(1) Valves for urban construction: low-pressure valves are generally used in urban construction systems, and are currently developing in the direction of environmental protection and energy saving
Environmentally friendly rubber plate valves, balance valves, midline butterfly valves, and metal-sealed butterfly valves are gradually replacing low-pressure iron gate valves. Most of the valves used in domestic urban buildings are balance valves, soft-sealed gate valves, butterfly valves, etc.
(2) Valves for urban heating: a large number of metal-sealed butterfly valves, horizontal balance valves and directly buried ball valves are required in the urban heating system. These valves solve the problem of vertical and horizontal hydraulic imbalance of the pipeline, achieve energy saving, and reduce heat generation. the goal of.
(3) Valves for city gas: City gas accounts for 22% of the entire natural gas market, and the amount of valves is large and there are many types. Mainly need ball valve, plug valve, pressure reducing valve, safety valve.
(4) Valves for long-distance pipelines: long-distance pipelines are mainly crude oil, finished products and natural pipelines. The valves that most of these pipelines require are forged steel three-piece full-bore ball valves, anti-sulfur flat gate valves, safety-run, and check valves.
(5) Valves for environmental protection: The water supply system in the domestic environmental protection system mainly needs to use the midline butterfly valve, soft-sealed gate valve, ball valve, and exhaust valve (dry to remove the air in the pipeline, and the sewage treatment system mainly needs to use the soft-sealed butterfly valve and butterfly valve.
