Plumbing valves mainly include radiator thermostats, gate valves, globe valves, low-pressure valves, etc. In terms of the entire valve market, valves are mainly based on the construction of engineering projects, and their largest users are urban construction departments, petrochemical industry, power department, metallurgical department, chemical industry, etc.
Of course, different industries and different departments have different valve types. For example, the power department mainly uses high-temperature pressure gate valves, check valves and safety valves for power stations, as well as low-pressure butterfly valves and gate valves for some water supply and drainage valves; the metallurgical industry mainly uses low-pressure large-diameter valves, oxygen stop valves and oxygen ball valves; The urban construction department mainly uses low-pressure valves. For example, large-diameter gate valves are mainly used for urban water pipelines, mid-line butterfly valves are mainly used for building and apartment construction, and metal sealed butterfly valves are mainly used for urban heating. Regarding the future market trends of valves, some experts have made the following analysis:
1、城建系统采用的低压阀门，应该向环保型和节能型发展，由过去使用的低压铁制闸阀逐步转向环保型的胶板阀、平衡阀、金属密封蝶阀及中线密封蝶阀过渡；
2、随着石油行业的开发向内地油田和海上油田的转移，以及电力工业由30万千瓦以下的火电向30万千瓦以上的火电及水电和核电发展，阀门产品也应依据设备应用领域变化相应改变其性能及参数；
3、电站的建设向大型化发展，所以需用大口径及高压的安全阀和减压阀，同时也需用快速启闭阀门；
4、能源发展的另一面就是节能，所以从节约能源方面看，要发展蒸汽疏水阀，并向亚临界和超临界的高参数发展；
由于阀门的用户具有相对的固定性，因此，其未来的市场走向和趋势也是随着用户行业的改革发展而变化的，也是为了更好地满足客户的需求。
