Hardware knowledge: the future development trend of butterfly valves

According to the analysis of the market trend of valve products, the main trends in the future are as follows:

1. Market trend of cast steel valve products. With the shift of petroleum development to inland oilfields and offshore oilfields, and the development of the power industry from thermal power below 300,000 kilowatts to thermal power, hydropower and nuclear power above 300,000 kilowatts, valve products are also developing The performance and parameters of the equipment should be changed according to the changes in the application field of the equipment.

2. Urban construction systems generally use a large number of low-pressure valves, and they are developing toward environmental protection and energy-saving, that is, the low-pressure iron gate valves used in the past are gradually shifting to environmentally-friendly rubber plate valves, balance valves, metal seal butterfly valves, and centerline seal butterfly valves. transition. The development of oil and gas transportation projects towards pipelines requires a large number of flat gate valves and ball valves.

3. The other side of energy development is energy conservation, so from the perspective of energy conservation, steam traps should be developed and developed towards subcritical and supercritical high parameters.

4. The construction of power stations is developing towards large-scale development, so large-diameter and high-pressure safety valves and pressure reducing valves are required, as well as fast opening and closing valves.

5. For the needs of complete engineering, the supply of valves has developed from a single variety to multiple varieties and specifications. There is a growing trend that the valves required by an engineering project are all provided by a valve manufacturer.
