Butterfly valve 
 Check Valve Model: H76H, H76Y, H76W, H76X, H76F 
 Butterfly valve for clean lines and industrial, environmental, water treatment, high-rise buildings to the drain line to prevent reverse flow of the medium used. 
 Butterfly Check Valve Features 
 1, small size, light weight, compact structure, easy maintenance 
 2, the use of dual-type valve plate, under the elastic force of the spring under their own speed closing moments 
 3, closed because of the role of speed, to prevent the media back 
 4, the length of body structure, small size, rigidity 
 5, safe and convenient, can be used for horizontal and vertical installation in both directions 
 Butterfly valve performance standards 
 1, flange size: GB/T1724.1-98 
 2, the structure length: GB/T12221-1989, ISO5752-82
