Analysis of the five major trends in the development of the valve market

The largest users of the valve are the petrochemical industry, the power sector, the metallurgy sector, the chemical industry and the urban construction sector. The petrochemical industry mainly adopts API standard gate valves, globe valves and check valves; the power sector mainly adopts high-temperature pressure gate valves, globe valves, check valves and safety valves for power stations, and low pressure butterfly valves and gate valves for part of the water supply and drainage valves; the chemical industry mainly adopts them. Stainless steel gate valve, globe valve and check valve; metallurgical industry mainly adopts low-pressure large-diameter butterfly valve, oxygen globe valve and oxygen ball valve; urban construction department mainly adopts low-pressure valve, such as large-diameter gate valve mainly used in urban tap water pipeline; The middle line butterfly valve, metal seal butterfly valve mainly used in urban heating, etc.; oil pipeline mainly uses flat gate valve and ball valve; the pharmaceutical industry mainly uses stainless steel ball valve; the food industry mainly uses stainless steel ball valve. Due to changes in user needs, the market trend of valve products will also undergo corresponding changes. The main development trends in the future will be as follows:

1. With the shift of petroleum development to oil fields in the interior and offshore oil fields, and the development of thermal power and hydropower and nuclear power from 300,000 kilowatts or less of thermal power in the power industry, valve products should also be changed in accordance with changes in equipment applications. Performance and parameters;

2. The urban construction system generally adopts a large number of low-pressure valves, and develops to environmentally-friendly and energy-saving types, that is, the low-pressure iron gate valve used in the past has gradually turned to environmentally-friendly rubber sheet valves, balance valves, metal-sealed butterfly valves, and midline-sealed 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, steam traps must be developed and developed to subcritical and supercritical high parameters.

4. The development of the power station is going to large-scale development. Therefore, it is necessary to use large-diameter and high-pressure safety valves and pressure reducing valves, as well as fast opening and closing of valves.

5, for the needs of complete sets of 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.
