From the 80s onwards, the backbone enterprises in China began to introduce similar products of foreign valve design, technology and other advanced technology and processing equipment, so ourBellow Seal Valves valve manufacturing technology and product quality has been rapidly improved. Currently, the domestic production of key enterprises valve according to ISO international standards have been able to, DIN German standards, AWWA U.S. standards with international standards such as design and manufacture of various valves, some manufacturers of the products reach the international advanced level. Although the overall level of Chinese New Year valve industry have been greatly improved, but the quality is still not stable enough, such as run, run, drip, leak phenomenon occurs frequently in the domestic valve. In addition, the supporting ability of the valve compared with the developed countries there are still some gaps. Valve is a low margin product, the market is very competitive. Distribution on the valve market is mainly based on the construction of the project, the largest user of the valve is the petrochemical industry, power sector, metallurgy sector, the chemical industry and urban construction department. Main application petrochemical industry standard API gate valve, globe and check valves; power sector mainly power plants with high temperature pressure valve, globe valve, check valve and safety valve and part of a low-pressure drain valve butterfly valve, gate valve; chemical industry mainly uses stainless steel gate valve, globe valve, check valve; metallurgical industry mainly uses low-pressure large diameter butterfly valve, oxygen valve and oxygen valves; urban construction department used mainly low-pressure valves, such as urban water mainly large-diameter brake pipe valve, floor apartment building used mainly butterfly valve, the main urbanAutomatic Control Valves heating metal sealing butterfly valve; oil pipeline mainly flat gate valve and ball valve; the pharmaceutical industry mainly uses stainless steel ball valve; food industry mainly uses stainless steel ball valve and so on. Valves used in water treatment industry is large, mainly in low-pressure valve products, such as butterfly valve, gate valve, check valve. It is understood that the market has a certain amount of more than 2,000 valve companies, most located in Jiangsu and Zhejiang and the Central Plains area. Requirements of the technological content of products is relatively low, therefore, more competitive. On the one hand, China's valve products facing good opportunities for development. With the development of oil fields and offshore oil fields to the mainland the transfer, and the power industry following the 30 million kilowatts thermal power to 30 million kw of thermal power and hydropower and nuclear power development, and valves should also be based on changes in equipment, applications to change the properties of the corresponding and parameters. Urban systems generally use a large number of low-pressure valve, and to the development of environmentally friendly and energy-saving, that is, from low iron gate used in the past have gradually shifted the environment-friendly plastic sheet valve, balance valve, metal sealed butterfly valve and the transition of the center line seal . Oil and gas pipeline projects to develop in the direction, which in turn requires a lot of flat gate valve and ball valve. Energy development on the other side is energy saving, energy saving so from the side, to the development of the steam trap to the subcritical and supercritical parameters of the development of the high.

从80年代起，我国开始组织骨干企业引进国外阀门同类产品的设计、工艺等先进技术和加工设备，使我国的阀门制造技术和产品质量得到了迅速的提高。目前，国内阀门生产骨干企业已能按ISO国际标准、DIN德国标准、AWWA美国标准等国际标准设计制造各种阀门，部分厂家的产品达到了国际先进水平。虽然过年阀门行业的整体水平有了较大的提高，但质量上还不够稳定，如跑、冒、滴、漏现象在国产阀门中经常出现。另外，我国阀门的配套能力也与发达国家相比尚存在一定的旋塞阀差距。

阀门是利润率低的产品，市场竞争非常激烈。就阀门市场的分布，主要是依据工程项目的建设，阀门的最大用户是石化行业、电力部门、冶金部门、化工行业和城市建设部门。石化行业主要应用API标准的闸阀、截止阀和止回阀；电力部门主要采用电站用高温压闸阀、截止阀、止回阀和安全阀及一部分给排水阀的低压蝶阀、闸阀；化工行业主要采用不锈钢闸阀、截止阀、止回阀；冶金行业主要采用低压大口径蝶阀、氧气截止阀和氧气球阀；城市建设部门主要采用低压阀，如城市自来水管道主要采用大口径闸阀，楼寓建设主要采用中线蝶阀，城市供热主要采用金属密封蝶阀；输油管线主要采用平板闸阀和球阀；制药行业主要采用不锈钢球阀；食品行业主要采用不锈钢球阀等。阀门在水处理行业中使用量较大，主要以低压阀门产品为主，如蝶阀、闸阀、止回阀。据了解，目前市场上具有一定规模的阀门企业有2000余家，大多数分布在江浙及中原一带。由于产品鸭嘴阀技术含量要求相对较低，因此，竞争更为激烈。

一方面，我国阀门产品面临着良好的发展机遇。随着石油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。城建系统一般采用大量低压阀门，并且向环保型和节能型发展，即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。输油、输气工程向管道化方向发展，这又需要大量的平板闸阀及球阀。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。从80年代起，我国开始组织骨干企业引进国外阀门同类产品的设计、工艺等先进技术和加工设备，使我国的阀门制造技术和产品质量得到了迅速的提高。目前，国内阀门生产骨干企业已能按ISO国际标准、DIN德国标准、AWWA美国标准等国际标准设计制造各种阀门，部分厂家的产品达到了国际先进水平。虽然过年阀门行业的整体水平有了较大的提高，但质量上还不够稳定，如跑、冒、滴、漏现象在国产阀门中经常出现。另外，我国阀门的配套能力也与发达国家相比尚存在一定的差距。阀门是利润率低的产品，市场竞争非常激烈。就阀门市场的分布，主要是依据工程项目的建设，阀门的最大用户是石化行业、电力部门、冶金部门、化工行业和城市建设部门。
