Valve is the biggest user department of department of petrochemical industry, electric power, metallurgy, chemical industry and urban construction department. Due to the change of user requirements, the valve product market will also have corresponding change, for a period of time in the future the main developing trend is as follows:
1. As the oil development to the mainland oil fields and the transfer of offshore oil field, as well as the electric power industry from 300000 kw to 300000 kw thermal power under the above of the thermal power and hydropower and nuclear power development, products should be based on equipment application domain changes to change its properties and corresponding parameters;
2. Urban construction system generally USES a large number of low pressure valves, and to the development of environmental protection and energy-saving, namely by the use of low iron gate toward environmental protection rubber sheet, balance valve, the transition metal sealing butterfly valve and the midline sealing butterfly valve, oil and gas engineering to develop in the direction of pipelining, which in turn requires a lot of flat gate valve and ball valve;
3. The other side of the energy development is energy saving, so in terms of energy conservation, to develop the steam trap, and high toward the subcritical and supercritical parameter development;
4. The construction of the power station to large-scale development, so the need of large diameter and high pressure relief valve and pressure reducing valve, at the same time also need quick opening and closing valves;
5. Aiming at the need of complete sets of engineering, the valve supply by a single species to more varieties and specifications. A project required valve, provided by a valve manufacturer all trend is more and more big.
