API 609 WAFER BUTTERFLY VALVE

API609 Wafer Butterfly Valve Product Information

API609 wafer butterfly valve is one type of ANSI standard butterfly valve, which is in need of big quantity, which is mounted between two matching flanges of the piping. According to actual piping conditions, wafer type butterfly valve can be manufactured according to different flanges standards, such as ASME B16.1, ASME B16.5. API 609 A wafer butterfly valve can be mounted on the piping end as exhaust valve. We can manufacture the API609 wafer butterfly valve with sizes of 2”~48” (DN50~1200mm)
