Universal Wafer Butterfly Valve PTFE Lined Product Information
Universal wafer butterfly valve PTFE lined is one type of wafer type butterfly valve with PTFE seat, which can match with multi-standards flanges dimensions at the same time, such as ANSI 16.1, ASME B16.5, DIN2501, BS4504, EN1092-2, JIS10K, GB 17241.6, etc. 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 can manuacture the universal wafer butterfly valve PTFE lined according to standard of API 609, MSS SP-67 with sizes of 1-1/2”~14” (DN40~350mm).
