Hardware knowledge: The future development trend of butterfly valves

Valve product market trends, according to analysis, the main trends in the next period of time are as follows:

1. Market trends of cast steel valve products With the shift of petroleum development to inland oil fields and offshore oil fields, and the development of power industry from 300,000 kilowatts of thermal power to more than 300,000 kilowatts of thermal power and hydropower and nuclear power, valve products should also be based on equipment. Changes in the application area change their performance and parameters accordingly.

2. The urban construction system generally uses a large number of low-pressure valves, and develops to environment-friendly and energy-saving types, that is, the low-pressure iron gate valve used in the past has gradually shifted to environmentally-friendly rubber sheet valves, balancing valves, metal-sealed butterfly valves and midline-seal butterfly valves. The development of oil and gas transmission projects in the direction of pipelines requires a large number of flat gate valves and ball valves.

3. The other side of energy development is energy conservation. Therefore, from the perspective of energy conservation, we must develop steam traps and develop them to subcritical and supercritical high parameters.

4. The development of the power station is going to large-scale development. Therefore, large-diameter and high-pressure safety valves and pressure reducing valves are required. At the same time, valves need to be opened and closed quickly.

5. The need for complete projects, valve supply from a single species to more varieties and more specifications. The need for a valve for an engineering project is increasingly provided by a valve manufacturer.
