Stainless Steel Wafer Butterfly Valve Type AK202 \u2014 CF8M with EPDM Seat for Industrial Piping<\/h2>\n

The stainless steel wafer butterfly valve type AK202 is a butterfly valve in CF8M (1.4408) with an EPDM seat ring. It suits industrial piping systems. Body and disc consist of CF8M (1.4408). Moreover, the shaft is AISI 420. The EPDM seat provides reliable shut-off for gases, liquids and solid-laden media.<\/p>\n

This wafer butterfly valve covers nominal sizes DN50 to DN300. It is available in pressure ratings PN10 and PN16 and mounts between PN10\/16 or ANSI Class 150 flanges. Moreover, the face-to-face length follows EN 558<\/a> Series S20. Furthermore, the mounting flange conforms to ISO 5211. As a result, it accepts lever, gearbox, pneumatic or electric actuators. The operating temperature range is \u221210 \u00b0C to +120 \u00b0C. Finally, FERGO supplies the stainless steel butterfly valve DN300 ex stock.<\/p>\n

Technical Data and Connection<\/h3>\n

The stainless steel wafer butterfly valve is available in nominal sizes DN50, DN65, DN80, DN100, DN125, DN150, DN200, DN250 and DN300. In addition, pressure ratings cover PN10 and PN16 at an operating temperature range of \u221210 \u00b0C to +120 \u00b0C. Furthermore, the wafer body mounts between mating flanges PN10, PN16 or ANSI Class 150. Moreover, the face-to-face length to EN 558 Series S20 is the standardised short length for wafer butterfly valves. In addition, the butterfly valve CF8M PN16 comes with lever, gearbox, pneumatic actuator (single-acting or double-acting) or electric actuator. Finally, optional accessories include limit switch box, solenoid valve, positioner and stem extension.<\/p>\n

Materials and Sealing<\/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 420 provides high mechanical strength. In addition, the stainless steel butterfly valve EPDM with its EPDM seat ring suits water, aqueous solutions, air and many industrial media. It is rated for temperatures from \u221210 \u00b0C to +120 \u00b0C.<\/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 wafer butterfly valve protects pipelines in chemical processing, water treatment plants, food and beverage production and other corrosive environments. In these environments, a stainless steel body is required. Moreover, the butterfly valve stainless steel CF8M handles gases, liquids and solid-laden media at temperatures from \u221210 \u00b0C to +120 \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":"
