Universal Wafer Butterfly Valve Descriptions

Universal wafer butterfly valve is one type of wafer butterfly valve, which can meet multi-standards flanges dimensions at the same time, such as ANSI 16.1, DIN2501, BS4504, EN1092-2, JIS10K, GB 17241.6, etc at the same time. Its biggest advantage is that it can be mounted between any standard of pipe flanges freely as long as you purchase only one type of wafer butterfly valve body. So, this latest developed butterfly valve is more and more popular to our customers, because it solves the problem for our customer to change between different standards of butterfly valves. Wafer butterfly valve can be mounted on the piping end as exhaust valve. Flowspec Luokai manufacturers the universal wafer butterfly valve according to API 609 and MSS SP-67 with sizes of 1-1/2″~14″ (DN40~350mm).
