL 5005 and stainless steel butterfly disc. The existing standard sealing systems "EPDM DVGW drinking water", "NBR DVGW gas" and "FKM" have been extended by an EPDM seal for the high temperature range including FDA approval and are available from stock. Other sleeve materials can be offered by us on request.
