Regarding the market trend of pump and valve products, according to analysis, the main trends in the future are as follows:

1. With the transfer of petroleum development to inland oil fields and offshore oil fields, 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, breathing valves, flame arresters, filters, pipelines Products such as sight glasses should also change their performance and parameters according to changes in the application field of the equipment.

2. The urban construction system generally adopts a large number of low-pressure pump valves and develops toward environmental protection and energy-saving, that is, the transition from low-pressure iron gate valves used in the past to environmentally-friendly rubber plate valves, balance valves, metal seal butterfly valves, and centerline seal butterfly valves. The development of oil and gas transportation 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, 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 pumps and valves has developed from a single variety to multiple varieties and specifications. There is a growing trend that all the pump valves required for an engineering project will be provided by one pump manufacturer.
