large height and long opening and closing time
the structure length is small
gate valves generally have two sealing surfaces, adding some difficulties to processing, grinding and maintenance
disadvantages
the overall dimensions and opening height are largethe reason is the long shutdown timeusually, the sealing surface will be welded with metal materials to increase wear resistance, such as 1cr13, stl6, stainless steel, etc
less effort when opening and closingthe space required for installation is large
during the opening and closing process, there is relative friction between the sealing surfaces, which can easily cause scratches2 cert (on request)
standards
design and manufacture conform to awwa, bs5163, din-f4,f5
dimensions conform to en1092-2,ansi b16
the shape is simple, the structure length is short, the manufacturing process is good, and the application range is wide
