Stainless Steel Drinking Water Butterfly Valve \u2014 CF8M with EPDM Seat and DVGW Approval up to DN200<\/h2>\n

The stainless steel drinking water butterfly valve type AK210W is a butterfly valve in CF8M (1.4408) with an EPDM seat ring. This seat is approved to DVGW, ACS, WRAS, KTW and W270. Body and disc consist of CF8M. Moreover, the shaft is AISI 316. The EPDM seat is approved for drinking water service across the main European standards.<\/p>\n

The butterfly valve wafer stainless drinking water covers nominal sizes DN50 to DN200. It is available in pressure ratings PN10 and PN16 and mounts between PN6\/10\/16 or ANSI Class 150 flanges. Furthermore, the face-to-face length follows DIN EN 558-1<\/a> Series 20. The mounting flange conforms to ISO 5211. As a result, it accepts lever, gearbox, pneumatic or electric actuators. The operating temperature range is \u221220 \u00b0C to +95 \u00b0C. Finally, FERGO supplies the stainless steel butterfly valve DN200 drinking water ex stock.<\/p>\n

Technical Data and Connection<\/h3>\n

The stainless steel drinking water butterfly valve is available in nominal sizes DN50, DN65, DN80, DN100, DN125, DN150 and DN200. In addition, pressure ratings cover PN10 and PN16 at an operating temperature range of \u221220 \u00b0C to +95 \u00b0C. Furthermore, the wafer body mounts between mating flanges PN6, PN10, PN16 or ANSI Class 150. Moreover, the face-to-face length to DIN EN 558-1 Series 20 is the standardised short length for wafer butterfly valves. In addition, the butterfly valve CF8M drinking water comes with lever, gearbox, pneumatic actuator (single-acting or double-acting) or electric actuator (24 V, 230 V, 240 V AC\/DC or 400 V three-phase). Finally, optional accessories include limit switch box, solenoid valve, positioner and stem extension.<\/p>\n

Materials and Approvals<\/h3>\n

Body and disc consist of CF8M (1.4408). Moreover, this austenitic stainless steel casting offers high resistance to corrosion and aggressive media. Furthermore, the shaft in AISI 316 provides additional corrosion resistance. In addition, the EPDM seat ring is approved to DVGW for drinking water, ACS, WRAS, KTW and W270. As a result, it meets the requirements of the major European drinking water standards.<\/p>\n

Moreover, the concentric design with a centrally mounted disc ensures reliable tight shut-off. Finally, the ISO 5211 mounting flange allows direct attachment of different actuator types without adaptation.<\/p>\n

Applications and Ordering<\/h3>\n

The stainless steel drinking water butterfly valve protects pipelines in drinking water supply, water treatment plants and hygienically sensitive environments. In these environments, a stainless steel body with approved EPDM sealing is required. Moreover, the DVGW drinking water approval together with ACS, WRAS, KTW and W270 confirms suitability for drinking water pipelines across Europe. Furthermore, the butterfly valve PN16 stainless drinking water handles potable water at temperatures from \u221220 \u00b0C to +95 \u00b0C. In addition, the compact wafer design simplifies installation in existing pipelines. Finally, for custom solutions<\/a>, project quantities or technical advice, the FERGO team is available.<\/p>\n","protected":false},"excerpt":{"rendered":"
