In urban construction, water supply, and drainage projects, low and medium-pressure valves are widely used, such as urban water pipelines mainly using large-diameter gate valves, and building construction using medium-line butterfly valves. Urban construction systems generally use low-pressure valves, environmentally friendly rubber plate valves, center line butterfly valves, metal sealed butterfly valves are gradually replacing low-pressure iron gate valves. Domestic urban construction needs valves mostly soft seal gate valves, butterfly valves, etc.
Generally speaking, butterfly valves have more advantages than gate valves in terms of construction, technical performance, and adaptability to working conditions
As the public infrastructure of the city makes clear regulations on the depth of the water supply pipeline, the height of the gate valve above DN200mm simply cannot meet the requirements, while the butterfly valve above DN600mm can meet this regulation.
When the wafer butterfly valve is connected with extra-long bolts to the valve body on the two wings of the A-B pipe it becomes a whole. The advantage of this connection is good stability, the disadvantage is that the construction operation is difficult, especially the maintenance surface of narrow lots, more difficult, while the flange butterfly valve as long as with a properly operated, stability is reliable, therefore, in the water supply pipeline network is widely used.
A butterfly valve is one of the commonly used valves in the water supply pipe. Compared with the gate valve, its advantage is more obvious, a broad range of applications and prospects.
