The refurbishment valve seriously disrupts the valve market, and the user must be resistant to the valve Market.
Along with the transfer of oil development to inland oilfields and offshore oil fields, and the development of power industry from 300 thousand KW below thermal power to 300 thousand KW of thermal power and hydropower and nuclear power, we should also change its performance and parameters according to the change of equipment application. Urban construction system generally uses a large number of low pressure V ball valves, and develops towards environmental protection and energy saving. That is to say, the low-pressure iron gate valves used in the past are gradually shifting to environmental friendly rubber plate valves, balance valves, metal sealed butterfly valves and middle line sealing butterfly valves. Oil transmission and gas transmission projects develop to the direction of pipeline. In terms of energy conservation, the steam trap should be developed and developed to the high parameters of subcritical and supercritical.
The construction of the power station is developing to a large scale, so it is necessary to use the sum of large diameter and high pressure, and at the same time, it also needs to use fast opening and closing valves. The needs of a complete set of projects are developed from a single variety to many varieties and many specifications. The valve required for an engineering project is becoming more and more popular by a valve manufacturer. In general, China's price is relatively stable, although a slight rise and fall each year, but the margin is very small. Valve from the North China market, it found that many companies for profit shoddy, serious disruption of the valve market. Ask the user to resist the refurbishment valve. Many accidents come from this.
