1. As oil has been developing, market trend of cast steel valve products transfer from inland oil fields into offshore oil fields. With the development of thermal power and hydropower and nuclear power from 300,000 kw to 300,000 kw in the electric power industry, valve products should be based on equipment application area to change its properties and corresponding parameters.
2. Urban construction system generally adopts a large number of low pressure valves, and is developing in the environment friendly and energy-saving direction. Namely, it transits from low pressure steel gate valve used in the past toward environmental friendly rubber plate valve, balance valve, metal sealing butterfly valve and the midline sealing butterfly valve. Oil and gas transportation engineering are developed in the direction of pipelining, thus it requires a lot of flat gate valve and ball valve.
3. The other side of the energy development is energy conservation. In terms of energy conservation, it is necessary to develop the steam hydrophobic valve, and develop toward subcritical and supercritical high parameter.
4. The construction of the power station has large-scale development trend, so it is required to use large diameter and high pressure relief valve and pressure reducing valve. At the same time, it also needs quick opening and closing valves.
5. The need of package engineering. The valve supply is developed from a single species to more varieties and specifications to meet package engineering needs. The trend of providing valves for a project by only one valve manufacturer will become bigger and bigger.
